Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smartphone is used to operate IoT devices via network, then operation functionality is achieved, but convenience deteriorates due to frequent manual holding and operation
Solution Approach 1:
The system enables automatic operation of IoT devices through contactless recognition. When a user approaches an IoT device, the imaging unit captures images, the control unit identifies the device and executes corresponding operations automatically, eliminating the need for manual smartphone operation and reducing time loss.
Solution Approach 2:
The patent replaces manual mechanical operation (holding and tapping smartphone) with an automated optical recognition system. The imaging unit captures visual information, and the control unit processes this data to automatically control IoT devices, substituting manual mechanical actions with automated optical-mechanical systems.
2Ease of operation
If physical input switches are added to enable direct control, then ease of operation improves, but device complexity and installation cost increase
Solution Approach 1:
The patent replaces physical mechanical switches with an optical recognition system. Instead of requiring physical buttons or switches on devices, the imaging unit captures images of objects, and the control unit automatically identifies and executes corresponding operations, eliminating the need for complex physical input mechanisms.
Solution Approach 2:
The imaging unit serves as an intermediary between the user and the IoT device. Rather than direct physical contact through switches, the user simply approaches the device, and the imaging unit mediates the interaction by capturing visual information to trigger automated control operations.
3Measurement precision
If a fixed-focus lens is used in the imaging unit, then device simplicity is maintained, but image quality deteriorates when objects are at varying distances
Solution Approach 1:
The patent employs a movable lens structure that can dynamically adjust its position relative to the imaging element. The lens can move along the optical axis to change the focal distance, allowing the system to adapt to objects at varying distances while maintaining sharp focus without requiring complex automated focus mechanisms.
Solution Approach 2:
The patent changes the physical parameter of lens position to adjust focus. By moving the lens along the optical axis to different distances from the imaging element, the system can focus on objects at different depths, improving image quality without requiring complex computational focus adjustment or multiple fixed-focus lenses.
