Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cassette performs a confirmation operation to check if a coin remains, then the reliability of coin detection is improved, but the time required for coin transfer increases
Solution Approach 1:
The system performs preliminary actions by checking the inventory amount stored in the cassette's memory before initiating the confirmation operation. When the inventory amount is 0, the system skips the confirmation operation entirely, avoiding unnecessary time consumption while maintaining reliability through the memory data.
Solution Approach 2:
The system dynamically adjusts its behavior based on the inventory amount. When inventory is 0, it skips confirmation and directly supplies coins. When inventory is not 0, it performs confirmation operation. This dynamic decision-making optimizes the balance between reliability and time efficiency.
2Reliability
If the system always performs confirmation operation, then the reliability of coin detection is improved, but the productivity of coin transfer decreases
Solution Approach 1:
The system uses the inventory amount stored in memory as a preliminary indicator to decide whether to perform confirmation operation. This preliminary check allows the system to skip unnecessary confirmation steps when inventory is 0, thereby improving productivity without sacrificing reliability.
Solution Approach 2:
The system changes its operational parameters based on the inventory amount. When inventory is 0, it changes the confirmation operation parameter to 'skip'. When inventory is not 0, it changes to 'perform'. This parameter change strategy optimizes the balance between reliability and productivity.
3Loss of time
If the system skips confirmation operation, then the coin transfer time is reduced, but the reliability of detecting remaining coins deteriorates
Solution Approach 1:
The system uses feedback from the inventory amount stored in the cassette's memory to determine whether to perform confirmation operation. This feedback mechanism allows the system to make informed decisions about skipping confirmation while maintaining acceptable reliability levels.
Solution Approach 2:
The inventory amount in memory serves as a preliminary indicator that guides the decision to skip or perform confirmation. This preliminary action based on memory data reduces unnecessary time consumption while maintaining reliability through the pre-stored inventory information.
4Reliability
If the system performs second confirmation operation after error, then the reliability of coin supply is improved, but the complexity of error handling increases
Solution Approach 1:
The system uses feedback from error detection during coin supply to determine when to perform second confirmation operation. This feedback mechanism ensures reliable coin supply by verifying coin presence after errors occur, while the structured approach keeps complexity manageable.
Solution Approach 2:
The system prepares for potential errors by implementing a second confirmation operation that can be triggered when errors are detected during supply. This beforehand cushioning ensures reliability by having a backup verification mechanism in place.

AI summary
A coin handling apparatus includes the following: a cassette attachment unit where a cassette is detachably attached; a coin supply unit that supplies a coin to the cassette; and a control unit that causes the cassette attached to the cassette attachment unit to perform a first confirmation operation for confirming that a coin remains in the cassette when the cassette does not satisfy a predetermined condition, and operates the coin supply unit to supply a coin to the cassette attached to the cassette attachment unit without causing the cassette to perform the first confirmation operation when the cassette satisfies the predetermined condition.
