Refrigerator Electronics Mounting Shaft for Front-Panel-Free Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigeration devices require dismantling of the front panel to access the electronics module for testing or repairs, which is costly and complicated, and prevents pre-assembly electrical function testing, compromising production safety.
Innovation Solution
A refrigeration device design featuring a receiving shaft extending from the outer edge of the housing part into its interior, allowing the electronics module to remain freely accessible without removing the outer wall, enabling insertion and testing post-manufacture, with a glass panel forming the outer wall and a transparent viewing window for external operation of controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronics module is pre-assembled inside the housing part before attaching the outer wall, then the assembly sequence is mandatory and the outer wall provides protection, but the electronics module becomes inaccessible for testing and repairs without dismantling the outer wall
Solution Approach 1:
The patent divides the housing part into separate components: the outer wall (front panel) and the receiving shaft embedded in the housing body. The electronics module is mounted in the receiving shaft, which remains accessible from the outer edge of the housing part even when the outer wall is attached. This segmentation allows the outer wall to provide protection while the receiving shaft maintains accessibility for testing and repairs.
2Ease of repair
If the front panel is removed to access the electronics module, then repairs and replacements become possible, but the process becomes costly and complicated
Solution Approach 1:
The patent extracts the electronics module mounting function from the traditional enclosed assembly and places it in a dedicated receiving shaft that extends to the outer edge of the housing part. This allows the electronics module to be accessed, removed, or replaced by simply reaching into the receiving shaft from the outer edge, without needing to remove the outer wall or perform complex disassembly operations.
3Manufacturing precision
If the electronics module is tested only before attaching the front panel, then electrical function testing is possible, but production safety is compromised because faults detected after assembly require complete dismantling
Solution Approach 1:
The patent enables preliminary electrical function testing of the electronics module by providing access to the module through the receiving shaft at the outer edge of the housing part. This allows testing to be performed at any stage of assembly or even after final assembly, eliminating the need to dismantle the front panel for testing and thereby improving production safety.
