Auxiliary Grip Shock Absorber Layout for Compact Impact Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary grips for hammer drills require larger shock absorbers due to the use of compression springs in series, which increases the overall size and may not efficiently absorb impacts during operation.
Innovation Solution
An auxiliary grip design featuring a base with elastic members that urge a grip body in two directions along the striking axis, incorporating a shock absorber with reduced size by using compression coil springs and a cushioning member to absorb impacts effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression springs are arranged in series to absorb impact, then impact absorption capability is improved, but the size of the shock absorber increases
Solution Approach 1:
The patent transitions from a single-direction series spring arrangement to a multi-directional configuration where elastic members are arranged both in series and in parallel, utilizing spatial dimensions to achieve compact shock absorption. The elastic members extend in multiple directions from the grip base, absorbing impact forces from various angles simultaneously.
Solution Approach 2:
The patent combines multiple elastic members in a integrated shock absorber structure where series and parallel arrangements coexist. This merging of configuration approaches allows the system to achieve both the impact absorption of series springs and the compactness of parallel springs within a single unified structure.
2Reliability
If a larger shock absorber is used to accommodate series compression springs, then impact absorption is improved, but the auxiliary grip becomes bulkier and less ergonomic
Solution Approach 1:
The elastic members are arranged to extend in multiple directions from the grip base rather than linearly, utilizing three-dimensional space efficiently. This radial or multi-directional arrangement allows compact shock absorption without increasing the linear dimensions of the grip, maintaining ergonomic proportions.
Solution Approach 2:
The shock absorber structure concentrates elastic members in specific directional zones around the grip base, providing targeted impact absorption where needed while leaving other areas compact. This localized arrangement maintains overall grip compactness while delivering effective shock absorption in critical directions.
