Refrigeration unit having receiving slot for an electronic module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigeration devices require dismantling of the front panel to access and test the electronic module, which is costly, complicated, and compromises production safety due to the assembly sequence where the module is pre-assembled and covered, making post-assembly testing or repairs difficult.
Innovation Solution
A refrigeration device design featuring a receiving shaft extending from the outer edge of the housing part into its interior, allowing the electronic module to remain freely accessible without removing the outer wall, enabling insertion and testing after assembly, with a transparent viewing window for operation and inspection, and a heat-insulating layer for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electronic module is pre-assembled and covered by the front panel before final assembly, then the assembly sequence is mandatory and the front panel structure is simple, but the electronic module becomes inaccessible for testing and repair without dismantling the front panel
Solution Approach 1:
The patent divides the front panel assembly into separate functional components: a removable cover element that can be detached from the housing part, allowing access to the electronic module while maintaining the aesthetic appearance of a solid front panel when assembled. This segmentation enables independent access to the electronic module without compromising the overall front panel structure.
Solution Approach 2:
The patent extracts the electronic module from the traditional enclosed position behind the front panel and relocates it to a receiving shaft that is accessible from the outer edge of the housing part. This extraction allows the electronic module to be inserted, removed, and tested independently while the front panel remains intact and aesthetically pleasing.
2Device complexity
If the electronic module is pre-assembled and covered by the front panel, then the front panel structure is simplified, but production safety is compromised as final functional testing cannot be performed on the fully assembled device
Solution Approach 1:
The patent enables preliminary functional testing of the electronic module at multiple stages: first as a standalone component before insertion into the receiving shaft, and again after insertion but before final assembly with the front panel. This preliminary action ensures that any defects are detected early in the production process, improving production safety without complicating the front panel structure.
Solution Approach 2:
The patent introduces dynamic accessibility to the electronic module through a removable cover element and a receiving shaft design that allows the module to be inserted and removed. This dynamic structure enables flexible testing and quality control procedures at different production stages while maintaining a simple, static appearance when the device is fully assembled.
3Ease of repair
If the front panel is removed to access the electronic module for repair or replacement, then the electronic module is freely accessible, but the process becomes costly and complicated
Solution Approach 1:
The patent extracts the electronic module from the traditional enclosed position and places it in a receiving shaft that is accessible from the outer edge of the housing part. This extraction allows the electronic module to be removed and replaced by simply detaching the cover element, eliminating the need to dismantle the entire front panel assembly and significantly simplifying the repair process.
Solution Approach 2:
The patent changes the access dimension for the electronic module from a front-facing approach (requiring front panel removal) to a lateral approach through the outer edge of the housing part. This dimensional change allows access to the electronic module through the receiving shaft without interfering with the front panel structure, making repairs simple and cost-effective.
