Cover Material Fixing Clip With Side Guide Lever for Wire Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover-material fixing clips face difficulties in easily introducing a wire into the hook due to insufficient elastic deformation of the guide lever, which hampers the introduction process and affects the secure fixation of the cover material.
Innovation Solution
A cover-material fixing clip design where the guide lever is connected to the side surface of the chuck, allowing for easier elastic deformation and increased length, facilitating the introduction of the wire into the hook, while the hook is connected to the bottom of the chuck for linear load transfer and secure fixation, and features like guiding projections and inclined surfaces enhance wire guidance and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guide lever is connected to the bottom of the chuck (conventional arrangement), then the structure is compact, but the guide lever length is limited and elastic deformation is difficult, making wire introduction hard
Solution Approach 1:
The guide lever is repositioned from the bottom surface to the side surface of the chuck, changing its spatial arrangement. This dimensional shift allows the guide lever to extend along the longitudinal direction of the chuck, increasing its effective length and ease of deformation without increasing overall device complexity
2Ease of operation
If the tip ends of the hook and guide lever are bent to widen the gap, then wire introduction is facilitated, but the gap-widening movement is hampered when tip ends contact the cushion material
Solution Approach 1:
By connecting the guide lever to the side surface rather than the bottom, the lever gains additional deformation space in the longitudinal direction. This allows the gap-widening movement to occur without the tip ends contacting the cushion material, resolving the conflict between ease of wire introduction and fixation reliability
3Ease of operation
If the guide lever is made longer to improve deformation ease, then wire introduction becomes easier, but the connection point on the bottom surface limits the achievable length
Solution Approach 1:
The guide lever is relocated from the bottom surface to the side surface of the chuck, allowing it to extend along the longitudinal axis. This repositioning enables the guide lever to achieve greater length without interfering with the chuck's bottom surface connections, thereby improving elastic deformability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables easy and reliable introduction of the wire into the hook, ensuring secure fixation of the cover material by enhancing elastic deformation and load transfer, preventing wire drop-off and erroneous entry into dents, and allowing for adjustable locking without the need for elongated holes.
Implementation Method 1
the guide lever is elastically deformed to be apart from the hook to allow the wire to pass through a gap between the guide lever and the hook

AI summary
A cover-material fixing clip includes: a chuck that pinches a locking hem formed on a back surface of a cover material; a hook that locks a wire provided in a groove of a cushion material; and a guide lever that is provided facing an opening of the hook. A proximal end of the hook is connected to a bottom of the chuck opposite to the cover material. The guide lever is connected to a side surface of the chuck.
