Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless communication techniques are used to communicate wirelessly, then wireless communication can be established, but interference between devices increases and power consumption increases
Solution Approach 1:
The patent changes the power level parameter by introducing a low power mode that operates at a lower power level than traditional wireless communication techniques. This allows devices to communicate wirelessly with reduced interference, as the lower power level generates less electromagnetic noise in the shared spectrum.
Solution Approach 2:
The patent employs spread spectrum techniques where the signal is spread across a wider frequency band rather than concentrated in a narrow band. This copying of the signal across multiple frequencies allows for better interference resistance and enables multiple devices to share the spectrum more effectively.
2Reliability
If traditional wireless communication techniques are used to overcome interference, then communication reliability improves, but power consumption increases
Solution Approach 1:
The patent fundamentally changes the power consumption parameter by operating at a lower power level. This low power mode maintains communication reliability through spread spectrum techniques while consuming significantly less energy than traditional high power wireless communication methods.
Solution Approach 2:
The patent implements periodic transmission patterns where devices transmit wirelessly only when necessary rather than continuously. This periodic operation reduces overall power consumption while maintaining communication reliability when data needs to be transmitted.
3Length of moving object
If power amplifier is used to increase transmission range, then communication range improves, but power consumption increases
Solution Approach 1:
The patent changes the power parameter by eliminating the need for a power amplifier in the traditional sense. Instead, it uses spread spectrum techniques and lower power operation to achieve adequate transmission range, thereby reducing power consumption while maintaining connectivity.
Solution Approach 2:
The patent moves from a single-frequency transmission approach to a multi-frequency spread spectrum approach. By distributing the signal across a wider frequency spectrum, the system achieves better range and reliability without requiring high power amplification at any single frequency.
