Solution Overview
Problem
Existing medical and dental instrument parts with electrical storage devices face challenges in simplifying the structure for energy supply and communication connections, which often require multiple electrical lines and complex interfaces, leading to space inefficiencies and potential reliability issues.
Innovation Solution
The use of two common electrical lines for both the lighting device and storage device, along with a separate data line for data transmission, simplifies the coupling device and reduces the number of electrical contacts, ensuring reliable energy supply and data transmission while minimizing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate electrical lines are used for lighting device and storage device, then each device can be independently powered, but the number of electrical contacts increases and the coupling device becomes more complex
Solution Approach 1:
The patent combines the power supply for the lighting device and storage device into a single common electrical line, reducing the number of electrical contacts in the coupling device while maintaining independent operation of each device through separate control circuits
Solution Approach 2:
The common electrical line serves multiple functions by providing power to both the lighting device and storage device simultaneously, making the electrical connection system more versatile and reducing overall complexity
2Adaptability or versatility
If multiple electrical lines are used for power supply and data transmission, then all functions can be supported, but the number of electrical contacts increases leading to space inefficiency
Solution Approach 1:
The patent merges power transmission and data transmission functions into a single electrical line by using voltage variations to encode data signals, thereby reducing the number of required electrical contacts and saving space in the instrument component
Solution Approach 2:
The electrical line is designed to perform multiple functions simultaneously - providing both power supply and data communication between the instrument component and external devices, making the system more space-efficient
3Reliability
If wired connections with multiple electrical contacts are used, then reliable power and data transmission can be achieved, but the design becomes less compact and more complex
Solution Approach 1:
The patent combines power and data transmission into a single electrical connection, simplifying the coupling device design and reducing the number of contacts required while maintaining transmission reliability through encoded voltage signals
Solution Approach 2:
The patent replaces complex multi-contact mechanical electrical connections with a simplified single-contact system that uses voltage modulation for data transmission, reducing mechanical complexity while maintaining functionality
