Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users place objects based on guessed working range without visual guidance, then the device structure remains simple, but the ease of operation deteriorates and measurement accuracy decreases
Solution Approach 1:
The patent introduces an optical alignment indicator as an intermediary element between the measurement device and the object. This indicator is projected onto the object's surface to visually mark the measurement area boundaries and center position, serving as a mediator that guides users to correctly position objects within the working range without requiring complex mechanical guidance structures
Solution Approach 2:
The measurement area is pre-defined and visually marked on the object surface through projected optical indicators before the actual measurement takes place. The boundaries and center position are established in advance, allowing users to position objects correctly before initiating the measurement process, thereby improving ease of operation without adding mechanical complexity
2Measurement precision
If users repeatedly adjust the relative position of the device and object to achieve accurate measurement, then measurement precision can be improved, but the productivity deteriorates due to time-consuming adjustments
Solution Approach 1:
The patent implements a feedback mechanism by projecting optical alignment indicators that provide real-time visual information about whether the object is correctly positioned within the measurement area. Users can immediately see if the object aligns with the marked boundaries and center, eliminating the need for repeated trial-and-error adjustments and improving both measurement precision and productivity
3Measurement precision
If the working range of the lens is not visible to users, then the device structure remains simple, but the ease of operation deteriorates and measurement precision decreases
Solution Approach 1:
The patent uses optical projection to create visible color-coded or patterned indicators on the object surface that delineate the measurement area boundaries and center position. These visual markers transform the invisible optical working range into visible guidance cues, enabling precise object positioning without requiring complex mechanical measurement guides or structured light patterns
