Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-segmented first conductive member is used as an antenna radiator, then communication quality is maintained across multiple frequency bands, but grip sensing accuracy deteriorates due to the inability to distinguish antenna regions from non-antenna regions
Solution Approach 1:
The conductive member is divided into two distinct parts: a first conductive member serving as an antenna radiator and a second conductive member dedicated to grip sensing. This segmentation allows each component to perform its specific function independently, resolving the conflict between maintaining communication quality and achieving accurate grip sensing.
Solution Approach 2:
The grip sensing function is extracted from the antenna structure by introducing a separate second conductive member. This extraction enables the grip sensing operation to be performed independently from the antenna radiation function, eliminating the interference between the two functions.
2Adaptability or versatility
If multiple antennas are disposed to support various communication bands, then communication coverage is improved, but device space is insufficient leading to potential performance degradation
Solution Approach 1:
The first conductive member is designed to function as a multi-band antenna radiator, capable of supporting various communication bands (low band, mid band, high band) simultaneously. This multi-functionality allows the device to achieve broad communication coverage without requiring multiple separate antennas, thus saving device space.
