Vehicle Seat Cover Segmentation for Cushion Pad Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat covers face difficulties in attachment due to the floating lower portion cover, which cannot be stabilized by the cushion pad due to the space between the lower cover and the cushion pad when both ends are linked.
Innovation Solution
A vehicle seat design with a cushion pad that includes an upper and lower portion pad, where the cover features an upper portion cover, a front and rear portion cover, and link portions that detachably link the rear edge of the front cover with the front edge of the rear cover, contacting the lower portion pad for stability, and side covers that link through second and third link portions, allowing easy attachment and detachment without interfering with the support leg.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the lower portion cover both ends are mutually linked, then the cover structure is complete, but the lower portion cover floats and cannot be stabilized due to the space between the lower portion cover and the cushion pad
Solution Approach 1:
The lower portion cover is divided into front and rear sections that are detachably linked rather than continuously connected. This segmentation allows the link portion to contact the cushion pad for stabilization while maintaining ease of attachment and detachment.
Solution Approach 2:
The cushion pad acts as an intermediary between the lower portion cover and the floor, providing a contact surface for the link portion. This intermediary enables the floating cover to be stabilized without requiring direct contact with the floor or additional reinforcement structures.
2Ease of operation
If the cover is designed with detachable link portions, then the cover can be easily attached and detached, but the structure becomes more complex
Solution Approach 1:
The cover is segmented into upper and lower portions with detachable link portions connecting the rear edge of the front portion cover to the front edge of the rear portion cover. This segmentation enables easy attachment and detachment while using simple link mechanisms rather than complex fastening systems.
Solution Approach 2:
The link portions are designed to be detachable rather than fixed, allowing the cover structure to transition between assembled and disassembled states. This dynamic design simplifies the attachment process while maintaining structural integrity when assembled.
3Ease of manufacture
If the lower portion cover is formed as a continuous piece, then the manufacturing is simpler, but it cannot be easily detached and reattached
Solution Approach 1:
The lower portion cover is manufactured in separate front and rear sections that are later assembled through detachable link portions. This segmentation increases manufacturing steps but enables easy detachment and reattachment, prioritizing operational ease over manufacturing simplicity.
Solution Approach 2:
The front and rear portion covers are prepared separately in advance with linking portions ready for assembly. This preliminary preparation of separate components facilitates both manufacturing and subsequent easy attachment/detachment operations.

AI summary
Provided is a vehicle seat (1) capable of facilitating the mounting of a cover (30). The cover (30) of a seat cushion (2) is configured such that a upper portion cover (31) is disposed on the upper surface side of the seat cushion (2), a front portion cover (33) extends from the front edge of the upper portion cover (31) to the rear surface side of the seat cushion (2), and a rear portion cover (34) extends from the rear edge of the upper portion cover (31) to the rear surface side of the seat cushion (2). A first link portion (44) which detachably couples the rear edge of the front portion cover (33) and the front edge of the rear portion cover (34) to each other contacts a lower portion pad (22) of a cushion pad (20).
