Innovation Solution
The infusion device is designed with a modular structure comprising an L-shaped liquid storage device and infusion pump connected via a slide rail system, featuring guide rails and tracks with snap-fit mechanisms, and includes snap-fit and snap-lock connections for easy assembly and disassembly, along with waterproof seals to achieve IPX8 level protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the infusion device uses a non-modular structure, then the device structure is simple, but the assembly and disassembly become cumbersome
Solution Approach 1:
The infusion device is divided into modular components including a pump unit and a liquid storage device that can be independently assembled and disassembled. The pump unit contains motor, drive mechanism, and control electronics, while the liquid storage device holds the infusate, creating separable functional modules that improve assembly convenience without excessive complexity
Solution Approach 2:
The pump unit is designed as a universal module that can work with different liquid storage devices through standardized connection interfaces. This multi-functional design allows the same pump unit to serve multiple purposes with different reservoirs, simplifying the overall system while maintaining ease of assembly and disassembly
2Reliability
If the infusion device lacks waterproof sealing, then the structure is simpler, but the waterproof performance is insufficient
Solution Approach 1:
Flexible waterproof sealing rings made of elastomeric materials are installed at the connection interfaces between the pump unit and liquid storage device. These thin film seals conform to the mating surfaces and prevent water ingress while maintaining a relatively simple overall structure
Solution Approach 2:
The connection interface combines rigid structural components with flexible sealing materials to create a composite joint that provides both mechanical strength and waterproof sealing. The rigid parts maintain structural integrity while the flexible seals provide water protection
3Ease of operation
If the infusion device uses a modular structure, then the assembly and disassembly become convenient, but the device structure becomes more complex
Solution Approach 1:
The device is segmented into standardized modules with defined interfaces, allowing convenient assembly and disassembly while keeping each module's internal structure relatively simple and manageable
Solution Approach 2:
Universal connection interfaces are designed to work across different module combinations, reducing the need for multiple specialized connection mechanisms and thereby limiting the increase in overall structural complexity
4Reliability
If the infusion device lacks waterproof design, then the manufacturing is simpler, but the waterproof performance deteriorates
Solution Approach 1:
Pre-formed flexible sealing rings are installed into grooves at the connection interfaces during assembly, providing waterproof sealing without requiring complex waterproof manufacturing processes for the main device components
Solution Approach 2:
The sealing effectiveness is achieved by controlling the compression parameter of the elastomeric sealing rings, which deform under assembly pressure to fill microscopic gaps and create waterproof seals through material property rather than geometric complexity
