Engineering Contradiction Analysis
1Speed
If conventional reconfiguration controlling apparatuses use fixed light projection methods, then system structure is simple, but reconfiguring speed is slow and precision is insufficient
Solution Approach 1:
The patent implements dynamic control of light projection parameters including variable light intensity, adjustable projection time, and controllable light emission timing. The reproduction-light-causing irradiation control means dynamically adjusts these parameters based on reconfiguration requirements, enabling faster and more precise reconfiguring while maintaining manageable system complexity through controlled dynamic behavior.
Solution Approach 2:
The patent changes multiple light projection parameters simultaneously including light intensity, projection time duration, and timing of light emission. By optimizing these parameters, the system achieves improved reconfiguring speed and precision without requiring fundamentally complex system architecture, as the changes are made within existing operational parameters.
2Manufacturing precision
If light intensity and projection time are increased to improve reconfiguration precision, then manufacturing precision improves, but power consumption increases
Solution Approach 1:
The patent optimizes light projection parameters including light intensity and projection time to achieve the minimum necessary values for precise reconfiguration. By carefully controlling these parameters, the system attains high reconfiguration precision while minimizing power consumption, avoiding the need for continuously high light intensity or extended projection times.
Solution Approach 2:
The patent employs periodic or pulsed light emission rather than continuous illumination. The reproduction-light-causing irradiation means emits light in controlled intervals with specific durations, achieving precise reconfiguration through repeated targeted pulses rather than continuous high-power illumination, thereby reducing overall power consumption while maintaining precision.
3Productivity
If multiple optical patterns are projected simultaneously to increase productivity, then reconfiguring multiple circuits faster, but control complexity increases
Solution Approach 1:
The patent segments the reconfiguration process into multiple optical patterns that can be projected in sequence or parallel. Each optical pattern corresponds to specific circuit reconfiguration tasks, allowing the system to divide complex reconfiguration work into manageable segments that can be handled independently, increasing throughput without overwhelming control complexity.
Solution Approach 2:
The reproduction-light-causing irradiation means is designed with multi-functionality to handle various optical pattern projection requirements. A single irradiation system can project different optical patterns for different reconfiguration scenarios, enabling high productivity through versatile operation rather than requiring separate dedicated systems for each function.

Therefore, optical pattern application can be performed according to the optical control signal at a reconfiguration time adapted to any of various logical operation circuits sequentially reconfigured by the optically reconfigurable gate array. Consequently, correct and reliable write of any one of various types of logical operation circuits can be performed without any write error, and such various types of logical operation circuits can perform logical operation sequentially at high speed.
