Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If antenna modules are positioned at diagonally opposed corner portions, then omnidirectional sensing capability is improved, but device complexity increases
Solution Approach 1:
The sensing system is segmented into multiple independent antenna modules positioned at different corner portions of the housing. Each antenna module independently performs electromagnetic signal transmission and induction signal generation, allowing the system to achieve omnidirectional sensing capability through spatial distribution rather than a single complex sensing unit.
Solution Approach 2:
The antenna modules serve dual functions: they transmit and receive electromagnetic wave signals for communication while simultaneously generating induction signals for sensing subject approach. This merging of communication and sensing functions into the same components reduces overall device complexity while maintaining omnidirectional capability.
2Adaptability or versatility
If multiple antenna modules are used for omnidirectional sensing, then sensing coverage is improved, but manufacturing cost increases
Solution Approach 1:
The antenna modules are designed with universal functionality to perform both communication (electromagnetic signal transmission) and sensing (induction signal generation for subject detection). By using the same components for multiple purposes, the patent avoids the need for separate dedicated sensing hardware, thereby reducing manufacturing cost while maintaining comprehensive sensing coverage.
3Measurement precision
If antenna modules are placed at corner portions, then sensing accuracy is improved, but device size increases
Solution Approach 1:
The patent utilizes the three-dimensional space of the device housing by positioning antenna modules at corner portions rather than spreading them across the surface area. This spatial arrangement in three dimensions achieves omnidirectional sensing coverage and improved sensing accuracy without proportionally increasing the device's footprint, as the corners are naturally part of the device's boundary geometry.
