Power Tool Cover With Remote Operation Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In power tools with a movable cover portion, users must bring their hand close to the tip tool when moving the cover, posing safety risks, especially when the tool is in operation.
Innovation Solution
Incorporating an operation member mechanically connected to the movable cover portion allows users to move the cover without direct hand contact, enabling safe operation even when the tool is in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable cover portion is designed to be directly movable by user hand, then the ease of operation is improved, but the user safety deteriorates due to the risk of hand injury from the rotating tip tool
Solution Approach 1:
An operation member is introduced as an intermediary between the user's hand and the movable cover portion. The operation member is mechanically connected to the movable cover portion and transmits the user's operational force to move the cover without requiring direct hand contact with the cover near the rotating tip tool, thus resolving the contradiction between ease of operation and user safety
2Object-affected harmful factors
If the operation member is added to move the movable cover portion, then the user safety is improved, but the device complexity increases
Solution Approach 1:
The operation member is designed to be mechanically connected to the movable cover portion in such a way that it leverages the existing structure and movement of the cover mechanism. The operation member utilizes the natural movement path and mechanical linkage already present in the cover system, adding minimal complexity while achieving the safety objective of remote operation

AI summary
A power tool may include: a motor; a power transmission mechanism connected to the motor; a housing that houses the motor and the power transmission mechanism; a tip tool holder connected to the power transmission mechanism and holding a tip tool; and a cover covering at least a part of the tip tool. The cover may include: a fixed cover portion fixed to the housing; a movable cover portion movable with respect to the fixed cover portion; and an operation member mechanically connected to the movable cover portion and configured to move the movable cover portion with respect to the fixed cover portion.
