Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple skeleton recording devices are deployed to increase coverage area, then the surveillance area coverage is improved, but the power consumption and infrared interference increase
Solution Approach 1:
The patent implements periodic action by activating IR sensors in a round-robin manner across multiple skeleton recording devices. Each device takes turns being active while others remain inactive, reducing overall power consumption while maintaining continuous surveillance coverage. The system cycles through devices periodically, ensuring that at least one device is active at any given time to detect skeletal motion.
Solution Approach 2:
The surveillance area is segmented into multiple zones, each monitored by a specific skeleton recording device with a defined Field of View (FOV). Devices are positioned and configured with non-overlapping FOVs to cover different segments of the surveillance area, allowing comprehensive coverage while enabling selective activation of only the necessary devices for each segment.
2Area of stationary object
If multiple skeleton recording devices are deployed to increase coverage area, then the surveillance area coverage is improved, but the infrared interference increases
Solution Approach 1:
By implementing periodic activation where IR sensors are turned on and off in a round-robin fashion, the system ensures that only one device emits infrared radiation at a time. This eliminates infrared interference between simultaneous devices while maintaining continuous monitoring through sequential coverage of surveillance zones.
Solution Approach 2:
The harmful infrared emission function is extracted and isolated to a single active device at any given time, while other devices remain inactive. This separation prevents the harmful interaction of simultaneous infrared emissions while preserving the beneficial surveillance function through coordinated device activation.
3Measurement precision
If IR sensors are kept on continuously to ensure accurate detection, then the detection accuracy is improved, but the power consumption increases
Solution Approach 1:
The system employs periodic activation of IR sensors in a round-robin manner, where each device is activated for a specific duration and then deactivated. This ensures that detection accuracy is maintained during active periods while significantly reducing power consumption during inactive periods, achieving a balance between precision and energy efficiency.
Solution Approach 2:
While individual devices are activated periodically, the system maintains continuous useful action through coordinated switching between multiple devices. As one device deactivates, another activates to take over surveillance, ensuring that skeletal motion detection capability continues without interruption while reducing overall power consumption.

AI summary
A system and a method for monitoring motion skeleton recording devices (104) is described. The method includes detecting, by a processor (110) of a monitoring system (102), at least one human skeleton in a field of view (FOV) of the first skeleton recording device (104). Based on the detection, a message is transmitted to rest of the plurality of skeleton recording devices (104) to switch ON and OFF corresponding infrared (IR) sensors in a round robin manner. The method further includes identifying one or more second skeleton recording device (104) based on a direction of traversal of the at least one human skeleton from the FOV of the first skeleton recording device (104) to a FOV of the one or more second skeleton recording devices (104). Based on the identification, the one or more second skeleton recording devices (104) are notified to activate the corresponding IR sensor.
