360-Degree Mounting Element for Jigsaw Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held power tool devices, such as jigsaws, face challenges in efficiently adjusting and stabilizing components during operation, leading to increased component costs, assembly complexity, and user difficulty in achieving precise orientations and positions.
Innovation Solution
The implementation of a mounting element extending 360° around an adjustment axis, combined with a spring element for stabilization, detent elements for precise positioning, beveled regions for increased clamping force, and an air control element for improved airflow, allows for tool-free adjustments and enhanced user control over the tool's orientation and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components are used for mounting and adjustment, then stability and precision are improved, but device complexity and assembly effort increase
Solution Approach 1:
The mounting element is designed as a one-piece component that extends 360° around the adjustment axis, integrating multiple functions (mounting, adjustment, stabilization) into a single structure. This eliminates the need for separate mounting brackets, adjustment mechanisms, and stabilization components, thereby reducing assembly complexity while maintaining reliability through the integrated design
2Device complexity
If a one-piece mounting element extending 360° is used, then device complexity and assembly effort are reduced, but manufacturing precision requirements increase
Solution Approach 1:
The one-piece mounting element is designed to perform multiple functions simultaneously: providing structural support, enabling 360° adjustment around the adjustment axis, and ensuring stable mounting. This multi-functionality compensates for the reduced manufacturing precision requirements by relying on the overall geometric design rather than tight tolerances of multiple assembled parts
3Ease of operation
If spring element is used to load mounting element during adjustment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The spring element is integrated into the mounting element structure, allowing the adjustment mechanism to be self-actuating. The spring provides continuous loading force that enables the base element to be easily adjusted without requiring additional actuators or complex control systems, while the spring itself is a simple component that does not significantly increase overall device complexity

Function Achieved in This Case
This configuration reduces component costs and assembly effort, simplifies adjustments, and enhances user control over the tool's orientation and position, improving operational efficiency and flexibility.
Implementation Method 1
The adjusting device has a spring element that is provided to load the mounting element at least during an adjustment. Preferably, the spring element stabilizes the base element in so doing.
