Solution Overview

Problem

Conventional refrigeration devices require costly and complex disassembly to access the electronic module for repairs or testing, compromising production safety and reliability due to the module being covered by the front panel during assembly.

Innovation Solution

A refrigeration device design featuring a receiving shaft extending from the outer edge of the housing part, allowing the electronic module to remain freely accessible without removing the front panel, with extraction means and a transparent viewing window for external operation and inspection, enabling final assembly and functional testing post-manufacture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the electronic module is pre-assembled inside the housing part before attaching the front panel, then the assembly sequence is simplified during manufacturing, but the electronic module becomes inaccessible for testing, repair, or replacement without dismantling the front panel

Engineering Contradiction:
Improveassembly sequenceVSAvoidaccessibility of electronic module
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The housing part is segmented into the front panel and the main body with a receiving shaft. The electronic module is mounted in the receiving shaft that extends through the front panel, allowing the module to be accessed by removing only the front panel rather than disassembling the entire housing. This segmentation enables independent access to the electronic module while maintaining a simplified assembly process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The receiving shaft acts as an intermediary structure that extends from the front panel into the housing part. This intermediary element allows the electronic module to be mounted in a position that is both accessible from the front panel side and integrated into the housing structure, enabling testing and repair without complete disassembly while maintaining assembly simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Shape

If the electronic module is covered by the front panel during assembly, then the appearance is clean and integrated, but production safety is compromised as functional testing cannot be performed on the fully assembled device

Engineering Contradiction:
Improveintegrated appearanceVSAvoidproduction safety
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The receiving shaft is pre-integrated into the housing part structure before final assembly. This allows the electronic module to be mounted in advance in a position that enables functional testing while maintaining the integrated appearance when the front panel is attached. The preliminary preparation of the receiving shaft ensures that testing can be performed before the front panel is permanently fixed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The receiving shaft extends in a dimension perpendicular to the front panel surface, allowing the electronic module to be positioned such that it can be accessed and tested from the front while maintaining a clean integrated appearance when viewed from the exterior. This dimensional arrangement enables both aesthetic integration and functional accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of repair

If the front panel is removed to access the electronic module, then the module becomes freely accessible for testing and repair, but the process becomes costly and complicated

Engineering Contradiction:
Improveaccessibility of electronic moduleVSAvoiddisassembly process
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The housing is segmented such that the front panel can be independently removed to access the electronic module mounted in the receiving shaft. This segmentation allows access to the electronic module by removing only the front panel rather than disassembling the entire device, significantly reducing the complexity and cost of repair and testing operations.

Inventive Principle:
Principle #1Segmentation
