Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dispensing systems are used, then the system structure is simple, but the system is not resilient enough for garage environments and leads to cross-contamination
Solution Approach 1:
The system is divided into separate functional components: a container with pierceable membrane, a dosing mechanism with cup feature, and a fluid receptacle. This segmentation allows each component to perform its specific function optimally while maintaining overall system reliability and preventing cross-contamination between different fluids.
Solution Approach 2:
The dosing mechanism acts as an intermediary between the container and fluid receptacle. It includes a cup feature that receives fluid from the container and transfers it to the receptacle, ensuring controlled dosing and preventing direct contact between different fluid sources, thereby preventing cross-contamination.
2Loss of substance
If traditional dispensing systems are used, then the device is simple to operate, but the system does not allow complete emptying of the package and leads to inventory inaccuracies
Solution Approach 1:
Instead of trying to extract fluid from a closed container, the system inverts the approach by having the container with its open end face downward, allowing fluid to flow naturally into the dosing mechanism's cup feature when actuated. This inversion enables complete emptying while maintaining ease of operation through simple actuation.
Solution Approach 2:
The hydrostatic seal in the cup feature automatically prevents air ingress and fluid leakage without requiring active control mechanisms. The system self-regulates fluid flow based on gravity and pressure differential, enabling complete emptying while maintaining operational simplicity.
3Measurement precision
If traditional dispensing systems are used, then the system structure is simple, but the system does not provide accurate fluid measurement
Solution Approach 1:
The system uses visual indicators (such as color-coded coding features or visual measurement markings) to indicate fluid levels and dosing amounts. This provides accurate measurement information to the user without requiring complex electronic sensors or measurement devices.
Solution Approach 2:
The dosing mechanism's cup feature serves as a precise intermediary that controls and measures fluid transfer. Its fixed volume design ensures accurate dosing, while the hydrostatic seal maintains measurement precision by preventing air ingress that would disrupt fluid level readings.
4Reliability
If the open end of the container is submerged in fluid to form a hydrostatic seal, then the seal prevents air ingress and fluid leakage, but the structure becomes more complex
Solution Approach 1:
The system uses hydraulic principles by submerging the container's open end in the fluid within the cup feature to create a hydrostatic seal. The fluid pressure itself provides the sealing force, eliminating the need for mechanical seals or gaskets and maintaining reliability without excessive complexity.
Solution Approach 2:
The hydrostatic seal is a self-regulating system where the fluid pressure automatically adjusts to maintain the seal. When the container is removed or fluid level changes, the seal self-adjusts based on the new pressure differential, providing reliable sealing without requiring active control or complex mechanisms.
