Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional water level and pin methods are used to maintain grid horizontality, then measurement accuracy can be achieved, but the operation becomes labor-intensive and inefficient
Solution Approach 1:
The patent replaces the traditional mechanical water level and pin system with an electronic sensor-based system. The sensor part detects the vertical position electronically, and the laser light source projects reference lines optically, eliminating the need for manual water level checks and physical pin placements while maintaining measurement accuracy.
Solution Approach 2:
The device performs self-leveling through the sensor part that automatically detects and indicates vertical position. The system serves itself by providing automatic feedback through the laser display, eliminating the need for continuous manual intervention and repeated checks required by traditional methods.
2Manufacturing precision
If repeated checks with water levels and pins are performed to ensure grid horizontality, then positioning accuracy is maintained, but time consumption increases
Solution Approach 1:
The sensor part performs preliminary detection of the vertical position before grid installation begins. The laser light source pre-establishes the reference lines and horizontality markers, allowing workers to immediately begin accurate grid placement without performing repeated checks during the installation process.
Solution Approach 2:
The sensor part provides continuous feedback on vertical positioning through the laser display system. This real-time feedback mechanism allows workers to maintain positioning accuracy throughout the grid installation process without needing to stop and perform repeated manual checks with water levels and pins.
3Device complexity
If manual methods are used to maintain grid horizontality, then equipment complexity remains low, but operation difficulty increases
Solution Approach 1:
The laser light source acts as an intermediary between the sensor part and the grid installation process. It translates the sensor's vertical position detection into visible laser reference lines that guide grid placement, making the operation easier without significantly increasing equipment complexity.
Solution Approach 2:
The laser light source provides visual information through light projection, creating visible reference lines and markers. This optical indication system replaces the need for workers to interpret physical water levels and pin positions, significantly easing the operation while adding only minimal complexity to the equipment.
