Electronic Box Mounting Assembly with Integrated Cable Trough
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for attaching and protecting electronic boxes in diesel vehicles under the body, such as those used for exhaust gas pollution control, face issues with damage from external elements like gravel, water, and shocks, and add weight and complexity with the use of heat shields and multiple assembly parts.
Innovation Solution
A fixing assembly for electronic boxes that includes a support with a shell and snap-in tabs, a cable path with inclined portions, and hooks for cable retention, which integrates with the vehicle's body to protect the box from external elements without the need for a heat shield, using lightweight and corrosion-resistant materials like aluminum or composites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a heat shield is used to protect the electronic box from external elements, then protection against damage is improved, but vehicle weight increases
Solution Approach 1:
The support structure is merged with the heat shield into a single integrated component. The support includes a shell forming a reserve for the electronic box and integrates cable trays and fixing means, eliminating the need for separate heat shield and support parts while maintaining protection functionality.
Solution Approach 2:
The support structure serves multiple functions simultaneously: it provides mechanical support for the electronic box, acts as a heat shield, protects against external elements, and integrates cable management. This multi-functionality reduces the number of separate components needed.
2Object-affected harmful factors
If a heat shield and separate support structure are used, then protection is improved, but assembly time increases
Solution Approach 1:
The support structure is merged with the heat shield into a single integrated component. The support includes a shell forming a reserve for the electronic box and integrates cable trays and fixing means, eliminating the need for separate heat shield and support parts while maintaining protection functionality.
3Object-affected harmful factors
If multiple separate parts are used for support and heat shield, then protection is improved, but device complexity increases
