Clamp With Segmented Padded Jaws For Curved Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamps are inconvenient to use, particularly when clamping handles of cutting implements during sharpening or sharpness testing, as they often fail to securely grip handles of varying shapes and sizes.
Innovation Solution
A clamp with a first jaw and a second jaw that can swing relative to each other, featuring padded parts with inwardly angled sides and ridges for secure gripping, a spring-loaded hinge mechanism, and a latch system with teeth for locking, designed to accommodate both straight and curved handles, and compatible with blade testing or sharpening machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional clamps are used to clamp handles of cutting implements, then the clamping action is simple, but the grip is insecure on handles of varying shapes and sizes
Solution Approach 1:
The jaw surfaces are divided into multiple padded parts with different geometries (flat outer parts and recessed central part) to match different handle shapes. Each local area of the jaw is optimized for specific handle types, providing secure contact regardless of whether the handle is straight or curved.
Solution Approach 2:
The clamp jaw is designed with multiple padded parts that can accommodate various handle shapes (straight handles, curved handles, scissors with hooks) using the same clamping mechanism. This multi-functional design allows a single clamp to securely grip diverse handle types without requiring multiple specialized tools.
2Adaptability or versatility
If the clamp is designed to accommodate various handle shapes, then versatility is improved, but device complexity increases
Solution Approach 1:
The jaw is segmented into multiple distinct padded parts (first outer padded part, second outer padded part, and central padded part) rather than using a single continuous surface. This segmentation allows each part to be optimized for specific handle shapes while maintaining a relatively simple overall jaw structure that can be manufactured as a single component.

Function Achieved in This Case
The clamp provides secure and versatile handling of handles during sharpening or testing, preventing rotation and movement, while allowing easy attachment to machines, thus enhancing user convenience and adaptability.
Implementation Method 1
the hinge mechanism is spring loaded
Implementation Method 2
padded parts with inwardly angled sides adapted for gripping the handle

AI summary
A clamp suitable for clamping a handle from which a blade extends or a pair of scissors when the blade is being tested or sharpened. The clamp includes a first jaw, a second jaw and a releasable lock if the form of a latch and teeth. At least one of the jaws are able to swing with respect to the other jaw through a hinge mechanism. The first jaw comprises two outer padded parts and a central padded part. The outer and central padded parts are aligned. The central padded part is recessed such that a curved handle or pair of scissors can lay against all three padded parts when clamped. If a straight handle is clamped, the handle only contacts the outer padded parts. The second jaw also comprises padded parts which are inwardly angled for gripping.
