Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools with pivoting mechanisms suffer damage from external shocks when attempting to loosen them from work pieces, leading to connection failures.
Innovation Solution
A buffer structure comprising a tool head, first and second shaft structures, and a resilient member that allows the tool head to move relative to the shaft structures, absorbing shocks and preventing damage to connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tool is hit with external force to loosen it from the work piece, then the tool can be removed from the work piece, but the pivoting mechanism suffers damage
Solution Approach 1:
The patent applies beforehand cushioning by introducing a buffer structure between the tool head and the shaft structures. This buffer structure includes a resilient member that is pre-positioned to absorb impact forces before they reach the pivoting mechanism. When the tool is hit with external force, the resilient member compresses and dissipates the shock energy, preventing damage to the pivoting mechanism while still allowing the tool to be loosened from the work piece.
Solution Approach 2:
The patent uses an intermediary approach by introducing a buffer structure as a mediator between the external impact force and the pivoting mechanism. The buffer structure includes a resilient member that acts as an intermediary element, transferring and absorbing the impact energy rather than allowing it to directly transmit to the pivoting mechanism. This intermediary structure protects the sensitive pivoting components while still enabling the tool to respond to the external force for loosening.
2Stability of the object's composition
If the tool head is fixed rigidly to the shaft structures, then structural stability is improved, but shock damage to connections occurs
Solution Approach 1:
The patent applies dynamics by transitioning from a rigid fixed connection to a movable connection with controlled degrees of freedom. The tool head is movably coupled to the shaft structures through the buffer structure, allowing relative movement between components. This dynamic coupling enables the structure to absorb shocks through controlled motion while maintaining overall structural stability during normal operation. The resilient member provides both movement capability and stabilizing force.
Solution Approach 2:
The patent uses parameter changes by modifying the connection characteristics between the tool head and shaft structures. Instead of a purely rigid connection, the buffer structure introduces elasticity and controlled mobility. The resilient member changes the mechanical parameters of the connection, providing both stability during normal use and shock absorption during impact events. This parameter change allows the system to adapt its rigidity based on operating conditions.

Function Achieved in This Case
The buffer structure effectively absorbs shocks, protecting the tool's connections and preventing damage during use on work pieces by allowing the tool head to move relative to the shaft structures, thereby enhancing durability and reliability.

AI summary
A tool including a buffer structure adapted to prevent shocks includes a tool head, a first shaft structure, and a second shaft structure. The tool head has a first connecting portion. The second shaft structure is attached to the slide and links with the tool head. The second shaft structure is movable with respect to the first shaft structure such that the tool head is moved toward and away from the first shaft structure. The second shaft structure has a second connecting portion receiving the pivot. The tool head is pivotal with respect to the second shaft structure. Further, a resilient member is disposed between the first and the second shaft structures. The second shaft structure is biased by the resilient member.
