Problem
Handheld machine tools face challenges in achieving efficient assembly, maintenance, and cost-effective connections between gear housings due to limited constructive space and the need for secure, detachable connections that absorb operational forces.
Innovation Solution
A handheld tool device design featuring a bracket holder unit with elastic holding elements that connect gear housings via radial or axial openings, providing a secure, detachable, and space-efficient connection that absorbs operational forces, allowing for efficient assembly and reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional screw connections or locking connections are used to connect gear housings, then secure connection is achieved, but device complexity and assembly time increase
Solution Approach 1:
The connection system is segmented into a bracket holder unit with multiple independent holding elements (brackets) that can be individually positioned and engaged. Each holding element acts as an independent connection point, allowing distributed securing without requiring complex integrated fastening mechanisms.
Solution Approach 2:
The holding elements are designed to automatically engage with the gear housings through elastic deformation and counter-force generation. The elastic material self-adjusts to secure the connection without requiring additional locking mechanisms or complex assembly procedures.
2Strength
If rigid fastening arrangements are used to connect gear housings, then connection strength is improved, but constructive space efficiency and weight efficiency deteriorate
Solution Approach 1:
The holding elements are made of elastic material that can deform and flex to accommodate the gear housings. This flexible connection provides sufficient strength through elastic counter-force while occupying minimal space, eliminating the need for bulky rigid fastening structures.
Solution Approach 2:
The elastic properties of the holding elements allow the connection to adapt to varying operational conditions. The material's elasticity enables the connection to maintain strength while adjusting to space constraints, providing a space-efficient solution that rigid connections cannot achieve.
3Reliability
If multiple separate fastening components are used to secure gear housings, then connection reliability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
Multiple holding elements are integrated into a single bracket holder unit that can be manufactured as one piece or pre-assembled module. This merging of components reduces the total number of separate parts, simplifies manufacturing, and lowers assembly complexity while maintaining reliable multi-point connection.
Solution Approach 2:
The bracket holder unit serves multiple functions simultaneously: it provides structural support, secures the gear housings at multiple points, and allows for easy assembly and disassembly. This multi-functionality eliminates the need for separate components for each function, reducing overall complexity and manufacturing cost.
4Ease of repair
If detachable connections are implemented for easy maintenance, then ease of repair is improved, but connection stability during operation may deteriorate
Solution Approach 1:
The connection system transitions from static rigid fastening to dynamic elastic engagement. The holding elements can be easily engaged and disengaged by overcoming the elastic counter-force, enabling simple detachable connection while maintaining stable operational connection through the elastic securing mechanism.
