Solution Overview

Problem

Current support assemblies for motocondensing units in refrigerators require oversized vacuum chambers for helium leak testing due to the inclusion of both mechanical and electronic units, leading to increased costs and potential contamination of test results.

Innovation Solution

A modular support assembly with separate bases for the mechanical and electronic units, allowing individual testing of the mechanical unit and enabling the use of smaller vacuum chambers, along with a partition wall to segregate compartments and a cover casing for protection and insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a single base support assembly is used to hold both mechanical and electronic units, then the relative position between components is stable and they can be handled as a single body, but the entire support assembly must be introduced into the vacuum chamber for testing, requiring oversized vacuum chambers and increasing costs

Engineering Contradiction:
Improverelative position stabilityVSAvoidvacuum chamber size
Core Design Contradiction:
Stability of the object's compositionVSVolume of stationary object

Solution Approach 1:

The support assembly is divided into a first base for the mechanical unit and a second base for the electronic unit, which can be separately tested. This segmentation allows the mechanical unit to be tested alone in a smaller vacuum chamber, eliminating the need to include the electronic unit in the testing process.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a single base support assembly is used, then components can be handled as a single body, but testing equipment costs increase due to oversized vacuum chambers

Engineering Contradiction:
Improvehandling as single bodyVSAvoidtesting equipment cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The support assembly is segmented into separate bases that can be coupled together. This allows the mechanical unit to be tested independently on a smaller, more cost-effective vacuum chamber, while the electronic unit remains separate and does not contribute to testing costs.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the entire support assembly is introduced into the vacuum chamber for testing, then complete system testing is possible, but the presence of the electronic unit causes contamination of test results and requires oversized chambers

Engineering Contradiction:
Improvetesting completenessVSAvoidtest result contamination
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The electronic unit is extracted from the testing process entirely. The mechanical unit is tested independently on the first base, eliminating sources of contamination from the electronic unit while maintaining sufficient testing reliability for the mechanical components.

Inventive Principle:
Principle #2Taking out (Extraction)
