Engineering Contradiction Analysis
1Reliability
If active base stations are built to compensate for large propagation loss of high-frequency electromagnetic waves, then communication quality is improved, but power consumption and manufacturing cost increase
Solution Approach 1:
The patent employs passive base stations that utilize the natural reflection and transmission properties of the sheet structure without requiring active electronic components or power consumption. The system serves itself by leveraging the inherent electromagnetic wave interaction with the metal units and interconnection units, eliminating the need for powered amplification or signal regeneration at the base station side
Solution Approach 2:
The patent replaces the traditional active electronic system (requiring power amplifiers, signal processing circuits, and active components) with a passive electromagnetic structure. The sheet structure with metal units and interconnection units creates adjustable radiation patterns through controlled electromagnetic reflection and transmission, substituting mechanical/electronic signal manipulation with passive electromagnetic field control

Solution Approach 1:
The patent employs a sheet structure composed of metal units and interconnection units that can be manufactured using cost-effective materials and processes. The design allows for the use of standard metals and simple interconnection structures rather than expensive active electronic components, reducing overall manufacturing cost while maintaining communication quality through passive electromagnetic control
Solution Approach 2:
The patent replaces expensive active electronic systems with a passive electromagnetic structure. The sheet structure with metal units and interconnection units eliminates the need for power amplifiers, signal processing electronics, and other costly active components, achieving communication quality improvement through passive electromagnetic wave manipulation instead of expensive active equipment
3Use of energy by moving object
If a sheet structure with metal units and interconnection units is used to replace active base stations, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent divides the sheet structure into discrete metal units and interconnection units that can be independently designed and controlled. Each unit serves a specific function in the electromagnetic wave interaction, allowing for modular construction and simplified manufacturing while achieving complex radiation pattern control through the coordinated arrangement of these segmented elements
Solution Approach 2:
The patent incorporates controllable interconnection units that can dynamically adjust their electrical characteristics based on control signals. This dynamic capability allows the passive structure to adapt its radiation pattern and impedance characteristics without requiring active electronic components, achieving flexible control while maintaining a relatively simple physical structure
