Solution Overview
Problem
Existing electronic units in vehicles face challenges in securing mechanical hold, improving electromagnetic compatibility (EMC), and enhancing thermal contact, which are essential for efficient operation and protection from environmental factors.
Innovation Solution
The use of clips attached to the housing of electronics units, which provide a mechanical hold by attaching to the vehicle panel, facilitate thermal energy transmission, and mitigate electromagnetic interference (EMI) by ensuring robust EMC and thermal contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If electronic units are mounted in vehicles, then electronic capabilities increase, but thermal energy management and EMI protection become problematic
Solution Approach 1:
The patent introduces clips as intermediary components between the electronic unit housing and the vehicle panel. These clips serve as thermal pathways that conduct heat away from the electronics, and as EMI barriers that block electromagnetic interference. The clips mediate the thermal and electromagnetic interactions without requiring direct contact between the housing and panel.
Solution Approach 2:
The mounting system is segmented into separate functional components: the housing, the clips, and the vehicle panel. The clips are detachably attached to the housing and can be independently optimized for thermal conduction and EMI shielding functions, allowing the electronic unit to be mounted without compromising thermal management or EMI protection.
2Extent of automation
If electronic units are mounted in vehicles, then electronic capabilities increase, but mechanical securing becomes challenging
Solution Approach 1:
The clips incorporate resilient portions that can elastically deform during installation and operation. This dynamic property allows the clips to flex into position, secure firmly to the panel, and accommodate thermal expansion or vibration without failing the mechanical connection. The resilient nature provides continuous contact force to maintain mechanical hold.
3Temperature
If clips are added to provide thermal and EMI management, then thermal conduction and EMI shielding improve, but device complexity increases
Solution Approach 1:
The clips are designed as multi-functional components that simultaneously provide mechanical attachment, thermal conduction, and EMI shielding. By combining these functions into a single component rather than using separate elements, the patent reduces overall system complexity while achieving all required performance goals.
Solution Approach 2:
The clips are made from electrically conductive material that also具有良好的 thermal conduction properties and mechanical strength. This composite material approach allows a single material to satisfy multiple requirements (structural, thermal, and electromagnetic) rather than requiring layered or assembled structures.
