Hooked Clip Member With Penetrating Fixing Portion for Sewing-Free Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clip members for attaching adherends to structural components require significant workload due to the need for sewing, both for attaching the adherend to the clip member and the clip member to the structural component.
Innovation Solution
A clip member design featuring a hook engageable with the structural component's peripheral portion and a fixing portion that penetrates through the adherend to secure it, eliminating the need for sewing and mechanically determining the adherend's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adherend is attached to the clip member by sewing, then the adherend can be securely fixed to the clip member, but the workload for attachment work increases significantly
Solution Approach 1:
The invention extracts the sewing operation from the attachment process by providing a fixing portion with a penetrating tip that directly penetrates the adherend material. This eliminates the need for separate sewing operations while maintaining secure fixation, thereby resolving the contradiction between reliable attachment and reduced workload.
Solution Approach 2:
The fixing portion is designed to penetrate and secure the adherend itself during the clip member installation process. The penetrating tip automatically creates the fixation path and secures the adherend without requiring external sewing operations, enabling the system to perform the fixation function autonomously.
2Reliability
If the adherend is attached to the clip member by sewing, then the adherend can be securely fixed, but the position of the adherend cannot be precisely controlled
Solution Approach 1:
The fixing portion is pre-configured with a specific penetration path and anchoring geometry that determines the exact position where the adherend will be secured. This preliminary design of the fixation mechanism ensures precise position control before the actual attachment occurs, resolving the contradiction between secure fixation and position precision.
3Reliability
If a protrusion is formed on the peripheral portion of the structural component for attaching the adherend, then the adherend can be securely attached, but the complexity of the structural component increases
Solution Approach 1:
Instead of modifying the structural component by adding protrusions, the invention inverts the approach by providing the fixation functionality in the clip member itself through the fixing portion. The clip member's fixing portion penetrates and secures the adherend without requiring any modifications to the structural component, thereby resolving the contradiction between secure attachment and component simplicity.

AI summary
A clip member includes a hook engageable with a peripheral portion and a fixing portion configured to penetrate through an adherend to fix the adherend. The hook includes a base piece, an end piece provided at a first side with respect to the base piece; and a connecting piece connecting the base piece and the end piece. The fixing portion includes a base end continuous with the base piece and protrudes toward a second side with respect to the base piece.
