Segmented Clamp With Removable Spring Clip For Reusable Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge clamps require significant time and effort for disassembly, often resulting in damage, and their production is costly due to the need for holes or undercuts on the carrier body, which complicates manufacturing.
Innovation Solution
A clamp design featuring a connecting part with a fastening area and a receiving area for a spring clip that can be inserted non-detachably onto a rib, allowing for easy assembly and disassembly without damaging the clamp or carrier body, using a spring clip that can be easily inserted and requires a higher force for removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal spring claw is integrated into the edge clamp to hook into the rib, then the holding force on the carrier body is improved, but the disassembly time and effort increase significantly and the edge clamp may be damaged or destroyed
Solution Approach 1:
The clamp is divided into two separate functional parts: a connecting part (with fastening area) and a spring clip (with receiving area). The spring clip remains on the carrier body after disassembly, allowing the connecting part to be removed and reattached without damaging the spring clip or requiring tool assistance. This segmentation enables the holding force function to be maintained while significantly reducing disassembly time and effort.
2Reliability
If the spring clip is designed to be non-detachably attached to the projection, then the reliability of attachment is improved, but the adaptability for reuse or reattachment is reduced
Solution Approach 1:
The system is segmented into a spring clip that remains permanently attached to the carrier body and a connecting part that can be detached and reattached. This segmentation allows the spring clip to provide reliable, non-detachable attachment to the rib while the connecting part maintains adaptability for reuse. The receiving area on the connecting part can accommodate the spring clip during assembly, and the spring clip's retention in the receiving area ensures reliable connection during operation.
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
Enables quick and tool-free assembly and secure attachment to the carrier body with the option to reattach or reuse the spring clip, reducing assembly and disassembly time and costs while maintaining holding force.
Implementation Method 1
a spring clip which can be inserted into the receiving area and which, when installed, cannot be detached from a projection... The spring clip can be used detachably in the receiving area

AI summary
A clamp (21) has a connecting part (22) with a fastening area (23) for fastening at least one component and with a receiving area (24, 26) for receiving a spring clip (5), and a spring clip (5) that can be inserted into the receiving area (24, 26) in a holding manner and which, in an installed state, can be permanently attached to a smooth projection (R), wherein the spring clip (5) can be detachably inserted into the receiving area (24, 26). A method serves for the repeated and non-destructive assembly and disassembly of a clamp (1) on a carrier body (T) equipped with a projection (R). The invention is particularly applicable to motor vehicles, especially for fastening cable harnesses and hoses.
