Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning method is used (raising false bottom, scaling, drawing lines), then the operation is simple and intuitive, but the operation is very cumbersome, requiring 3-4 people, with low efficiency and low accuracy
Solution Approach 1:
The patent replaces the manual mechanical positioning system (scaling, drawing lines by hand) with an automated optical-mechanical system. The laser transmitter mounted on the rotating platform automatically projects laser beams to indicate anchor chain positions on the false bottom, eliminating the need for manual scaling and drawing operations while significantly improving positioning efficiency and accuracy
Solution Approach 2:
The positioning device enables self-service operation where a single operator can control the rotating platform and laser transmitter to automatically position and mark multiple anchor chain locations. The system performs positioning calculations and laser projection autonomously based on input coordinates, reducing the need for multiple operators and improving overall productivity
2Ease of operation
If manual positioning method is used (raising false bottom, scaling, drawing lines), then the operation is simple and intuitive, but the positioning accuracy is low
Solution Approach 1:
The patent replaces imprecise manual measurement methods (scaling and drawing lines) with a precision optical system. The laser transmitter projects highly accurate laser beams that precisely indicate anchor chain positions on the false bottom, achieving positioning accuracy of several millimeters to centimeters, far superior to manual methods
Solution Approach 2:
The patent introduces a vertical dimension by mounting the laser transmitter on a rotating platform that can be positioned at different heights above the false bottom. This three-dimensional positioning capability allows the laser to project accurate position indicators from above, improving measurement precision compared to two-dimensional manual scaling on the false bottom surface
3Productivity
If automated laser positioning system is used, then positioning accuracy and efficiency are improved, but device complexity increases
Solution Approach 1:
The rotating platform serves multiple functions: it carries the laser transmitter, provides rotational movement for positioning, and can be adjusted to different heights. This multi-functionality reduces the need for separate components and simplifies the overall system structure while maintaining high positioning efficiency and accuracy
Solution Approach 2:
The system uses laser beams to create optical copies or projections of the anchor chain positions on the false bottom. Instead of physically measuring and marking each position manually, the laser projects visual indicators that replicate the precise locations, simplifying the operation while improving accuracy and efficiency
