Surface Measuring Detector With Adjustable Tilt Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface property measuring devices face challenges in achieving both high adjustment resolution of measuring force within a small range and obtaining a large maximum measurement force, especially when dealing with deformable, small, or thin objects, as they either compromise on resolution or maximum force.
Innovation Solution
The detector incorporates a unique configuration with a rotatable arm, a transmission part, an elastic part, and a tilt adjusting part, allowing for fine adjustment of the measuring force by varying the inclination of the force when the transmission part and contact part interact, enabling both high resolution and large maximum force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the adjustment resolution of measuring force is made fine within the range of small measuring force, then the adjustment resolution becomes high, but the maximum value of measuring force becomes small and the adjustment range becomes narrow
Solution Approach 1:
The patent applies dynamics by making the inclination of the elastic part adjustable rather than fixed. The tilt adjusting part allows the user to change the inclination angle dynamically, which changes the relationship between the position of the other end of the elastic part and the measuring force. This enables the system to adapt between high resolution (smaller inclination angle) and large maximum force (larger inclination angle) based on measurement needs.
Solution Approach 2:
The patent changes the parameter of inclination angle of the elastic part to resolve the contradiction. By adjusting the inclination angle through the tilt adjusting part, the system modifies the conversion ratio between the displacement of the elastic part's end and the resulting measuring force. A smaller inclination angle provides finer adjustment resolution, while a larger inclination angle enables larger maximum measuring force.
2Force
If the adjustment range is extended to obtain the required maximum value of measuring force, then the maximum measuring force increases, but the adjustment resolution becomes rough and fine adjustment becomes difficult
Solution Approach 1:
The system dynamically adjusts the inclination angle of the elastic part to maintain high resolution across the entire adjustment range. When large measuring force is needed, the tilt adjusting part increases the inclination angle, which proportionally increases both the maximum force and the resolution, preventing the resolution from becoming rough.
Solution Approach 2:
The inclination angle parameter is changed to scale the entire measuring force range. By increasing the inclination angle, the system achieves larger maximum force while maintaining the same relative resolution, effectively resolving the contradiction between extended range and maintained precision.
