Vehicle Roof Lining Integrated Wire Holder Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle interior components, there is a need to reduce the number of parts required for attaching electric components while ensuring that wire harnesses are properly held and accessible during assembly, as separate brackets can lead to misplacement of wires and connectors.
Innovation Solution
A vehicle interior component with a built-in wire holder that temporarily holds the end section of electric wires and connectors, featuring a resilient base section, free end section, and middle section, which defines a space to securely position the wire and connector, reducing the need for extra parts and preventing displacement during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate bracket is used to hold the wire harness, then the wire harness can be held at a proper position, but the number of parts increases
Solution Approach 1:
The wire holder is integrated into the roof lining as a unitary structure, merging the function of holding wire harnesses with the roof lining component itself. This eliminates the need for separate brackets while maintaining proper wire positioning during assembly
Solution Approach 2:
The roof lining is designed to serve multiple functions: it provides interior finishing and simultaneously acts as a wire holder through its integrated structure with the hole edge and resilient sections, eliminating the need for dedicated wire holding components
2Device complexity
If the bracket is omitted to reduce parts, then the number of parts decreases, but the wire harness may be misplaced during fixing
Solution Approach 1:
The wire holder structure is pre-formed as part of the roof lining, with the hole edge and resilient sections already configured to hold wire harnesses in the correct position before assembly begins, preventing misplacement during the fixing process
Solution Approach 2:
The wire holding function is merged into the roof lining structure itself, ensuring that wire harness positioning capability is built-in rather than added separately, thus reducing parts while maintaining reliability
3Ease of operation
If the wire holder is made resilient to allow rotation, then the electric component can be easily inserted, but the wire holder may move out of position
Solution Approach 1:
The wire holder incorporates resilient sections that allow dynamic movement and rotation during assembly operations, enabling the holder to flex out of the way when needed while maintaining its positioning function during normal operation
Solution Approach 2:
The resilient sections change their mechanical properties (flexibility and rotation capability) temporarily during insertion operations, then return to their original rigid positioning state, allowing both ease of operation and positioning reliability

Function Achieved in This Case
This solution reduces the number of parts needed and minimizes the likelihood of wire and connector displacement, ensuring proper positioning and easy access for connection, thereby enhancing assembly efficiency and reducing the complexity of the vehicle interior component installation process.
Implementation Method 1
The base section extends from a first section of a hole edge of the through hole toward an inner side of the through hole and has resilience

AI summary
A vehicle interior component includes: a body including a through hole, a first surface opposed to a vehicle body panel, and a second surface opposite from the first surface; and a wire holder holding an end section of an electric wire connected with a wire-side connector. The wire holder includes: a base section extending from a first section of a hole edge of the through hole toward an inner side of the through hole and having resilience; a free end section including an end surface opposed to a second section of the hole edge; and a meddle section. The base section, the free end section, the middle section, and the first section define a space with a dimension greater than a diameter of the end section and less than the wire-side connector to hold the end section in the space and the wire-side connector closer to the second surface.
