Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light-beam emitter is integrated with a display panel to enable remote operation, then interaction capability is improved, but the complexity of realizing convenient interaction between the two components increases
Solution Approach 1:
The patent combines the light-beam emitter and display panel into an integrated system where the emitter is positioned directly on or near the display panel. The control assembly merges projection control and operation control functions into a single device, enabling both positioning and interaction operations without requiring separate external devices. This integration simplifies the overall system while maintaining versatile interaction capabilities.
Solution Approach 2:
The light-beam emitter is designed with multi-functionality to perform both projection operations and interaction operations through a single device. The control assembly can switch between projection mode (emitting projection beams for positioning) and operation mode (emitting operation beams for interaction), allowing one device to serve multiple purposes and reducing system complexity.
2Measurement precision
If distinct projection beams and operation beams are emitted to enable precise interaction, then operation precision is improved, but the device complexity increases
Solution Approach 1:
The patent segments the beam emission functions into distinct projection beams and operation beams with different characteristics. The control assembly manages these segmented beam types separately, allowing precise control of each beam's properties (such as wavelength, intensity, or modulation patterns) to achieve different operational goals without interfering with each other.
Solution Approach 2:
The system dynamically switches between emitting projection beams and operation beams based on the operational mode required. The control assembly adjusts the beam emission characteristics in real-time, transitioning between different beam types as needed for positioning or interaction operations, enabling precise control without requiring multiple fixed emission paths.
