Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each X-ray unit has a dedicated handheld device, then device pairing reliability is improved, but device complexity and operational inefficiency increase when devices need to be switched
Solution Approach 1:
The patent enables handheld devices to be universally paired with multiple different X-ray units through a standardized pairing protocol, rather than being dedicated to a single unit. This allows any handheld device to be paired with any X-ray unit in the system, providing multi-functionality and eliminating the need for dedicated device-unit assignments.
Solution Approach 2:
The patent implements dynamic pairing where handheld devices can be paired and unpaired with different X-ray units as needed. The pairing status is not fixed but can be changed dynamically through the charging cradle interface, allowing flexible reassignment of devices to units based on operational requirements.
2Ease of operation
If wireless communication is used for device pairing, then ease of operation is improved, but reliability of device recognition deteriorates
Solution Approach 1:
The patent introduces a charging cradle as an intermediary device that facilitates reliable communication between the handheld device and X-ray unit. The cradle receives the handheld device, establishes a stable connection, and mediates the pairing process by transmitting and receiving pairing codes, ensuring accurate device recognition while maintaining ease of operation.
Solution Approach 2:
The patent replaces purely wireless pairing mechanisms with a hybrid approach that uses physical contact through the charging cradle. The mechanical connection of placing the device in the cradle provides a reliable physical basis for communication, supplementing wireless signals and ensuring accurate device recognition.
3Reliability
If additional hardware is added for device pairing, then pairing reliability is improved, but device complexity increases
Solution Approach 1:
The charging cradle is designed to serve multiple functions: it charges the handheld device, facilitates pairing communication, and provides a physical connection interface. By making the cradle multi-functional, the patent avoids the need for separate dedicated pairing hardware, reducing overall system complexity while maintaining pairing reliability.
Solution Approach 2:
The patent combines the pairing functionality with the existing charging cradle infrastructure. Instead of adding separate pairing hardware, the pairing capabilities are merged into the cradle's existing design, allowing it to handle both charging and pairing operations through integrated circuitry and protocols.
