Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a device performs sensing measurements using its own sensing capabilities, then the device can obtain sensing data, but devices with limited sensing capabilities or resources cannot perform accurate sensing measurements
Solution Approach 1:
The patent introduces a sensing-by-proxy mechanism where an initiator device requests a responder device to perform sensing measurements on its behalf. The responder acts as an intermediary that executes the sensing tasks using its own capabilities and returns the measurement results to the initiator. This resolves the contradiction by enabling devices with limited sensing capabilities to access accurate sensing data through devices with superior capabilities.
Solution Approach 2:
The initiator device obtains sensing measurement results generated by the responder device, effectively copying the sensing capabilities of the responder. Instead of requiring the initiator to possess native sensing hardware, the system allows it to utilize and copy the sensing results produced by another device, thereby expanding applicability without compromising measurement accuracy.
2Measurement precision
If a device with greater sensing capabilities performs measurements, then measurement accuracy improves, but resource demands on the initiator device increase
Solution Approach 1:
The responder device serves as an intermediary that performs the computationally intensive sensing measurements using its own resources. The initiator device only needs to send a simple request and receive results, avoiding the energy cost of running complex sensing algorithms locally. This distributes resource consumption to the device best suited for it.
Solution Approach 2:
The responder device performs sensing measurements for its own benefit and for initiators simultaneously. By maintaining its own sensing capabilities, the responder can serve multiple initiators without additional resource overhead, as the sensing infrastructure already exists and is being utilized efficiently.
3Ease of operation
If devices perform sensing measurements independently, then each device maintains autonomy, but devices with limited capabilities cannot perform measurements
Solution Approach 1:
The system establishes a clear intermediary relationship where the responder device mediates the sensing measurement process. The initiator simply sends a request frame and receives a response frame with results, maintaining operational simplicity. The responder reliably executes the sensing tasks using its dedicated capabilities, ensuring sensing functionality is always available regardless of initiator constraints.
