Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used to transmit operation instructions, then remote control capability is improved, but transmission delays occur due to communication interference
Solution Approach 1:
The system performs preliminary actions by calculating multiple candidate target values in advance before transmission. The wireless communication apparatus computes several possible target values based on current state information, and transmits these pre-calculated values to the control target apparatus. This allows the control target apparatus to immediately select and execute an appropriate target value without waiting for delayed transmission responses, thereby reducing the impact of communication delays on operation timing.
2Ease of operation
If wireless communication is used to transmit operation instructions, then remote control capability is improved, but operation consistency deteriorates due to communication state variations
Solution Approach 1:
The system changes parameters by transmitting multiple candidate target values with different parameter settings instead of a single target value. The wireless communication apparatus generates several target values with varying parameters (such as different position coordinates, speed values, or timing parameters), allowing the control target apparatus to select the most appropriate one based on current communication conditions and operational requirements, thereby maintaining operation consistency despite communication variations.
Solution Approach 2:
The system implements feedback mechanisms where the control target apparatus transmits state information back to the wireless communication apparatus. This feedback loop allows the system to continuously monitor communication states and operational outcomes, enabling dynamic adjustment of target value transmission strategies. Based on received state information and communication quality, the system can adaptively modify which candidate target values are transmitted and how they are selected, ensuring consistent operational performance.
3Reliability
If multiple candidate target values are transmitted, then operation reliability is improved, but communication data volume increases
Solution Approach 1:
The system applies partial action by transmitting a limited set of candidate target values (e.g., 2-3 carefully selected candidates) rather than transmitting all possible target values. This selective transmission approach provides sufficient redundancy to handle communication failures and maintain operation reliability, while avoiding the excessive data volume that would result from transmitting every possible target value. The system transmits only the necessary number of candidates based on operational requirements and communication constraints.

AI summary
According to one embodiment, an electronic apparatus includes a receiver, a processor and a transmitter. The receiver receives a reception signal including a value indicating a physical quantity related to operation of a control target object at a communication destination. The processor determines a state of wireless communication between the electronic apparatus and the communication destination. The processor calculates a target value for instructing operation of the control target object. The processor generates a transmission signal including a value obtained by modifying the target value. The transmitter transmits the transmission signal to the control target object.
