Harness Protector for Planar Wire Harness Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of electronic components on vehicles leads to larger wire harness diameters, making it difficult to bend and manage wire harnesses, which results in poor wiring operability and space inefficiency, as conventional band clamps cannot form wire harnesses into a planar shape or securely anchor them against axial loads.
Innovation Solution
A harness protector with a tabular-shaped bottom-plate and rotatable holding plates that crush the wire harness into an oblate cross-section, combined with tying bands and movement restraint projections, allows for easy formation and maintenance of a planar shape, improved anchoring, and reduced space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of electronic components is increased, then the functionality is improved, but the wire harness diameter is enlarged making it difficult to bend and manage
Solution Approach 1:
The patent changes the cross-sectional shape parameter of the wire harness from circular to oblate (flattened) by applying crushing force through the holding plate section. This parameter change allows the wire harness to be bent with a smaller radius and improves wiring operability while accommodating the increased number of electronic components
2Quantity of substance
If the wire harness diameter is enlarged, then more wires can be accommodated, but the bending radius becomes larger requiring more wiring space
Solution Approach 1:
The patent transforms the wire harness from a circular cross-section to an oblate (flattened) cross-section by applying force in the vertical dimension through the holding plate section. This dimensional change allows the wire harness to fit into tighter spaces and reduces the area required for wiring while maintaining the quantity of wires
3Reliability
If a conventional band clamp is used, then the wire harness can be anchored, but it cannot form the wire harness into a planar shape or securely anchor it against axial loads
Solution Approach 1:
The patent merges multiple functions into a single holding plate section: it crushes the wire harness into an oblate shape, maintains the planar configuration, and provides anchoring capability against axial loads through movement restraint projections. This integrated structure resolves the limitation of conventional band clamps that could only perform one function
4Ease of operation
If the wire harness is made planar, then wiring operability is improved and space is saved, but it requires secure anchoring to maintain the shape under load
Solution Approach 1:
The patent applies preliminary crushing action through the holding plate section to form the wire harness into an oblate planar shape before anchoring. The movement restraint projections are pre-configured to prevent axial movement, ensuring the planar shape is maintained under load without requiring additional anchoring measures

AI summary
Provided is a harness protector, wherein a wire harness can easily be formed into a planar shape (with an oblate cross section), and maintained in that state. The harness protector is provided with: a protector body (3) further provided with a roughly tabular-shaped bottom-plate section (11) onto which a wire harness (9) is to be placed, and a holding plate section (15) that is integrally formed on one side of the bottom-plate section (11) in pivotable state, and crushes the wire harness (9) into an oblate cross-section shape, along with the bottom-plate section (11); and tying bands (5) that anchor the holding plate section (15) onto the bottom-plate section (11), in a state of having the holding plate section (15) crushing the wire harness (9) into an oblate cross-section shape.
