Wire Harness Tie Strap Cradle for Fast, Vibration-Resistant Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harnesses lack efficient and standardized methods for securing multiple cables or wires, leading to issues with vibrations, abrasions, and moisture exposure, which increase installation time and complexity.
Innovation Solution
A system comprising a body with a channel and a cradle that secures a wire harness using a tie strap, where the tie strap extends through an opening in the cradle and around the channel, with a retention mechanism to maintain the head of the tie strap in a single orientation, ensuring secure and efficient installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wire harnesses are secured using traditional methods, then installation flexibility is maintained, but installation time increases and standardization is lost
Solution Approach 1:
The securing system is divided into distinct functional components: a channel structure for positioning the wire harness, a cradle for securing the tie strap head, and a tie strap for fastening. This segmentation allows each component to be optimized independently and facilitates standardized, repeatable installation procedures that reduce time and complexity
Solution Approach 2:
The channel and cradle are pre-configured in specific geometric relationships before installation. The channel is formed with specific dimensions and the cradle is positioned at predetermined locations, allowing installers to simply thread the tie strap through pre-defined paths without requiring complex alignment or measurement during installation
2Reliability
If wire harnesses are bound together by durable material, then protection against vibrations and abrasions is improved, but installation complexity increases
Solution Approach 1:
The tie strap serves multiple functions simultaneously: it binds the wire harness together for protection, secures the harness to the channel structure for vibration resistance, and provides a standardized fastening mechanism that simplifies installation. This multi-functionality eliminates the need for separate protective materials and mounting hardware
Solution Approach 2:
The channel structure itself provides the mounting surface and positioning features needed for secure installation. The cradle is integrated into the channel geometry, and the tie strap automatically engages with both the wire harness and the channel structure through its routing path, eliminating the need for additional fasteners or complex mounting procedures
3Device complexity
If a cradle is integrated into the channel structure, then device complexity is reduced, but installation flexibility is worsened
Solution Approach 1:
The cradle is integrated only at specific locations along the channel where wire harness securing is required, rather than making the entire channel structure complex. The cradle geometry is simplified to provide only the essential function of holding the tie strap head, while the rest of the channel maintains its simple, flexible form factor that can be easily installed in various configurations

AI summary
A system for securing a wire harness with a tie strap. The system includes: a body defining a channel configured to receive the wire harness; and a cradle adjacent to the channel, the cradle configured to hold a head of the tie strap, the cradle defining an opening for the tie strap to pass through. The wire harness is secured within the channel by the tie strap extending out of the cradle through the opening, under the body, across the channel, and into cooperation with the head seated in the cradle.
