Arcuate Clip Forceps for Angular Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clip application forceps can only grip clips in a single angular position, making application and removal difficult, especially when the forceps are not aligned with the clip's longitudinal direction.
Innovation Solution
The forceps feature arcuate depressions or projections on their sides, extending at least 180° to 270°, allowing the clip to be gripped at any angular position, with widened regions and curved geometries matching the clip's design for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the forceps have a single angular grip position, then the structure is simple, but the ease of operation deteriorates when alignment with the clip's longitudinal direction is not possible
Solution Approach 1:
The forceps leg is designed with an arcuate depression extending along a curved path (at least 180°, preferably 270°) instead of a straight linear grip position. This curvature allows the clip to be engaged at multiple angular positions while maintaining a relatively simple single-piece forceps structure, resolving the contradiction between operational ease and device complexity.
2Adaptability or versatility
If the depression extends along an arcuate curve, then the adaptability improves for different angular positions, but the manufacturing precision requirements increase
Solution Approach 1:
The arcuate depression geometry is optimized with specific parameters (curvature radius, arc angle of at least 180°, width variations along the arc) that allow manufacturing using standard precision techniques. The curved path is designed to accommodate natural variations in clip positioning while maintaining reliable engagement, balancing adaptability with manufacturability.
3Stability of the object's composition
If the forceps legs are widened like a plate, then the stability of engagement improves, but the volume of the forceps increases
Solution Approach 1:
The forceps legs are widened only in the specific region where the arcuate depression is located, rather than increasing the overall volume of the entire forceps. This localized widening provides stable engagement for the clip at the critical grip position while keeping the rest of the forceps compact and manageable.

AI summary
An applying forceps for a clip comprises two forceps legs which can be pivoted relative to each other and comprise, on their sides facing each other or facing away from each other, each a depression or a projection for receiving a clip, wherein the depression or projection extends along an arcuate curve.
