Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth pairing method is used for device binding, then devices can be connected wirelessly, but the binding process becomes complex and time-consuming
Solution Approach 1:
The patent introduces a directional signal (infrared, ultrasonic, or UWB) as an intermediary carrier to transmit binding request messages. This intermediary enables direct targeted communication between controlling device and controlled device, eliminating the need for device scanning and selection in traditional Bluetooth pairing, thus simplifying the binding process and reducing time
Solution Approach 2:
The patent replaces the mechanical interaction of manual device selection and pairing confirmation with automated directional signal transmission. The controlling device automatically sends binding requests through directional signals, and the controlled device automatically responds, substituting the manual mechanical pairing process with an automated signal-based system
2Productivity
If traditional Bluetooth scanning is used to find controlled devices, then all available devices can be discovered, but the process becomes complex requiring user selection
Solution Approach 1:
The patent applies local quality by using directional signals that transmit binding requests to specific spatial locations or specific controlled devices. Instead of broadcasting to all devices equally, the signal is directed locally to the intended target, eliminating the need for users to scan and select from multiple devices, thus improving efficiency and reducing process complexity
Solution Approach 2:
The patent extracts the device selection step from the binding process. By using directional signals that inherently target specific controlled devices, the method removes the need for users to manually select devices from a list, extracting this complex step out of the overall binding process and significantly simplifying user interaction
