Clip Opening Mechanism for Stable Low-Complexity Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clip expansion apparatuses require complex structures and multiple components to expand clips, making them cumbersome and costly, and often fail to stabilize the clip during expansion, leading to potential deformation or incomplete expansion.
Innovation Solution
A simplified clip expansion apparatus with a base, slide hole, main body supports, a first claw holder, and a pressing part that uses a single moving mechanism to expand the clip by pressing the second claw toward the first claw, while stabilizing the main body and allowing for easy adjustment with detachable main body supports and a magnet for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structure with multiple components is used to expand clips, then the expansion reliability is improved, but the device complexity increases
Solution Approach 1:
The clip expansion apparatus is divided into distinct functional components: a base for support, a pressing part for applying expansion force, and main body supports for stabilization. Each component performs a specific function, allowing the system to achieve reliable expansion while maintaining structural simplicity through functional segmentation rather than complex integration.
2Manufacturing precision
If multiple components are used to stabilize the clip during expansion, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The main body supports are designed to automatically position and stabilize the clip during the expansion process without requiring additional active control mechanisms. The supports passively maintain the clip in the correct position through their geometric configuration and contact points, achieving precise positioning through self-aligning features rather than complex active stabilization systems.
3Ease of manufacture
If a simplified structure is used for the clip expansion apparatus, then the ease of manufacture is improved, but the stability of the clip during expansion deteriorates
Solution Approach 1:
The base and main body supports feature locally optimized geometric configurations with specific contact points and support surfaces designed to maximize clip stability during expansion. These localized structural features provide precise positioning and stabilization without requiring complex overall device architecture, allowing simple manufacturing with high stability through carefully designed local geometries.

AI summary
A clip opening device (30) is provided with: a base (36) that supports an annular body (12) of a clip (10); a first claw holding part (38) that supports the outer surface of a first claw (14) projecting from an end of the body (12) outward in the diameter direction; and a pressing part (52) that is inserted into a slide hole (50) formed in the base (36) and that can move back and forth with respect to the first claw holding part (38) under the action of a moving mechanism (42). The pressing part (52) presses the outer surface of a second claw (16) projecting from an end of the body (12) outward in the diameter direction, and moves the second claw (16) to the first claw (14) side, when moving forth in the direction of approaching the first claw holding part (38).
