Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a two-piece magnetic sensor design is used, then the sensor can detect door/window opening, but the design is aesthetically unpleasing and bulky
Solution Approach 1:
The patent combines the magnet and sensor into a single integrated unit that attaches to the door edge, eliminating the need for separate magnetic components. This single-piece design maintains the security sensing function while achieving a sleek, aesthetically pleasing appearance that contrasts with the traditional two-piece bulky design.
2Measurement precision
If the gap between magnet and sensor is made small for sensitivity, then detection capability improves, but false triggers increase
Solution Approach 1:
The patent replaces the traditional magnetic field-based detection with an optical sensor system that uses light emission and detection. The optical sensor detects door/window opening through optical changes rather than magnetic field changes, eliminating the false trigger problem associated with magnetic sensors while maintaining high detection sensitivity through the optical detection mechanism.
3Strength
If molding on doors/windows is present, then structural integrity is maintained, but proper positioning of magnets becomes difficult
Solution Approach 1:
The patent replaces the magnetic attachment system with an optical sensor system that can be positioned and secured independently of door moldings. The optical sensor unit can be attached to the door edge or window frame in various locations, allowing flexible positioning that overcomes the constraints imposed by door moldings while maintaining structural integrity.
4Extent of automation
If existing wireless security sensors are used, then connectivity is achieved, but power supply issues arise
Solution Approach 1:
The patent replaces traditional battery-powered wireless sensors with an optical sensing system that can be hardwired into the building's existing electrical infrastructure. This eliminates the need for separate power supplies for each sensor unit, resolving power supply issues while maintaining wireless communication capabilities through the optical detection mechanism.
