Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric power tools rely heavily on user intuition to align the rotational axis of the tip tool with a predetermined directional axis, making precise orientation adjustments difficult.
Innovation Solution
An electric power tool design incorporating a holder, barrel, grip, level, and fixing member that allows the level to turn around the barrel in a plane perpendicular to the rotational axis, along with an auxiliary handle block for easier alignment and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a level is fixed rigidly on the tool body, then the structure is simple and stable, but the user cannot adjust the level's position to achieve proper alignment with the rotational axis
Solution Approach 1:
The level is made rotatable relative to the tool body through a rotation mechanism, allowing it to dynamically adjust its angular position. This enables the level to be oriented at different angles to match various rotational axes while maintaining a stable reading position once aligned.
Solution Approach 2:
The level assembly is divided into separate functional components: the level body, the rotation mechanism, and the mounting interface. This segmentation allows independent optimization of each component - the level body remains simple for accurate reading, while the rotation mechanism provides adjustment capability.
2Measurement precision
If the level is made adjustable to align with different rotational axes, then orientation precision is improved, but the device becomes more complex and harder to operate
Solution Approach 1:
The rotation mechanism enables the level to be dynamically positioned at any angle relative to the tool body, allowing precise alignment with the rotational axis through simple rotational movement rather than complex multi-axis adjustments.
Solution Approach 2:
The level incorporates visual indicators such as colored marks or illuminated elements that change orientation with the level's rotation, providing clear visual feedback to the user about the level's angular position relative to the tool body and facilitating precise alignment.
3Measurement precision
If the level is positioned close to the rotational axis for better alignment accuracy, then measurement precision is improved, but the level may interfere with the rotational movement of the tip tool
Solution Approach 1:
The level is positioned in a dimension (angular/rotational dimension) separate from the primary rotational path of the tip tool. By allowing the level to rotate independently around the tool body, it can be placed close to the rotational axis for accurate alignment measurement without physically blocking or interfering with the tip tool's rotation.
Solution Approach 2:
The level's rotational positioning mechanism allows it to be dynamically moved out of the way during tip tool rotation, eliminating interference while maintaining close proximity for accurate alignment measurement when needed.

AI summary
Disclosed herein are an electric power tool allowing the user to easily adjust its orientation in such a manner as to align the rotational axis of a tip tool with a predetermined directional axis, and a level and auxiliary handle block for use in such an electric power tool. The electric power tool (1) includes a holder (H1), a barrel (3), a grip (4), a level (5), and a fixing member (6). The holder (HI) fixes a tip tool (T1) thereon so as to allow the tip tool (T1) to rotate in a rotational direction (R1) around a rotational axis (A1). The holder (H1) is fixed to the barrel (3). The grip (4) protrudes from the barrel (3). The fixing member (6) is attached onto the barrel (3) and fixes the level (5) on the fixing member (6). The fixing member (6) is able to turn, along with the level (5), around the barrel (3), in a plane perpendicular to the rotational axis (A1) and in the rotational direction (R1) of the tip tool (T1), or in the opposite direction thereof.
