Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are positioned on a folding device to support different wireless protocols, then wireless protocol compatibility is improved, but antenna obstruction and interference occur in folded orientation reducing wireless performance
Solution Approach 1:
The patent implements dynamic antenna configuration where the antenna system automatically adapts its operational state based on the device's physical configuration. Sensors detect whether the folding device is in open or folded state, and the system dynamically switches between different antenna subsets accordingly. This resolves the contradiction by making the antenna system flexible and adaptive rather than static, allowing full utilization of multiple antennas in open state for protocol compatibility while switching to optimized subsets in folded state to maintain wireless performance.
Solution Approach 2:
The system changes operational parameters of the antenna system based on device configuration state. In open configuration, all antennas operate across multiple frequency bands and protocols. In folded configuration, the system modifies parameters by disabling certain antennas or adjusting their operational frequencies to minimize interference and obstruction. This parameter adaptation allows the system to maintain protocol compatibility when needed while optimizing performance in folded state.
2Adaptability or versatility
If antenna functionality is maintained in folded configuration, then wireless protocol support is preserved, but signal obstruction and interference increase due to limited space
Solution Approach 1:
The patent segments the antenna system into multiple independent antenna elements that can be selectively activated. Rather than treating the antenna system as a single unified component, the device divides it into separate antenna subsets that can be independently controlled. In folded configuration, the system activates only the antenna segments that are not obstructed or interfering, while keeping protocol support intact through the remaining active segments. This segmentation allows the system to maintain versatility while avoiding the harmful effects of obstruction and interference.
Solution Approach 2:
Different antenna elements are assigned different functional roles and operational characteristics based on their physical locations and performance in various device configurations. The system applies local quality by optimizing each antenna's contribution based on its specific performance characteristics in open versus folded states. This allows the system to maintain overall protocol support while locally optimizing each antenna's operation to minimize obstruction and interference effects.
3Reliability
If all antennas are activated in open configuration, then wireless performance is optimized, but resource consumption increases
Solution Approach 1:
The system applies partial action by activating only the necessary subset of antennas required for current operational needs rather than continuously activating all antennas. In open configuration, the system activates all antennas when full wireless performance is required, but can selectively reduce activation based on actual protocol requirements and signal conditions. This partial activation approach maintains optimized performance when needed while reducing resource consumption during normal operation or when fewer protocols are required.
