Hand-Held Power Tool User Interface Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held power tools face complexities in assembly due to intricate connections between internal components and the machine housing, leading to potential faulty or incorrect connections.
Innovation Solution
A hand-held power tool design where the user interface unit is arranged on an inner element, allowing for simplified assembly by being inserted or connected as a single piece into the machine housing, eliminating the need for intricate fine work and reducing the risk of incorrect connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If internal components are connected separately to the machine housing, then flexibility in component placement is improved, but assembly complexity and risk of incorrect connections increase
Solution Approach 1:
The user interface unit is merged with the inner element to form a single integrated assembly. This combining of components that were previously separate (user interface unit and inner element) reduces the number of individual connections required during assembly, thereby reducing assembly complexity while maintaining the ability to position the integrated unit as a whole within the machine housing
2Adaptability or versatility
If multiple separate connections are made during assembly, then component positioning flexibility is improved, but the risk of faulty connections increases
Solution Approach 1:
By combining the user interface unit with the inner element into a single integrated assembly, the number of separate connections required during assembly is reduced. This integration ensures that connections are made at fewer, more controlled points, thereby reducing the risk of faulty or incorrect connections while maintaining proper component positioning
3Manufacturing precision
If intricate fine work is performed during assembly, then precise component alignment is improved, but assembly time and complexity increase
Solution Approach 1:
The user interface unit is pre-assembled with the inner element before installation into the machine housing. This preliminary assembly action ensures that precise alignment and connections are established in advance under controlled conditions, eliminating the need for intricate fine work during final assembly into the housing

AI summary
A hand-held power tool, in particular an angle grinder, includes a drive unit, a machine housing, and a user interface unit. The machine housing surrounds the drive unit. The drive unit is configured to transmit a motion to an output unit. The user interface unit is configured to operate the hand-held power tool, and is either (i) positioned on an inner element of the hand-held power tool, in particular a flat outer surface of the inner element, or (ii) connected to the inner element, in particular the flat outer surface of the inner element.
