Power Tool Battery Vibration Suppression via Filter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tools driven by detachable batteries face issues with vibration-induced wear on connecting terminals and the need for separate replacement of vibration-absorbing members and filters, leading to cumbersome maintenance.
Innovation Solution
A power tool design where a filter component with elastic absorbing parts is integrated into the battery loading part, allowing for simultaneous replacement of the filter and vibration-suppressing mechanism, thereby simplifying maintenance and reducing operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elastic absorbing member is attached into a slide rail part for loading a battery to suppress vibration, then battery vibration is reduced, but the elastic absorbing member needs regular replacement which is troublesome and may be left unreplaced
Solution Approach 1:
The patent combines the filter component and the elastic absorbing member into a single integrated assembly. The filter securing part that holds the filter also functions as the elastic absorbing member that suppresses battery vibration. This merging allows both components to be replaced simultaneously in a single operation, eliminating the troublesome separate replacement of the elastic absorbing member while maintaining its vibration suppression function.
2Object-affected harmful factors
If a filter is fitted in the air inlet opening to prevent dust entry, then dust protection is improved, but the filter needs regular replacement which is troublesome
Solution Approach 1:
The patent integrates the filter component with the elastic absorbing member assembly. The filter is secured by the filter securing part which is part of the same detachable assembly as the elastic absorbing member. This allows the filter to be replaced simultaneously with the elastic absorbing member in a single operation, making maintenance less troublesome while maintaining dust protection.
3Reliability
If the filter securing part is exposed into the battery loading part to suppress battery play, then battery stability is improved, but the filter component structure becomes more complex
Solution Approach 1:
The filter securing part serves multiple functions: it secures the filter in place and simultaneously acts as the elastic absorbing member that suppresses battery vibration and play. By making the filter securing part multi-functional, the patent achieves battery stability without adding separate components, thus avoiding increased structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This integrated solution effectively suppresses battery vibration and play, facilitating easier and more efficient replacement, reducing maintenance time and effort while maintaining the tool's functionality.
Implementation Method 1
an elastic absorbing member is attached into a slide rail part for loading a battery so that the battery is elastically supported by the elastic absorbing member, thereby absorbing vibration
Implementation Method 2
a filter is disposed to prevent dust from entering the housing

AI summary
A power tool is configured to permit a part for suppressing play of a battery and a filter to be replaced together in a single operation. The power tool (belt-type grinding tool) is driven by a detachably loaded battery. The power tool includes a housing having a battery loading part and an air inlet opening, and a filter component detachably attached to the housing. The filter component has a filter covering the air inlet opening and a filter securing part holding the filter and secured to the housing. The filter securing part has a frame portion surrounding the perimeter of the filter, and three mounting leg portions extending from the frame portion. The first and second mounting leg portions partially project into the battery loading part. The first and second mounting leg portions abut against the battery to suppress play of the battery with respect to the housing.
