This document discusses applying value engineering techniques to enhance the value of a slit housing component used in microscopes. The current slit housing design and manufacturing process were analyzed. Alternative designs and materials were brainstormed, and options were evaluated based on criteria like ease of use, durability, and cost. Implementing the proposed design changes resulted in a 36.79% reduction in per unit cost, translating to annual savings of over Rs. 573,200 for an annual demand of 10,000 units. The value engineering goals of identifying unnecessary functions, adding desirable functions, and reducing costs through eliminating redundancies were achieved.

1. Enhancing Value of Slit Housing

2. Introduce the product
 In this presentation we have discussed a part of the company Labotron India
Pvt. Ltd. located in Ambala which produces medical instruments.
 The part considered is Slit Housing on which the value engineering job plan is
applied.
 Product selected is Slit Housing which is used as a component in assembly of
microscope in the field of eye inspection at moisture free environment.

3. The steps used for this purpose are as follows:
 Product selection plan
 Gather information of product
 Functional analysis
 Creativity worksheet
 Evaluation sheet
 Cost analysis
 Result

4. Product information

5. Functional analysis of present function

6. Develop alternative Design or Methods
During brainstorming these ideas were listed:-
i. Change material
ii. Change design
iii. Use ASB plastics
iv. Change the process
v. Make product through casting

7. Evaluation phase
For judging the ideas, the following designs were considered:
A: Ease of operation
B: Durability
C: Maintainability
D: Safety
E: Reliability

8. Comparing this criteria according to relative importance :

10. Cost analysis

11. Result
The total savings after the implementation of value engineering are given below:-
 Total Existing Cost – Rs 155.8/-
 Total Proposed Cost –Rs 98.48/-
 Saving per product – Rs 57.32/-
 Percentage saving per product –36.79%
 Annual Demand of the product – 10,000
 Total Annual Saving – Rs 5,73,200/-
 Value Improvement - 58.20%

12. Three goals that we’re looking at value engineering:
1. Identify additional functions that aren’t attractive to customers.
2. Add attractive functions for customers.
3. Saving because of the elimination of redundant functions.
