Vehicular Seat Wire Shield Structure for Easy Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding structures for electric wire members in vehicular seats are difficult to install and do not effectively protect the wire members, as they either require elastic expansion or have limited diameter compatibility and lack protective coverage.
Innovation Solution
A holding structure featuring a resin shield with a bending portion and a cover portion that can be locked to accommodate electric wire members of various diameters, preventing entanglement and damage by forming an integral part of the existing shield, allowing easy installation and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a holding portion with C-like shape is used to hold the electric wire member, then the wire member can be held, but the installation operation becomes difficult and the wire diameter is limited
Solution Approach 1:
The holding structure incorporates an elastic member that can dynamically adjust its shape. When the cover portion is pressed toward the main body, the elastic member deforms to allow insertion of wire members of various diameters, then returns to its original shape to securely hold the wire. This dynamic adaptation resolves the contradiction between ease of installation and adaptability to different wire diameters.
Solution Approach 2:
The holding structure changes its physical parameters (shape and size) through elastic deformation. The elastic member allows the holding structure to expand when receiving wire members of different diameters and contract to secure them. This parameter change enables the structure to accommodate various wire sizes while maintaining easy installation operations.
2Ease of operation
If a notch is used to hold the electric wire member, then the wire member can be held, but the wire member is not protected and may be entangled or damaged
Solution Approach 1:
The holding structure is segmented into a main body and a separate cover portion that can be locked to the main body. This segmentation creates an enclosed space that protects the wire member while maintaining easy installation. The cover portion can be easily attached and detached, providing protection without complicating the installation process.
Solution Approach 2:
The cover portion acts as an intermediary protective element between the wire member and the external environment. It provides a protective barrier that prevents entanglement and damage to the wire member, while the locking mechanism ensures secure attachment without complicating installation.
3Reliability
If a separate holding structure is added to hold the electric wire member, then the wire member can be held and protected, but the device complexity increases
Solution Approach 1:
The holding structure is merged with the existing shield structure. The main body and cover portion are integrated into the shield, eliminating the need for separate holding components. This merging provides wire member protection while maintaining simple construction and avoiding additional parts.
Solution Approach 2:
The shield structure is given multiple functions: it serves as both the existing shield component and as a holding structure for wire members. The main body and cover portion of the shield collectively provide both protection and holding functionality, eliminating the need for separate dedicated holding structures and reducing overall device complexity.

AI summary
A holding structure of a vehicular seat for holding an electric wire member has a shield. The shield is made of a resin and has a main body that can be integrally formed with a bending portion and a cover portion arranged on an inner side of the main body. The holding structure further includes a locking portion capable of locking the cover portion on the inner side of the main body. The holding structure is capable of accommodating awire member between the cover portion and the main body.
