Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional flow limiters are used, then they can limit flow rate, but they fail to maintain consistent and accurate flow rate across varying pressures
Solution Approach 1:
The flow limiter employs a resilient valve element that dynamically adjusts its position in response to pressure changes, allowing the device to maintain accurate and consistent flow rates across varying pressure conditions. The resilient nature of the valve element enables real-time adaptation to pressure fluctuations without requiring complex mechanical adjustments.
Solution Approach 2:
The invention changes the physical state or properties of the valve element by making it resilient rather than rigid. This parameter change allows the valve to flex and adapt to different pressure conditions, maintaining flow rate accuracy and consistency that would be impossible with conventional rigid valve designs.
2Measurement precision
If flow limiters are installed at many locations to determine peak load, then water usage can be accurately determined, but installation and management costs increase
Solution Approach 1:
The flow limiter is designed to autonomously determine and report peak load information without requiring complex external monitoring systems. The device's internal resilient valve mechanism automatically tracks pressure and flow variations, enabling accurate peak load determination while minimizing the need for additional management infrastructure.
3Manufacturing precision
If resilient valve elements are used to maintain constant flow rate, then flow accuracy improves, but device complexity increases
Solution Approach 1:
The invention utilizes a resilient valve element that functions as a flexible component to maintain constant flow rate. This flexible element automatically adjusts to pressure changes without requiring complex mechanical linkages or control systems, achieving high flow rate accuracy while keeping the overall device structure relatively simple.
