Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple positioning interfaces and sensors are used to determine position and orientation, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The positioning system is divided into multiple independent positioning interfaces (e.g., front, rear, left, right interfaces) distributed on the frame, each capable of providing positioning information. This segmentation allows the system to achieve high positioning accuracy through multiple data points while keeping each individual interface relatively simple in design.
Solution Approach 2:
The positioning interfaces and sensors are designed to serve multiple functions: determining both position and orientation of the hair cutting device, providing redundancy for error compensation, and enabling operation under various conditions (including obstructions). This multi-functionality justifies the increased device complexity by delivering comprehensive positioning capabilities.
2Reliability
If positioning ranges are dynamically adjusted based on signal strength and subtended angle, then positioning reliability is improved, but computational requirements increase
Solution Approach 1:
The positioning system dynamically adjusts which positioning interfaces are active based on real-time conditions such as signal strength and subtended angle. This dynamic adaptation improves positioning reliability by selecting the most reliable interfaces under varying conditions, while the computational complexity is managed through algorithmic optimization.
Solution Approach 2:
The system continuously monitors signal strength and subtended angle from positioning interfaces and uses this feedback to adjust positioning range selections. This feedback mechanism ensures high positioning reliability by adapting to changing conditions, with computational requirements balanced through efficient feedback processing algorithms.
3Measurement precision
If computational methods are used to compensate for inaccuracies and obstructions, then positioning precision is improved, but processing time increases
Solution Approach 1:
The system pre-establishes relationships between positioning interfaces and calculates expected positioning ranges before actual hair cutting operation begins. This preliminary computation allows real-time positioning to be performed quickly with minimal processing delay, while still achieving high precision through pre-computed compensation algorithms.
Solution Approach 2:
The system changes computational parameters dynamically based on operating conditions, selecting appropriate compensation methods and algorithms based on signal quality, obstruction levels, and positioning requirements. This parameter adaptation maintains high positioning precision while optimizing processing time by using simpler computations when conditions permit.
