Solution Overview

Problem

Existing devices for holding add-on parts on carrier parts do not allow for easy removal without tools, limiting the reuse and reconfiguration of the components.

Innovation Solution

A device featuring a U-shaped immersion clamp with resilient latching tongues and a plug-in part that allows the add-on part to be stably held in an assembly position and easily removed from the carrier part by overcoming a resistance, enabling the reuse of the immersion clamp.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a plunge-in clamp with snap-in tongues is used to hold an add-on part on a carrier part, then the add-on part is held stably in an assembly position, but the add-on part cannot be removed easily without tools

Engineering Contradiction:
Improvestable holdingVSAvoideasy removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The clamp is designed with resilient latching tongues that can dynamically change their engagement state. The tongues are spring-loaded to automatically engage with the carrier part when the plug-in part is inserted, providing stable holding. During removal, the tongues can be pushed back against their spring force to disengage, enabling easy removal without tools. This dynamic behavior allows the same clamp to provide both strong retention during use and easy release during removal.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the add-on part is firmly fixed on the carrier part, then the connection is reliable, but the immersion clamp becomes inaccessible for removal and reuse

Engineering Contradiction:
Improveconnection reliabilityVSAvoidclamp reuse
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connection system is segmented into three independent components: the immersion clamp, the plug-in part, and the carrier part. The clamp remains on the carrier part after add-on part removal, while the plug-in part (attached to the add-on part) is completely separated. This segmentation allows the clamp to be reused multiple times on the same or different carrier parts, enhancing adaptability and reducing waste.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If a resilient latching mechanism is used to enable easy removal, then tool-free removal is possible, but the device complexity increases

Engineering Contradiction:
Improvetool-free removalVSAvoidclamp structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The latching mechanism is self-actuating through spring force. The resilient tongues automatically engage with the carrier part when the plug-in part is inserted, requiring no additional fastening steps. During removal, simply pushing the plug-in part away from the clamp automatically pushes the tongues against their spring force, causing automatic disengagement. This self-service mechanism achieves tool-free operation without requiring complex control systems or multiple components.

Inventive Principle:
Principle #25Self-service

AI summary

A device for holding an add-on part on a support part in an assembly position and in a pull-out position has an insertion clip (1) and a plug-in part (22). In an assembly position of the add-on part on the support part, the plug-in part (22) is in engagement with the insertion clip (1) whereas, after the add-on part has been spaced apart from the support part, the plug-in part (22) can be disengaged from the insertion clip (1) by displacement in the direction of a foot end (4) of the insertion clip (1) and can be removed together with the add-on part, which is connected to the plug-in part (22), from the insertion clip (1) which remains in the support part.
