Power Tool Handle Socket Mounting for Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld power tools with electric connecting sockets face challenges in cost-effectiveness and reliability, particularly in terms of vibration damping and mounting efficiency.
Innovation Solution
The handle components of the handheld power tool, specifically the handle shells and cover, are designed to serve as a dual-purpose mounting for the electric connecting socket, allowing for relative movement and vibration damping through the use of thermoplastic elastomer materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate mounting structure is used for the electric connecting socket, then the mounting is secure and reliable, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the mounting function with the handle component itself. The handle (component 2) is designed to directly receive and secure the electric connecting socket (component 1) without requiring a separate mounting structure. This integration reduces the number of parts while maintaining secure attachment of the socket to the power tool.
Solution Approach 2:
The handle serves multiple functions: it provides grip for the user, structural support for the power tool, and simultaneously acts as a mounting structure for the electric connecting socket. This multi-functionality eliminates the need for dedicated mounting components, simplifying the overall device.
2Stability of the object's composition
If rigid mounting is used for the electric connecting socket, then the mounting is stable, but vibration damping is insufficient
Solution Approach 1:
The patent changes the material parameter of the handle from rigid to elastomeric. The handle is made of an elastomer material that provides both mechanical stability for mounting the socket and inherent vibration damping properties. This material parameter change allows the same component to achieve both stable mounting and vibration reduction.
Solution Approach 2:
The handle utilizes elastomeric material that combines the properties of flexibility and structural integrity. This composite material approach allows the handle to simultaneously provide stable mounting for the electric connecting socket and effectively dampen vibrations transmitted to the socket during operation.
3Reliability
If multiple separate components are used for mounting, then the mounting is secure, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent merges the mounting function into the handle component itself, eliminating the need for separate mounting brackets, screws, or attachment mechanisms. The handle is designed with an integrated socket reception structure that secures the electric connecting socket directly, reducing part count and manufacturing complexity.
Solution Approach 2:
The handle serves as both the user-grip component and the mounting structure for the electric connecting socket. This multi-functional design eliminates the need for dedicated mounting components, simplifying manufacturing processes and reducing assembly steps while maintaining secure socket attachment.
