Engine Housing Cable Fixing Flange for Low-Profile HV Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable attachment methods for high-voltage bundles in vehicle engines result in a significant vertical footprint and are cumbersome, complicating the assembly process.
Innovation Solution
A cable fixing arrangement comprising a base and a removable fixing flange made of metallic materials, optionally with an intermediate plastic shell, which allows for a more compact and efficient cable securing by minimizing vertical space and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a removable metal bracket with flange is used to attach high-voltage cable bundles to the housing, then the cables are securely held, but the vertical footprint becomes significant
Solution Approach 1:
The patent merges the base and housing into a single integrated component made of one material, eliminating the need for separate mounting brackets and flanges. This integration reduces the vertical footprint while maintaining secure cable attachment through the unified structure's inherent geometry and attachment features.
Solution Approach 2:
The fixing device is segmented into a base integrated with the housing and a separate removable flange assembly. This segmentation allows the flange to be detached for cable installation while the base remains permanently integrated with the housing, reducing overall vertical space requirements compared to traditional full-bracket designs.
2Reliability
If a traditional removable bracket system is used for cable attachment, then cables can be secured, but the assembly process becomes cumbersome and complex
Solution Approach 1:
By merging the base with the housing structure and using a unified material construction, the patent eliminates multiple separate components that would require complex assembly. The integrated design with built-in attachment features simplifies the assembly process while maintaining reliable cable retention through the unified structural design.
3Adaptability or versatility
If multiple separate components are used for cable fixation, then adaptability is improved, but the number of parts and assembly steps increases
Solution Approach 1:
The base integrated with the housing serves multiple functions: structural support, cable routing guidance, and attachment mechanism. The removable flange provides both retention and access functions. This multi-functionality reduces the number of separate parts needed while maintaining the adaptability to secure cables effectively.
