Solution Overview

Problem

The existing door-handle mounting structures for refrigerators are not securely fixed, leading to fluctuation and potential damage when the door is opened and closed repeatedly, affecting the operation feeling and convenience.

Innovation Solution

A mounting structure for a refrigerator door-handle that includes a handle fixture with one end inserted into the door and the other end into the door-handle, featuring a support bracket with a fixing element to maintain a robust connection, preventing detachment and damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple mounting structure is used, then the device complexity is reduced, but the connection stability between door and door-handle deteriorates

Engineering Contradiction:

Improvemounting structure complexityVSAvoidconnection stability

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

The mounting structure is divided into separate functional components: a door-handle, a handle fixture with insertion part, a support bracket, and a fixing element. This segmentation allows each component to perform its specific function while maintaining overall connection stability without excessive complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The handle fixture's insertion part is inserted into the door-handle, and the support bracket is inserted into the door. The fixing element then secures the nested structure by fixing the insertion part to the support bracket, creating a stable nested connection that prevents fluctuation.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of manufacture

If a simple mounting structure is used, then the ease of manufacture is improved, but the reliability of the door-handle connection deteriorates

Engineering Contradiction:

Improvemounting structure manufacturabilityVSAvoidconnection reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

Dividing the mounting structure into separate manufacturable components (door-handle, handle fixture, support bracket, fixing element) allows each part to be manufactured independently using standard processes, then assembled to create a reliable connection system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The handle fixture and support bracket act as intermediary components between the door and door-handle, providing a reliable connection mechanism that prevents direct stress concentration and detachment while maintaining ease of assembly.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the connection between door and door-handle is not solid, then the ease of operation is improved, but the door-handle fluctuation and potential damage increase

Engineering Contradiction:

Improvedoor operation easeVSAvoiddoor-handle fluctuation and damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of making the door-handle itself flexible or movable to ease operation, the invention uses a solid fixed connection structure with the fixing element that prevents fluctuation, allowing smooth operation without compromising connection stability.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The support bracket and fixing element are designed beforehand to prevent fluctuation and damage before they occur, creating a robust connection that withstands repeated opening and closing operations without deterioration.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
