Compression Tool Work Head for Variable-Size Object Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression tools face issues with compatibility of abutment jaw shapes to objects of varying sizes, leading to incorrect positioning, visibility obstruction, and inefficient energy consumption due to uniform compression force application.
Innovation Solution
The tool features an abutment jaw with an arched abutment seat and a compression jaw with a convex punch surface, both designed to accommodate objects of different sizes with improved visibility and positioning, and a wavy compression pattern that reduces energy consumption by varying force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the thickness of the abutment seat is dimensioned for the largest object size, then large objects can be compressed properly, but small objects are obscured from user view and cannot be positioned correctly
Solution Approach 1:
The abutment seat is divided into multiple zones with different thicknesses: a first zone with greater thickness for large objects and a second zone with reduced thickness for small objects. This segmentation allows each zone to be optimized for its specific object size range, enabling proper compression of large objects while maintaining visibility and positioning capability for small objects.
Solution Approach 2:
Different regions of the abutment seat are given different local properties (thickness values) according to the specific requirements of objects to be compressed. The first zone has increased thickness locally to accommodate large objects, while the second zone has reduced thickness locally to allow user visibility and correct positioning of small objects.
2Device complexity
If a simple curved abutment seat shape is used, then the structure is simple, but compression force is applied uniformly which consumes excessive energy
Solution Approach 1:
The abutment seat incorporates zones with different curvature radii: a first zone with a first curvature radius and a second zone with a second curvature radius that is at least 1.5 times greater. This creates non-uniform compression force distribution, concentrating force where needed and reducing it in other areas, thereby lowering overall energy consumption while maintaining compression effectiveness.
3Productivity
If the abutment seat thickness is increased to cover the entire object length, then compression can be performed in one operation, but the object cannot be positioned correctly in the seat
Solution Approach 1:
The abutment seat is segmented into a first zone with greater thickness and a second zone with reduced thickness. This segmentation enables the seat to accommodate objects of varying lengths while maintaining positioning accuracy, as the reduced thickness zone does not obscure the object from user view.
Solution Approach 2:
The thickness parameter of the abutment seat is varied across different zones rather than being uniform. By changing the thickness parameter locally (greater in the first zone, reduced in the second zone), the seat can perform single-operation compression for various object sizes while allowing correct positioning.

AI summary
A work head (1) for or of a compression tool (2) comprises a compression jaw (6) and an abutment jaw (3) forming an arched abutment surface (7) having a longitudinal extension (8) arched in a hypothetical arc plane (9) orthogonal to an insertion direction (10) of the object (5) into the abutment seat (4), wherein the longitudinal extension (8) has a first side segment (11), a second side segment (12) opposite to the first side segment (11), and an apex segment (13) in the shape of a neck extending between the first side segment (11) and the second side segment (12), an abutment width (14) measurable in the insertion direction (10) and orthogonal to the arc plane (9). The abutment width (14) decreases from a first base width (15) of the first side segment (11) to an apex width (16) of the apex segment (13) and wherein the abutment width (14) decreases from a second base width (17) of the second side segment (12) to the apex width (16) of the apex segment (13).
