Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hammers and mallets with rigid tapping faces generate instant rebound reaction forces, leading to reduced tapping efficiency, discomfort, and increased noise, affecting the smoothness and control of operations in industrial, medical, and golfing applications.
Innovation Solution
A force-limiting and damping device with an elastic element mounted between the tapping segment and the body, providing a damping effect by converting reaction forces into potential energy, thus increasing the contacting time and reducing noise and discomfort, featuring an adjustable locking mechanism to alter elastic tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid tapping face is used, then the structure is simple and strong, but an instant rebound reaction force is generated causing discomfort and reduced control
Solution Approach 1:
The patent changes the physical state of the tapping face from rigid to elastic by introducing an elastic element. This allows the tapping face to deform elastically during impact, absorbing rebound energy and reducing the instant reaction force that causes discomfort and reduces control. The elastic deformation parameter enables the system to transition between rigid and compliant states.
Solution Approach 2:
The patent creates a composite structure combining the body (rigid component) with an elastic element (flexible component). This composite design allows the tapping face to exhibit both strength from the rigid body and comfort from the elastic element, resolving the contradiction between structural strength and operational comfort.
2Device complexity
If a rigid tapping face is used, then the structure is simple, but the contacting time is short reducing tapping efficiency
Solution Approach 1:
The patent introduces elastic deformation as a new parameter that extends the contact duration. During impact, the elastic element compresses and then rebounds, naturally extending the contacting time between the tapping face and the workpiece. This prolonged contact time allows for more effective energy transfer and improves tapping efficiency without significantly complicating the device structure.
3Device complexity
If a rigid tapping face is used, then the device is simple, but noise and energy loss increase
Solution Approach 1:
The patent converts the harmful instant rebound reaction force into a beneficial damping effect. The elastic element captures the rebound energy through elastic deformation and dissipates it gradually, transforming the harmful noise and energy loss into useful damping that reduces noise and improves energy utilization. The rebound force that previously caused harm now serves to extend contact time and reduce noise.

AI summary
A force-limiting and damping device has a body (10), a tapping element (20), and an elastic element (30D). The body (10) has a connecting segment (11D) and a holding segment (12). The connecting segment (11D) has a mounting hole (111D). The tapping element (20D) is connected to the body (10) to move relative to the connecting segment (11D). The elastic element (30D) is mounted between the tapping element (20D) and the connecting segment (11D). The structural relationship between the connecting segment (11D), the tapping element (20D), and the elastic element (30D) may provide a delayed rebound and damping effect to the reaction force, and the applied force is continuously transferred to a tapping object to reduce noise and the loss of energy.
