Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elastic solid membrane is used to separate the drive unit from the lancing area, then hygiene is improved, but mechanical resistance increases and power loss increases
Solution Approach 1:
The harmful elastic solid membrane is completely removed from the system. Instead, a liquid seal is introduced that provides the necessary separation without the mechanical resistance and energy loss associated with elastic membranes, while maintaining hygiene through effective separation of the drive unit and lancing area
Solution Approach 2:
A liquid seal is used instead of a solid elastic membrane to separate the drive unit from the lancing area. The liquid provides sealing and hygiene protection while offering minimal mechanical resistance, thereby reducing power loss and improving energy efficiency compared to elastic membrane solutions
2Loss of time
If a depot with large volume is used to store application substance, then refilling frequency is reduced, but substance delivery control deteriorates
Solution Approach 1:
The system incorporates feedback mechanisms where the capillary wick and reservoir design work together to provide controlled substance delivery. The capillary action automatically regulates the flow of application substance from the reservoir to the lancing device, ensuring precise delivery while maintaining a sufficient supply volume to reduce refilling frequency
Solution Approach 2:
A capillary wick made of porous material is used to transport the application substance from the reservoir to the lancing device. The porous structure provides controlled capillary flow that ensures precise substance delivery while the reservoir maintains adequate volume to reduce refilling operations
3Productivity
If resonance drive with high frequency is used, then treatment time is reduced, but clamping security must be increased
Solution Approach 1:
The clamping mechanism is designed with dynamic characteristics that allow it to securely hold the lancing device during high-frequency resonance operation. The mechanical fastening system incorporates features that maintain reliable clamping under the dynamic conditions of resonance drive, enabling high-speed treatment while ensuring safety
