Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If omnidirectional scanning mode is used to detect all nearby wireless communication devices, then the completeness of device detection is improved, but the complexity of the device list and difficulty of identifying desired devices increases
Solution Approach 1:
The patent segments the scanning process into two distinct modes: omnidirectional scanning for comprehensive device discovery, and directional scanning for focused device identification. The processor divides the scanning function into different operational states, allowing users to first obtain a complete list of available devices through omnidirectional scanning, then selectively identify desired devices using directional scanning with body orientation input, thus resolving the contradiction between detection completeness and list complexity.
Solution Approach 2:
The patent introduces a new dimension for device identification by incorporating spatial orientation through body scanning. Instead of relying solely on device names and basic information in a flat list, the system adds spatial positioning and directional information as a new dimension, allowing users to identify devices based on their physical location and orientation relative to the user's body, thereby simplifying the identification process while maintaining detection completeness.
2Reliability
If omnidirectional scanning mode is used to detect all nearby wireless communication devices, then the completeness of device detection is improved, but the time required to identify and connect to desired devices increases
Solution Approach 1:
The patent segments the device identification process into two phases: Phase 1 uses omnidirectional scanning to build a complete database of available devices, and Phase 2 uses directional scanning with body orientation to quickly identify the desired device. This segmentation eliminates the need to manually search through the entire device list, significantly reducing the time required to connect while preserving detection completeness.
Solution Approach 2:
The system performs preliminary omnidirectional scanning to pre-load a complete list of available devices into memory before the user needs to connect. This preliminary action ensures that when the user initiates a connection, the device is already identified and ready, eliminating delays associated with real-time scanning and device search, thus reducing connection time while maintaining complete device detection capability.
3Ease of operation
If directional scanning mode based on body orientation is used, then the ease of identifying desired devices is improved, but the coverage area for device detection is reduced
Solution Approach 1:
The patent segments the scanning coverage into two functional areas: a wide omnidirectional scanning zone for comprehensive device discovery, and a focused directional scanning zone for precise device identification. The system intelligently switches between these segmented scanning zones based on user needs, allowing easy device identification through body orientation while maintaining the option for broader coverage when necessary.
Solution Approach 2:
The patent implements dynamic scanning coverage that adapts to user actions. The scanning area dynamically expands to omnidirectional coverage during initial device discovery phases, then contracts to a focused directional beam aligned with user body orientation during device selection phases. This dynamic adjustment of coverage area optimizes both ease of identification and detection capability at different stages of the connection process.
