This document describes a redesign project for a juice ladle used at IIITDM. It outlines issues with the existing ladle like heavy spilling and inability to reach juice at the bottom of containers. Two redesigned concepts - the "High Heeler" and "Pringle" ladles - aim to address these by having more intuitive shapes. The existing ladle is reverse engineered and analyzed. User research feedback and market studies informed the redesign process. Load tests and other analyses were conducted on the concepts. The document concludes by noting the redesigns improve the use case and outlines future work like analyzing manufacturing costs.

4. The Soup ladle
A ladle (dipper) is a type of spoon used for soup, stew, or other foods. Although
designs vary, a typical ladle has a long handle terminating in a deep bowl, frequently
with the bowl oriented at an angle to the handle to facilitate lifting liquid out of a pot
or other vessel and conveying it to a bowl.

5. Why a “Juice” Ladle?
A Ladle is generally used to serve thick stew/soup. In IIITDM they employ a ladle to serve Juice
, hence the title of the study is coined as “Juice Ladle Design”.
The above mentioned implement belongs to the portfolio of cutlery designed for the
commercial kitchen.
The Juice Ladle possesses two key functional elements:
The Ladle head
The Stalk/ handle
The Ladle head is secured to the handle through a rivet.

7. Rationale for Product Choice
User Research

8. Learningsfrom
User Research
(1/4)
Heavy Spill during use.
No fill, only Spill!

9. Learningsfrom
User Research
(2/4)
Needs multiple passes to
fill a 300ml glass’s worth
of juice from the
container
Can’t get more
than a shot’s
worth of juice in
one go

10. Learningsfrom
User Research
(3/4)
Ladle ineffective for
drawing juice from the
bottom of the container
Geez, I cant get some
juice…
I get what you feel
bro…

11. Learningfrom

(4/4)
The use case is un-intuitive

12. Summary : Issues -> Design Changes
Issues Design Directions
• Heavy Spill during use.
• Needs multiple passes to fill a 300ml glass’s worth of
juice from the container
• Understand the use case.
• Identify factors responsible for spill.
• Identify number of passes required.
Ladle ineffective for drawing juice from the bottom of the
container
• Geometry of ladle head?
• Length of Stalk a constraint ?
The use case is un-intuitive • Rethink form?
• Alternate ways to approach problem ?
• Morphology?

13. Market Research
Suppliers (large Scale) Consumer Market

14. Suppliers
• Available 180 Rs onwards.
• National and International Suppliers
• Use Stainless Steels

15. Consumer Market
• Available standalone or as a
part of a cutlery set
• Prices are variant, depending
on whether local or imported.
Also dependent on whether
sold in loose or in a set.

20. Draft (failed)
Why did it fail?
It failed due to the free form
modelling I used to design a
major part of the stalk.I chose
a wrong paradigm to design
the stalk of the ladle and was
unable to correct it later.
Remodeling the ladle would
solve the problem.

36. Conclusions
The report aims at solving the issues faced by the IIITDM cohort while helping
themselves to a cup of juice using a commercial juice ladle . A sample user study was
conducted and user feedback was collected. The existing juice ladle was reverse
engineered and modelled using FUSION 360 and a cost analysis was performed. The
user feedback drove the redesign process and two products the “High heeler” and
“Pringle” were conceptualised. The design direction was influenced by the need for
an intuitive use case.

37. Future Directions
Manufacturing Process chain for new design
Identify cost of new design(s)
Morphology for identifying alternative solutions
