Electric Control Box Water-Guiding Structure to Eliminate Seal Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric control boxes for air conditioners face issues with water infiltration due to the use of rubber seal rings and sealants, which complicates production and reduces efficiency.
Innovation Solution
The design incorporates an inner and outer water-guiding part to create a water guide passage that directs water outside the housing, eliminating the need for seal rings and sealants, and featuring a water shield and arc plate configuration to enhance waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rubber seal rings and sealants are used to seal the cooling fins, then the waterproof effect is improved, but the production process becomes more complex and production efficiency decreases
Solution Approach 1:
The patent extracts and eliminates the seal ring and sealant from the waterproofing system, replacing them with a water guide passage structure that inherently directs water away from the electric control box without requiring additional sealing components
Solution Approach 2:
The water guide passage structure performs the waterproofing function through its own geometric design, where the inner and outer water-guiding parts create a channel that passively guides water away, making the system self-sufficient without external sealing materials
2Reliability
If rubber seal rings and sealants are used to seal the cooling fins, then the waterproof effect is improved, but the production efficiency decreases
Solution Approach 1:
The patent removes the time-consuming sealing processes involving seal ring installation and sealant application, replacing them with a streamlined water guide passage structure that can be integrated into the housing in fewer steps
Solution Approach 2:
The water guide passage structure combines the housing structure with the waterproofing function into a single integrated component, eliminating the need for separate sealing materials and simplifying the assembly process
3Reliability
If rubber seal rings and sealants are used to seal the cooling fins, then the waterproof effect is improved, but the structure becomes more complex
Solution Approach 1:
The patent extracts the sealing function from the traditional seal ring and sealant combination and reimagines it as an integrated water guide passage structure that is part of the housing itself, reducing the total number of components
Solution Approach 2:
The water guide passage structure serves multiple functions: it provides structural support for the cooling fins, directs water away from the electric control box, and creates the waterproof barrier, replacing what previously required multiple separate components
