Indirect Positioning Apparatus for Optical Tissue Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical detection methods face challenges in ensuring measurement conditions during the positioning process, leading to inaccurate detection due to direct contact with the measurement region and lack of positioning features, which affects the accuracy of tissue element measurements.
Innovation Solution
A positioning method and apparatus that determine a positioning portion based on the tissue structure relative position and feature conditions of the object, ensuring a predetermined measurement posture by using a supporting part and positioning part to indirectly position the measurement region, minimizing skin status changes and maintaining a predetermined distance range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the positioning apparatus directly contacts the measurement region to position it, then the positioning accuracy is improved, but the measurement condition cannot be ensured and the detection accuracy deteriorates
Solution Approach 1:
The patent introduces a positioning portion as an intermediary between the positioning apparatus and the measurement region. The positioning apparatus contacts the positioning portion (not the measurement region directly), and the positioning portion transmits the positioning action to the measurement region. This mediator prevents direct contact between the positioning apparatus and measurement region, ensuring measurement conditions are maintained while still achieving accurate positioning.
2Ease of operation
If the positioning apparatus directly contacts the measurement region, then the positioning can be performed, but the skin status changes and the detection accuracy deteriorates
Solution Approach 1:
The positioning portion serves as a mediator that receives the positioning action from the positioning apparatus and transmits it to the measurement region. This indirect positioning method allows the positioning operation to be performed easily while preventing the positioning apparatus from directly affecting the skin status of the measurement region, thus eliminating the harmful effect of skin status changes.
3Device complexity
If the measurement region is positioned directly, then the positioning process is simple, but the measurement posture cannot be ensured and the detection accuracy deteriorates
Solution Approach 1:
The positioning portion is introduced as an intermediary element that enables the positioning apparatus to control the measurement posture indirectly. While this adds a component to the system, it ensures that the measurement posture meets predetermined conditions, thereby improving detection accuracy. The complexity increase is minimal and justified by the significant improvement in measurement precision.
