Sliding Seat Wiring Harness Module With Concealed FFC Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring harnesses between a vehicle body and a sliding seat are aesthetically unpleasing, pose a risk of foot entrapment, and are prone to damage due to exposure.
Innovation Solution
A wiring harness module with a sliding casing, a connector holder, a sliding connector, a joint connector, and a flat flexible cable (FFC) that absorbs the sliding motion of the connector holder, ensuring electrical connection stability and hiding the wiring from exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple wiring harness with exposed electric wires is used to connect the seat and vehicle body, then electrical connection is achieved, but aesthetic appearance deteriorates and safety risk increases due to foot entrapment
Solution Approach 1:
The wiring harness is nested inside a sliding casing that moves with the seat, concealing the electric wires within the casing structure. This nesting approach eliminates exposed wires while maintaining electrical connectivity, resolving both the aesthetic appearance issue and foot entrapment risk.
Solution Approach 2:
The wiring harness system incorporates a sliding casing that dynamically moves forward and backward along with the seat position changes. This dynamic structure allows the wiring harness to remain concealed during seat movement, preventing foot entrapment while maintaining aesthetic appearance throughout the sliding range.
2Device complexity
If electric wires are exposed between vehicle body and seat, then electrical connection is simplified, but durability deteriorates due to wire damage risk
Solution Approach 1:
The electric wires are nested within the sliding casing, protecting them from external damage. This enclosure structure prevents wire exposure to harsh environmental conditions and mechanical damage risks, significantly improving wiring harness durability while maintaining manageable complexity through modular design.
3Object-affected harmful factors
If a wiring harness module is introduced to conceal wires, then aesthetic appearance and safety improve, but device complexity increases
Solution Approach 1:
The sliding casing serves multiple functions: it conceals the wiring harness for aesthetic purposes, prevents foot entrapment for safety, and protects wires from damage for durability. This multi-functionality approach improves appearance and safety without proportionally increasing complexity, as a single structure achieves multiple goals.
Solution Approach 2:
The sliding casing is designed to move dynamically with the seat, integrating the wiring protection function into the existing seat movement mechanism. This dynamic integration avoids adding separate complex protection structures, maintaining reasonable device complexity while achieving aesthetic and safety improvements.
4Ease of manufacture
If the connector holder slides freely without guidance, then ease of installation improves, but stability deteriorates due to unstable electrical connection
Solution Approach 1:
The guide holes are pre-formed in the sliding casing to provide predetermined sliding paths for the connector holder. This preliminary structural preparation ensures stable electrical connection during seat movement while maintaining ease of installation, as the guide features are integrated into the casing design rather than requiring separate alignment procedures.
