Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If shorter wavelength frequency bands are used to provide faster broadband connections, then connection speed is improved, but signal reliability deteriorates due to easier blockage and narrower beams
Solution Approach 1:
The patent introduces a reflective surface as an intermediary element to relay signals between the access point and user device. This mediator enables the signal to reach the destination by reflecting off the surface, providing an alternative path that overcomes direct blockages and maintains connection reliability while using higher frequency bands for speed
Solution Approach 2:
The patent transitions from traditional direct-line-of-sight three-dimensional spatial communication to two-dimensional surface-based reflection communication. By utilizing the reflective surface as an intermediate medium, the system creates a new communication dimension that bypasses blockages and expands coverage areas for high-frequency signals
2Loss of energy
If narrower beams are used to provide more focused signal transmission, then energy efficiency is improved, but coverage area deteriorates
Solution Approach 1:
The patent extends coverage by utilizing the reflective surface as an intermediate medium, effectively transforming limited direct beam coverage into expanded reflected coverage. The narrow beam maintains energy efficiency while the reflection off the surface extends the coverage area to regions that would otherwise be unreachable
Solution Approach 2:
The patent divides the coverage area into direct path zones and reflected path zones. The narrow beam serves the direct path efficiently, while the reflective surface handles the reflected path coverage, allowing the system to maintain energy efficiency while achieving comprehensive coverage through segmented transmission paths
