Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a web-based application is used to control robotic devices through mobile devices, then compatibility across different devices and operating systems is improved, but the complexity of normalizing motion data from varying sensor types is increased
Solution Approach 1:
The patent introduces a web-based application as an intermediary layer between mobile device motion sensors and robotic device control systems. This intermediary normalizes motion data from various sensor types (accelerometers, gyroscopes, magnetometers) across different mobile devices and translates it into standardized commands that the robotic device can execute, thereby achieving cross-platform compatibility without requiring device-specific applications.
Solution Approach 2:
The web-based application transforms motion data by changing its parameters - converting raw sensor readings into normalized motion parameters. This parameter transformation allows data from different sensor types and operating systems to be standardized into a common format that can control the robotic device uniformly, resolving the compatibility issue through parameter standardization.
2Ease of operation
If motion sensors on mobile devices are used for teleoperation, then mobility and flexibility are improved, but compatibility issues arise due to varying sensor types and operating systems
Solution Approach 1:
The web-based application provides universal functionality by supporting multiple mobile device types and operating systems through a single platform. It handles various sensor types (accelerometers, gyroscopes, magnetometers) and translates them all into standardized control commands, making the teleoperation system universally compatible across different mobile devices without requiring device-specific applications.
3Reliability
If traditional robotic control systems are used, then reliability is maintained, but mobility and flexibility are reduced due to stationary or laptop-based operation requirements
Solution Approach 1:
The patent replaces the traditional mechanical control interface (stationary control panels or laptop connections) with a wireless mobile-based control system. Mobile devices with motion sensors substitute for traditional control mechanisms, enabling operators to control robotic devices remotely with full mobility while maintaining control reliability through standardized command protocols.
