Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hardware alterations are made to adjust transmission range, then transmission range can be changed, but device complexity and cost increase
Solution Approach 1:
The patent implements dynamic transmission power adjustment through software control mechanisms. The wireless communication device can modify its transmission power level in real-time based on detected signal properties at boundary positions, eliminating the need for physical hardware alterations while achieving adaptable transmission range control.
Solution Approach 2:
The invention changes the transmission parameter (power level) dynamically through software rather than hardware modification. By adjusting the power level parameter based on feedback from boundary devices, the system achieves range control without increasing device complexity or requiring additional hardware components.
2Adaptability or versatility
If higher-gain transmission antenna is substituted to increase transmission range, then transmission range increases, but device complexity and cost increase
Solution Approach 1:
Instead of substituting physical antennas, the patent adjusts the transmission power parameter dynamically. This allows the same antenna to achieve extended effective range by increasing power output rather than requiring a higher-gain antenna, thereby avoiding additional hardware complexity and cost.
3Adaptability or versatility
If specialty wall or window films are used to prevent wireless signal from escaping, then transmission range is limited, but cost and implementation complexity increase
Solution Approach 1:
The patent replaces the mechanical/physical solution (specialty films on walls) with an electronic/software-based solution. Boundary devices detect signal properties and provide feedback to control transmission power, achieving signal containment through intelligent control rather than physical barriers, thereby reducing implementation complexity and cost.
4Adaptability or versatility
If transmission power is increased to extend signal range, then signal strength at boundary increases, but interference with other signals increases
Solution Approach 1:
The patent implements a feedback mechanism where boundary devices continuously monitor signal properties and transmission power levels. Based on this feedback, the wireless communication device adjusts its transmission power dynamically, reducing power when boundaries are approached to minimize interference while maintaining adequate signal strength for legitimate users, thus balancing range extension with interference reduction.
