Integrated Bracket for Vehicle Cable Harness Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness fixing structures are inadequate for securing multiple cables of varying lengths and diameters, leading to potential damage and disruption of data transmission due to inadequate retention and susceptibility to mechanical and environmental stresses.
Innovation Solution
An integrated bracket design featuring a first plate with an opening for fastening, an inlet gate, a second angled plate, a protection shield, and exit gates with extending arms, which securely retains multiple cables and protects them from environmental elements, allowing for secure attachment to a vehicle body while resisting mechanical and environmental stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single retainer is used to secure cables, then the structure is simple, but it cannot adequately secure multiple cables of varying lengths and diameters
Solution Approach 1:
The bracket is divided into multiple functional segments: a first plate for mounting, a second plate for cable retention, multiple retainers positioned at different locations, and a protection shield. Each segment performs a specific function, allowing the structure to securely hold multiple cables of varying lengths and diameters while maintaining overall structural integrity.
Solution Approach 2:
The bracket is designed as a multi-functional component that can secure multiple cables simultaneously, provide mechanical protection through the protection shield, and offer mounting attachment points. The multiple retainers can accommodate cables of different sizes, making the single bracket structure universally applicable to various cable configurations.
2Device complexity
If a single retainer is provided on the fixing structure, then the structure remains simple, but long cables cannot be adequately secured causing them to waggle and pose potential for damage
Solution Approach 1:
Multiple retainers are distributed across the bracket structure at different positions and orientations. This segmentation allows long cables to be secured at multiple points along their length, preventing excessive movement and reducing mechanical stress, while keeping each individual retainer relatively simple in design.
Solution Approach 2:
The retainers are positioned in different spatial dimensions and orientations on the bracket, providing multi-directional support for cables. This dimensional distribution of retention points effectively secures long cables against wagging and mechanical stress without requiring overly complex individual retainers.
3Reliability
If multiple retainers are added to secure different cables, then cable retention improves, but the structure becomes more complex
Solution Approach 1:
Multiple retainers, a protection shield, and mounting plates are merged into a single integrated bracket assembly. This combining of multiple functional elements into one unified structure provides reliable multi-cable retention capability while avoiding the complexity of assembling separate components, as the entire structure functions as a single bracket unit.
4Device complexity
If cables are left unsecured, then the structure remains simple, but cables are susceptible to mechanical and environmental stresses causing damage and disruption of data transmission
Solution Approach 1:
The bracket structure is pre-configured with multiple retainers and a protection shield in strategic positions before cables are installed. This preliminary arrangement of protective and retention elements ensures that cables are immediately secured and protected upon installation, preventing exposure to mechanical and environmental stresses from the outset.
Solution Approach 2:
The protection shield acts as an intermediary element between the cables and harmful environmental factors. It provides a physical barrier that shields cables from dust, moisture, and other environmental contaminants, while the retainers serve as intermediaries that distribute and reduce mechanical stresses on the cables.

AI summary
Methods and systems are provided for an integrated bracket for securely retaining one or more cables of a harness to a vehicle body. In one example design, the integrated bracket may include a first plate with an opening to receive a fastener to securely attach the bracket to the vehicle body; an inlet gate coupled to the first plate; a second plate coupled and angled to the first plate; a protection shield extending from the first plate; and an exit gate attached to the second plate, each gate having an extending arm pair. In one example, by routing the cables of the harness through the bracket, and securely retaining the cables using clamps on the inlet and outlet gates, the bracket provides a simplified system for securely attaching the harness to the engine, thereby minimizing unnecessary cable movement, while reducing stresses exerted on the harness.
