Shock Absorbing Hammer Head With Mixed Pellet Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock absorbing hammers with rigid pellets suffer from unpredictable rebound, material damage, reduced durability, and increased risk of hand injury due to unstable pellet movement and lack of effective shock absorption.
Innovation Solution
A shock absorbing hammer design featuring two separated housings filled with a mixture of rigid and soft pellets, where the rigid pellets are dispersed by the soft pellets to absorb impact, reducing rebound and enhancing durability through a rabbet joint mechanism for stable pellet distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid pellets are used in the head tube, then shock absorbing capability is improved, but pellet rebound and instability increase causing hand injury risk
Solution Approach 1:
The patent uses a composite material system consisting of rigid pellets (steel or iron) combined with soft pellets (rubber or plastic) in a 1:1 ratio. The rigid pellets provide shock absorbing capability while the soft pellets dampen rebound and stabilize movement, resolving the contradiction between shock absorption and injury prevention.
Solution Approach 2:
The patent changes the physical state and material properties by introducing soft pellets with different elasticity and density characteristics compared to rigid pellets alone. This parameter change in material composition allows the system to absorb shock while controlling rebound through the complementary properties of the two material types.
2Ease of manufacture
If single material pellets are used, then manufacturing is simple, but shock absorbing effectiveness is insufficient due to unrestrained rebound
Solution Approach 1:
The patent combines two different materials (rigid steel/iron pellets and soft rubber/plastic pellets) to create a composite pellet system. This composite approach maintains manufacturing simplicity while significantly improving shock absorbing effectiveness by using the complementary properties of hard and soft materials working together.
3Device complexity
If pellets are placed in a hollow shell structure head tube, then device complexity is reduced, but durability decreases due to insufficient protection against external striking force
Solution Approach 1:
The patent applies composite materials principle to the head tube structure by combining a hollow shell structure with internal rigid support elements (such as steel or iron inserts). This composite structural approach maintains the simplicity of the hollow shell while adding the durability needed to withstand external striking forces through the integrated rigid components.

Function Achieved in This Case
The solution effectively disperses and absorbs external striking forces, enhancing shock absorption, reducing the risk of hand injury, and increasing the hammer's durability by mixing rigid and soft pellets within the housings, thereby improving the overall stability and performance of the hammer.
Implementation Method 1
the rigid pellets are dispersed by the soft pellets to absorb impact, reducing rebound
