Understanding User Needs and Satisfying ThemAggregage
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs

Satronix Energy saver is a field - proven thyristorised micro controller based unit. Energy saver is able to instantly detect by
microprocessor control any change in load variation & automatically adjust the output voltage by matching output to load. The
losses (iron/magnetizing & copper loss) inherent in all AC induction motors are thereby considerably reduced dramatically.
Thus improving the motor efficiency and reducing electricity bills. The soft start facility is incorporated in all 3 Phases of the
Energy saver. It provides a gradual and controlled increase (soft start)/ (decrease in case of soft stop) in the voltage applied to
the motor terminals, thus eliminating the high peak current created during the starting cycle of induction Motors.

Savings upto
By giving you control over your energy consumption, Energy Saver will save between 15% to 40% of your
electricity costs without any loss of power and without being detrimental to your motor. Instead it will
decrease motor wear and tear. Saving costs both ways: Electricity and Life of the motor
The Problem
Much of industry is driven by AC induction motors, which are the world's most common form of
electromechanical engineering, consuming typically 70% of all electricity generated. This high energy
consumption has a high financial cost to you and a high cost to the planet in terms of depleted resources
and global warming.
Induction motors have distinct inefficiences in that they cannot effectively adjust the amount of electricity
they consume for the work they do. When they operate under less than full load, substantial power is
wasted.
The Solution
Energy Saver corrects this inefficiency. The units, designed to be simply fitted to single or three phase
motors, will give soft start, energy control, soft stop, improved reliability and increased productivity.
Motors can consume electricity at more than ten times their capital cost each year. By controlling your
efficiently, Energy Saver can save between 15% and 40% of your electricity costs; without reducing
speed, without any loss of power and without being detriment to your motor or load.
Note: The Energy Saver is not required for applications where the motor runs at full load conditions at all
given times.
4. In all applications ENERGY SAVER accommodates and manages the
high starting torque demands of certain systems ensuring reliable Applications
starting and control of power at all times.
Heat in the motor is also reduced by use of ENERGY SAVER thereby
diminishing waste and improving pull-down times in all applications.
Injection Moulding
On injection moulding systems Energy Saver controls the start and
power management of the primary hydraulic pump or pumps. It
readily accomodates the very rapid load transitions typical of
Injection Moulding and smoothes peak current excursions to reduce
potential kVA impact on supplies.
Typical system savings on the majority of installations are between 12
and 20% providing paybacks of between 12 and 15 months.
Air Compressors
Air compressors typically spend over 40% of their operating life with
the drive motor off-load. In these periods ENERGY SAVER provides
dramatic savings reducing overall consumption by up to 25%
providing paybacks in certain cases of less than 12 months.
In screw compressors ENERGY SAVER additionally manages
the rapid load transition and reduces the impact on seals, reducing
wear and increasing life between service providing additional cost
savings to the User.
Escalators
Escalator drive motors provide a distinct opportunity for ENERGY
SAVER where they have proven themselves to provide effective
management over prolonged periods of time with savings of
typically 17 – 20% and payback periods of less than 15 months
even when operating for only 14 hours a day.
ENERGY SAVER can also be effectively integrated into moving
walkways and baggage conveyor systems with equally good
savings.
Fluid Pumps
Industrial applications are wide and varied, incorporating many, if not all of the other applications. High
pressure, high volume water pumps such as those shown are suitable applications for ENERGY
SAVER, additionally providing soft-stop control to overcome water-hammer whilst also providing
savings. Savings greater than 14% can be achieved, giving a payback of less than 18 months.
5. Refrigeration
Refrigeration Compressors are commonly used for AC induction motors. The Energy Saver provides energy
management solutions from commercial kitchen fridges & freezers up to industrial refrigeration systems.
Savings range from typically 12 – 20% for the three phase systems giving pay back periods of 12 – 18
months. Savings of up to 45% on single phase systems, such as Bottle Coolers, have been achieved giving
paybacks of less than 20 months.
Air Conditioning
Air conditioning systems are in effect refrigeration systems with air movement. Single-phase units
predominate, ENERGY SAVER can provide significant savings of up to 30% on the main compressor
motors giving pay back periods of typically less than 24 months.
Three phase systems can be found in many "central air conditioned" environments such as office blocks,
restuarants and hotels. These units can be of significant size, (many up to 500kW). Savings are excellent
in these areas yielding 12 - 17% with paybacks in many cases less than twelve months.
Air Handling
Air handling systems vary considerably, single phase or three phase, ENERGY SAVER provides
controlled start and energy management where required. Though constant load, savings of 12 – 15% can
be achieved and paybacks of less than 24 months are typical. Many air handling systems use high slip
motors where DVR's can be used to provide cost effective speed control without the complications or cost
penalty typical with variable speed drives.
Grinders, Crushers and Mills
Grinders and crushers are many and varied with applications from quarries and mining through flour mills
and cereal manufacturers to animal feed producers.ENERGY SAVER has been used to effectively control
the start and stop of abattoir bone grinders, reducing loading and damage to the drive train as well as
giving savings of 15% and a pay back of less than 18 months.
6. Soft Starter
The Problem During start-up, all AC induction motors develop
substantially more torque than they require. Up to ten times full
motor load current is drawn during uncontrolled rapid motor
acceleration. At this time voltage dips, brownouts,
overheating, contactor wear and system failure can result.
Due to which there is excessive wear creating failure of the
related equipment which can result in production losses and
tons of grief over maintenance to put it right.Many sites use
Star-Delta starters but this only provides a partial solution to
the problem as high peak currents are still experienced during
the transition period when the motor briefly slows down when
switching from Star to Delta.
The Solution :By providing a controlled release of power, (torque), to the motor during start up, Soft
Starter provides smooth, stepless acceleration and, (if required), deceleration, (soft stop). It delivers an
economical and extremely reliable solution to all starting problems and is fully configurable for all
applications. Increasing life of motors and peripherals and reduces high-shock load, backlash, Vee-belt
stress, noise and vibration; thereby reducing damage to motor and load bearings and motor windings.
