Vehicle Interior Skin Joint Layout for Hidden Sensor Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interior members in vehicles face issues with redundant wiring that leads to decreased operability and impaired designability due to the wire being visible and the cushion layer absorbing pressing force, affecting the tactile feel and appearance.
Innovation Solution
The interior member is designed with a first and second skin material, where the wiring is routed through a joint between these materials, preventing redundancy and ensuring the wiring is hidden, while the sensor is positioned directly behind the skin material to improve operability and designability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wire is routed to bypass the outer edge of the lid, then the wire can be connected to the switch, but the routing length increases and the wire becomes redundant
Solution Approach 1:
The skin material is divided into a front side portion and a back side portion that are joined together. The wire is routed through the joined portion of these segments, allowing the wire to pass through a narrow space rather than bypassing the outer edge, thus reducing wiring redundancy while maintaining connectivity.
2Ease of manufacture
If the switch is disposed on the back side of the cushion layer, then the wire can be routed through the skin material, but the pressing force is absorbed by the cushion layer and operability deteriorates
Solution Approach 1:
The skin material is segmented into front and back portions joined at the wire routing path. This segmentation allows the wire to pass through the joined portion without requiring the switch to be positioned behind the cushion layer, enabling the switch to be placed on the front side where pressing force transmission is effective.
Solution Approach 2:
The wire routing path is moved to a different spatial dimension by utilizing the joined portion of the segmented skin material. This dimensional change allows the wire to pass through a narrow space without interfering with the switch position, enabling optimal switch placement for operability.
3Ease of operation
If the switch is disposed on the front side of the cushion layer to improve operability, then pressing force is transmitted effectively, but the wire must also be on the front side and becomes visible through the surface layer
Solution Approach 1:
The skin material is divided into front and back side portions that are joined together. The wire is routed through this joined portion, which is positioned such that the wire remains hidden from the front view while the switch on the front side maintains good operability.
Solution Approach 2:
The joined portion of the segmented skin material serves as an intermediary structure that allows the wire to pass through hidden from the front, while still enabling the wire to connect to the switch positioned on the front side for good operability.
4Shape
If the wire is hidden by routing it through the skin material, then appearance is improved, but the wire may still be detected by tactile sense
Solution Approach 1:
The skin material is segmented into front and back portions joined together, creating a narrow routing path for the wire. This segmentation allows the wire to be concealed within the joined structure, reducing both visual and tactile detectability while maintaining appearance quality.

AI summary
An interior member includes a first skin material, a second skin material, and transducers. The first skin material includes a first exposed part exposed to a cabin interior, and a first embedded part embedded on a cabin exterior side from the first exposed part. The second skin material includes a second exposed part exposed to the cabin interior and adjacent to the first exposed part, and a second embedded part embedded on the cabin exterior side from the second exposed part and joined to the first embedded part. The transducers each include a main body arranged directly back of the first exposed part, and a wiring part disposed directly back of at least the first embedded part and electrically connected to the main body. An end of each wiring part is disposed on the cabin exterior side of the first embedded part.
