Solution Overview
Problem
Conventional wire harness protectors fail to effectively prevent abnormal noise caused by looseness, particularly in vehicle applications.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a locking mechanism is used to assemble the first member and second member, then the structural integrity is improved, but looseness and abnormal noise occur due to insufficient pressing force
Solution Approach 1:
The biasing part is pre-loaded to generate a pressing force that acts in advance to prevent looseness between the locking surfaces. This preliminary anti-action counteracts the tendency of the locking surfaces to separate under vibration or thermal expansion, thereby preventing abnormal noise before it occurs.
Solution Approach 2:
The stabilizer mechanism with the biasing part is designed to apply a continuous pressing force on the second member, which is transmitted to the locking surface through the locking mechanism. This preliminary action ensures that the locking surfaces remain firmly pressed together before any loosening can occur during operation.
2Object-affected harmful factors
If the pressing force between locking surfaces is increased to prevent looseness, then noise reduction is improved, but the device complexity increases
Solution Approach 1:
The biasing part is designed to automatically generate the necessary pressing force through its elastic deformation. The stabilizer mechanism self-regulates the pressing force applied to the locking surfaces without requiring external control systems, complex actuators, or additional power sources, thereby preventing abnormal noise while maintaining simple device architecture.
Solution Approach 2:
The pressing force is controlled by changing the physical parameters of the biasing part, such as its material properties, cross-sectional area, and length. By adjusting these parameters, the appropriate pressing force can be achieved without adding complex control mechanisms, thus reducing device complexity while effectively preventing abnormal noise.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively eliminates looseness and prevents abnormal noise in wire harnesses, even under vehicle vibrations, by applying a stabilizing force between the locking surfaces, thus enhancing the noise reduction and maintaining the structural integrity of the housing.
Implementation Method 1
a biasing part that projects from the second member to the outside, that is elastically and deformably provided along the first direction, that is elastically deformed by coming into contact with the fitting surface while the first member and the second member are locked by the locking mechanism

AI summary
A housing of a wire harness includes a first member and a second member that store therein an object to be stored; a locking mechanism that locks the first member and the second member, when a first locking surface and a second locking surface are locked to each other in a first direction; and a stabilizer mechanism that includes a fitting surface projecting from the first member to outside, and a biasing part that projects from the second member to the outside, that is elastically and deformably provided along the first direction, that is elastically deformed by coming into contact with the fitting surface while the first member and the second member are locked by the locking mechanism, and that generates biasing force for pressing the second locking surface toward the first locking surface side along the first direction.
