Solution Overview
Problem
The challenge is to mount rigid high-voltage power lines in a vehicle in a simple and reliable way while preventing overheating and ensuring anti-shift protection.
Innovation Solution
A holding device with a fixing unit and a holding unit, featuring an inner-rib structure with bar and holding elements, is used to securely hold and space apart rigid power lines, preventing slippage and allowing for effective cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If rigid power lines are mounted closely together to save space, then the device complexity is reduced, but local overheating occurs due to insufficient cooling
Solution Approach 1:
The holding device introduces a spatial dimension by using a U-shaped profile with an inner rib that extends into the space between the power lines. This rib creates a predetermined minimum distance between adjacent power lines, enabling cooling channels to be routed through the holding device structure itself. By transforming the mounting approach from a simple clamping mechanism to a three-dimensional structured holder, the patent resolves the contradiction between compact mounting and adequate cooling spacing.
2Reliability
If rigid power lines are held firmly to prevent shifting, then reliability is improved, but the structure becomes more complex requiring additional anti-shift mechanisms
Solution Approach 1:
The patent combines multiple functions into a single integrated holding device structure. The U-shaped profile simultaneously provides mechanical support, positioning, anti-shift protection through the inner rib, and cooling channel integration. The holding elements and positioning features are merged into the monolithic U-shaped structure rather than being separate components, thereby achieving reliable anti-shift protection without proportionally increasing device complexity.
Solution Approach 2:
The inner rib acts as an intermediary element that extends into the space between power lines to maintain predetermined minimum distances. This rib structure mediates between the need for firm holding and the requirement for cooling spacing, providing both mechanical support and thermal management functionality through a single structural feature.
3Temperature
If cooling channels are integrated into the holding device, then overheating is prevented, but manufacturing complexity increases
Solution Approach 1:
The cooling channels are pre-integrated into the holding device structure during manufacturing, rather than being added as separate components afterward. The U-shaped profile is designed with internal cavities that form the cooling channels, allowing coolant to be routed through the holding device itself before the power lines are even installed. This preliminary integration of cooling functionality simplifies the overall system assembly and installation process.
