Wire Harness Fixing Intervals to Suppress Fluttering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harnesses face challenges in easily fixing wire-like transmission members to base members, particularly in reducing fluttering and minimizing the number of fixing positions while maintaining secure attachment.
Innovation Solution
The solution involves using a combination of first and second wire-like transmission members with different bending and deformation properties, where the first member is fixed at a larger interval and the second member at a smaller interval, allowing for reduced fixing positions while suppressing fluttering, and optionally incorporating a third member with intermediate deformation properties for finer interval settings.

Engineering Contradiction Analysis
1Ease of operation
If wire-like transmission members are fixed at constant intervals, then the fixing process is simple, but fluttering cannot be effectively suppressed and the number of fixing positions increases
Solution Approach 1:
The patent applies different fixing intervals to different types of wire-like transmission members based on their specific characteristics. Stiffer wires (first type) are fixed at larger intervals while more flexible wires (second type) are fixed at smaller intervals. This local differentiation allows each wire type to be fixed with appropriate spacing, suppressing fluttering effectively while reducing the overall number of fixing positions compared to a uniform fine-spacing approach.
2Reliability
If fixing intervals are reduced to suppress fluttering, then stability improves, but the number of fixing positions increases
Solution Approach 1:
The patent differentiates fixing intervals according to wire stiffness characteristics. The first wire-like transmission member with higher stiffness is fixed at larger intervals, while the second wire-like transmission member with lower stiffness is fixed at smaller intervals. This localized adaptation allows effective fluttering suppression for each wire type without requiring uniformly small intervals across all wires, thereby reducing the total number of fixing positions.
Solution Approach 2:
The patent segments the wire-like transmission members into at least two types based on their bending and deformation characteristics. This segmentation allows the application of different fixing strategies (different intervals) to different segments, optimizing both fluttering suppression and the number of fixing positions for each segment rather than applying a one-size-fits-all approach.
3Ease of manufacture
If uniform fixing intervals are used for all wire-like members, then the fixing process is standardized, but it does not account for different bending and deformation properties
Solution Approach 1:
The patent implements local quality by assigning different fixing intervals to different wire types based on their mechanical properties. The first wire-like transmission member (stiffer) uses a first fixing interval while the second wire-like transmission member (more flexible) uses a second fixing interval. This approach maintains standardization within each wire type group while adapting to the specific characteristics of different wire types.
Solution Approach 2:
The patent changes the fixing interval parameter according to the wire type. By identifying at least two types of wire-like transmission members with different bending and deformation properties, the patent applies different interval parameters (first interval for first type, second interval for second type) to optimize the fixing process for each wire type's mechanical characteristics.
