Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional laser-based systems use constant rotational laser scanning to achieve positioning, then they can provide three-dimensional layout capability, but the system complexity and cost increase significantly
Solution Approach 1:
The system divides the three-dimensional space into multiple two-dimensional laser planes that can be independently controlled. Each laser transmitter creates discrete laser planes at specific orientations rather than using a single continuously rotating beam, allowing the three-dimensional layout capability to be achieved through combination of simpler two-dimensional operations
Solution Approach 2:
The system dynamically adjusts the orientation and position of laser planes through electronic control of laser transmitters, eliminating the need for mechanical rotation. The laser planes can be repositioned and reoriented through software control, providing versatility without the mechanical complexity of rotating components
2Measurement precision
If conventional systems require constant rotational scanning to maintain positioning accuracy, then they achieve three-dimensional coverage, but the computational intensity and setup time increase
Solution Approach 1:
The system pre-establishes multiple laser planes at known orientations and positions before actual measurement begins. These pre-configured laser planes serve as reference frameworks that can be immediately used for positioning without requiring time-consuming rotational scanning or complex real-time computations during setup
3Adaptability or versatility
If laser transmitters emit multiple laser planes at different orientations, then three-dimensional positioning is achieved, but the requirement for highly controlled rotation speeds and unique modulation frequencies increases system complexity
Solution Approach 1:
The system replaces mechanical rotation control with electronic control of laser transmitters. Instead of requiring precise control of rotational speeds and modulation frequencies to distinguish between multiple laser planes, the system uses electronic addressing and control to identify and position each laser plane, eliminating the need for complex mechanical synchronization
Solution Approach 2:
Each laser transmitter is designed to emit multiple laser planes that can serve different functions - some for horizontal positioning, others for vertical positioning. The same physical device performs multiple positioning tasks without requiring separate specialized components, reducing overall system complexity
4Measurement precision
If conventional systems use rotating laser beams to scan retro-reflective targets, then positioning is achieved, but the method becomes overly complex and expensive
Solution Approach 1:
The system extracts and eliminates the rotating beam component from the positioning methodology. Instead of using a single rotating laser beam that scans through three-dimensional space, the system employs multiple stationary or independently controllable laser transmitters that emit discrete laser planes, removing the complex rotational scanning mechanism while maintaining positioning capability
Solution Approach 2:
The system uses multiple laser transmitters that can be independently controlled to create redundant laser plane configurations. These copies of the basic laser transmitter function allow the system to achieve three-dimensional positioning through combination of simpler two-dimensional laser plane measurements, avoiding the need for complex rotating mechanisms
