Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power is always supplied to photodiodes or TFTs to maintain immediate operational readiness, then workflow efficiency is improved, but power consumption increases and component lifetime is reduced
Solution Approach 1:
The control unit stores operation state information in advance before battery charging or replacement occurs. When the battery is recharged or replaced, the system automatically restores the previous operation state without requiring manual intervention or prolonged power supply, thereby maintaining workflow efficiency while reducing power consumption during battery maintenance periods.
Solution Approach 2:
The system implements periodic power supply management by switching between different operation states (imaging ready, imaging standby, imaging stop) based on imaging requirements and battery status. This periodic switching allows the system to maintain operational readiness when needed while conserving power and reducing component stress during non-critical periods.
2Reliability
If power is always supplied to photodiodes or TFTs, then operational stability is maintained, but component deterioration accelerates and device lifetime is shortened
Solution Approach 1:
The system dynamically adjusts the power supply state to photodiodes and TFTs based on actual imaging needs and battery status. Instead of continuous power supply, the system transitions between imaging ready, imaging standby, and imaging stop states, thereby maintaining operational stability when required while reducing component stress and extending device lifetime during non-imaging periods or battery maintenance.
Solution Approach 2:
The control unit monitors imaging operation status and battery charge status in real-time, using this feedback information to automatically adjust power supply to photodiodes and TFTs. This feedback mechanism ensures operational stability is maintained during imaging while preventing unnecessary power supply that would accelerate component deterioration.
3Reliability
If battery is charged or replaced during continuous imaging operation, then power supply continuity is maintained, but workflow efficiency is reduced due to system downtime
Solution Approach 1:
The control unit stores the operation state information in advance before battery charging or replacement begins. This preliminary action ensures that when the battery is recharged or replaced, the system can immediately restore the previous operational state without manual intervention or extended downtime, thereby maintaining power supply continuity while minimizing workflow disruption.
