Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed set of user inputs (six degrees of freedom) is used to control the robotic manipulator, then the interface structure remains simple, but the ability to communicate natural and consistent motion is limited
Solution Approach 1:
The patent introduces an intermediary system consisting of wearable sensors and a database that translates human motion into robotic control commands. The wearable device captures full-body motion data, the database stores and processes this data to extract motion patterns, and the system uses this information to control the robotic manipulator beyond the limitations of traditional six-degree-of-freedom interfaces.
Solution Approach 2:
The patent replaces the mechanical joystick interface with a sensor-based wearable system. Instead of using physical mechanical controls limited to six degrees of freedom, the system uses wearable sensors to capture natural human motion, processes this data through a database, and translates it into robotic control commands, enabling more intuitive and natural motion communication.
2Ease of operation
If a complex structural design is used to receive user inputs for continuous transition, then natural and consistent motion can be achieved, but the cost of the interface increases
Solution Approach 1:
The patent uses wearable sensors to copy and capture the operator's natural motion patterns. The system records and stores these motion patterns in a database, creating a digital representation of human movement that can be replayed and processed to control the robotic manipulator, eliminating the need for expensive complex mechanical interfaces.
Solution Approach 2:
The patent changes the parameters of the control system from fixed six-degree-of-freedom mechanical inputs to multi-parameter sensor data capturing full-body motion. By using wearable sensors that measure various physiological and motion parameters, the system achieves continuous and natural motion control without requiring complex mechanical structures.
3Measurement precision
If traditional interfaces are used to control anthropomorphic effectors, then the interface cost remains low, but the control accuracy and natural motion representation are insufficient
Solution Approach 1:
The patent segments the control system into multiple independent components: wearable sensors for data collection, a database for storage and processing, and a control system for executing commands. This segmentation allows each component to be optimized independently, achieving high measurement precision through specialized sensors and sophisticated data processing without requiring an overly complex integrated interface.
