Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operating units are provided to perform varied surgical operations, then the versatility and functional capability of the endoscope device is improved, but the complexity of operation control and the risk of undesired operations increases
Solution Approach 1:
The control unit monitors instruction signals from multiple operating units and provides feedback by detecting abnormal signals. When an abnormal signal is detected, the system responds by stopping transmission of conflicting instructions, thereby preventing undesired operations while maintaining multiple operating capabilities
Solution Approach 2:
The control unit acts as an intermediary between multiple operating units and the endoscope system. It receives instruction signals from various operating units, validates them, and coordinates their execution, preventing direct conflicts between simultaneous operations from different units
2Ease of operation
If multiple operating units are provided to enable easy operation, then the ease of operation is improved, but the reliability of operation control deteriorates due to increased risk of abnormal signals
Solution Approach 1:
The control unit performs preliminary validation of instruction signals before executing operations. By detecting abnormal signals in advance and stopping their transmission, the system prevents undesired operations while maintaining ease of use through multiple operating units
Solution Approach 2:
The system continuously monitors instruction signals from multiple operating units and provides feedback by identifying and blocking abnormal signals, thereby maintaining high reliability while preserving operational ease
3Reliability
If the control unit stops transmission of abnormal instruction signals to prevent undesired operations, then the safety is improved, but the productivity may deteriorate due to operation interruptions
Solution Approach 1:
The control unit mediates between safety requirements and surgical efficiency by selectively blocking only abnormal signals while allowing normal operations to proceed uninterrupted, thus maintaining high productivity alongside improved safety
Solution Approach 2:
The system uses feedback mechanisms to distinguish between abnormal and normal signals, stopping only those that pose safety risks while maintaining continuous operation for valid surgical commands, thereby minimizing interruptions to surgical workflow

AI summary
An endoscope device is proposed for dealing with an erroneous operation of a surgeon. An endoscope device has an endoscope and a processor, wherein the endoscope has a switch unit and the processor has a CPU and an operating panel. In the event that the CPU of the processor detects that, of a first instruction signal transmitted from the switch unit and a second instruction signal transmitted from the operating panel, the instructions for performing the predetermined operation are not performed normally with one of the instruction signals, and instructions for performing an operation other than the predetermined operation is performed normally with the other instruction signal, the CPU stops the transmission of one of the instruction signals, and validates the operation content instructed by the other instruction signal.
