Wire Protector Structure for Crash-Load Stud Bolt Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protectors for vehicle wires fail to provide adequate protection against impact loads during crash tests, leading to potential interference between wires and peripheral components.
Innovation Solution
A protector with a protrusion housing body that houses protrusions from peripheral components, such as stud bolts, to prevent interference with external wires during normal travel and absorbs impact loads, maintaining the protection function even under crash conditions.

Engineering Contradiction Analysis
1Reliability
If the protector structure is enhanced to protect against impact loads, then wire protection function is improved, but device complexity increases
Solution Approach 1:
The main body and protrusion housing body are merged into a single integrated protector assembly. This combining approach provides comprehensive protection against both normal traveling external inputs and crash test impact loads without requiring separate protective devices, thereby enhancing protection while controlling structural complexity.
Solution Approach 2:
The protector is designed with multi-functionality: the main body protects during normal traveling, while the protrusion housing body provides additional crash protection. This universal design allows a single device to handle multiple protection scenarios, improving reliability without proportionally increasing complexity.

AI summary
A protector (1) includes: a protector main body (10) that houses a protection target part (We1); and a protrusion housing body (20) that is connected to the protector main body (10) and houses a protrusion (Pr) from a wall face (Bd1). The protrusion housing body (20) includes: a first wall body (21) that surrounds the protrusion (Pr) inserted from a first opening (21a); and a second wall body (22) that closes a second opening at another end of the first wall body (21). In order to prevent the protrusion (Pr) from contacting the second wall body (22), the first wall body (21) is formed in a cylindrical body that is longer in a cylinder axis direction than a maximum protrusion amount of the protrusion (Pr) from the wall face (Bd1), and the second wall body (22) is interposed between an external wire (Weh) and a tip of the protrusion (Pr).
