Solution Overview
Problem
Existing cover-material fixing tools face challenges in securely attaching the cover-material to a wire in a cushion material, leading to issues with wrinkles and unevenness due to lack of precise positioning and flexibility, especially when the cover-material does not conform to the cushion material's shape after cutting or stitching.
Innovation Solution
A cover-material fixing tool with a flexible tape member and clip locking member that includes stoppers and locking recess portions along its length, allowing for adjustable positioning and secure attachment to the wire, while accommodating shape deviations and providing flexibility to conform to curved surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover-material fixing end member does not have a measure to longitudinally lock the clips, then the clips can freely slide on the cover-material fixing end member, but it becomes difficult to lock the clips at a desired location and workability deteriorates
Solution Approach 1:
The invention introduces stoppers at specific positions along the cover-material fixing end member to create discrete positioning points. This changes the continuous sliding parameter to a discrete positioning system, allowing clips to be locked at desired locations while maintaining ease of operation.
Solution Approach 2:
The stoppers act as intermediary elements between the clips and the cover-material fixing end member. These stoppers provide physical contact points that enable precise positioning without requiring complex locking mechanisms, thus maintaining operational simplicity.
2Manufacturing precision
If the wire has a part covered with cushion material and the exposed part is short, then the clip cannot be freely adjusted in position, but internal stress cannot be released causing wrinkles on the cover-material
Solution Approach 1:
The invention provides multiple stoppers at different positions along the cover-material fixing end member, creating discrete positioning options. This allows the clip to be positioned at various locations to accommodate varying wire exposure lengths while maintaining precise positioning through the stopper-clip interaction.
Solution Approach 2:
The invention enables dynamic positioning of clips along the cover-material fixing end member by providing multiple stoppers at different locations. This dynamic adjustment capability allows the system to adapt to different wire exposure conditions and release internal stress appropriately.
3Stability of the object's composition
If the cover-material does not conform to the cushion material shape due to cutting or stitching deviations, then internal stress occurs, but without clip position adjustment capability, wrinkles occur on the cover-material
Solution Approach 1:
The invention introduces multiple stoppers at different positions to enable discrete position adjustment of clips. This parameter change allows the system to compensate for shape deviations between cover-material and cushion material by positioning clips at optimal locations, thereby maintaining surface flatness.
Solution Approach 2:
The stoppers provide positional feedback points that guide the operator in positioning clips at appropriate locations to accommodate shape deviations. This feedback mechanism helps maintain proper tension and flatness of the cover-material surface.

AI summary
There is provided a cover-material fixing tool. A cover-material fixing end member is configured to be attached on a cover-material. A clip is configured to be attached on a cover-material fixing end member. The cover-material fixing end member includes a tape member, a clip locking member, and a plurality of stoppers. The clip includes a locking portion for holding the clip locking member to allow the clip locking member to move in a longitudinal direction, and a locking protrusion protruding toward the clip locking member and configured to abut against the stoppers. The clip is movable between the adjacent stoppers to allow position adjustment thereof.
