Vehicle Fuse Box Protection With Pre-Holding for Frontal Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle fuse boxes are vulnerable to damage during collisions, particularly frontal impacts, which can disrupt the electrical supply to safety devices, rendering them inoperative.
Innovation Solution
A protective device comprising a fuse box arrangement with a pre-holding mechanism, such as a notch, and a protective cover made of sheet metal, which holds the fuse box in a mounting position to facilitate assembly and protects it during impacts by allowing lateral movement and pivoting, ensuring the fuse box remains undamaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fuse box is mounted close to the battery in the front compartment, then the electrical supply to safety devices is ensured, but the fuse box becomes vulnerable to damage during frontal collisions
Solution Approach 1:
The fuse box is pre-positioned in a mounting position above the battery using a pre-holding mechanism (notch) before collision occurs. This preliminary positioning allows the fuse box to be close to the battery for reliable electrical supply while being held in a protected location that prevents direct impact damage during frontal collisions
Solution Approach 2:
The protective device acts as an intermediary between the fuse box and the battery, allowing the fuse box to be mounted close to the battery while preventing direct contact and potential damage. The protective device mediates the spatial relationship, enabling both proximity for electrical reliability and separation for collision protection
2Ease of manufacture
If the fuse box is held in a fixed mounting position, then assembly is facilitated, but the fuse box cannot move laterally to avoid impact during collision
Solution Approach 1:
The pre-holding mechanism provides a dynamic solution where the fuse box is constrained in a specific mounting position during normal operation and assembly, but can move laterally when needed during collision. The notch provides initial positioning for ease of assembly, while the protective device allows controlled movement to avoid impact, transitioning from static positioning to dynamic adaptability
Solution Approach 2:
The system changes the positional parameters of the fuse box based on conditions. During assembly and normal operation, the fuse box is held in a fixed position (defined by the notch) for ease of manufacture. During collision, the protective device allows lateral movement, changing the position parameters to avoid impact while maintaining electrical connection
