Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing ironing modules use only one temperature or pressure sensor to sense steam state, then the device complexity is reduced, but the manufacturing precision of steam spray amount control deteriorates
Solution Approach 1:
The patent replaces mechanical/physical measurement methods with electronic sensing technology. By using both temperature sensors and pressure sensors to detect steam state, the system achieves precise electronic control of spray amount through controller-based regulation, overcoming the limitations of single-sensor mechanical systems.
Solution Approach 2:
The patent changes the detection parameters from single-parameter (either temperature or pressure) to multi-parameter detection. By simultaneously monitoring both temperature and pressure of steam, the system can precisely determine steam state and adjust spray amount accordingly, resolving the contradiction between device simplicity and control precision.
2Power
If existing ironing modules use a pressure switch to spray high-pressure steam, then the power is increased, but the adaptability to spray steam with various pressures deteriorates
Solution Approach 1:
The patent transforms the static pressure control system into a dynamic one. Instead of using a fixed pressure switch that only activates at a set pressure, the system uses a pressure sensor that continuously monitors steam pressure and allows the controller to dynamically adjust the spray valve, enabling versatile pressure control across a wide range while maintaining high power capability.
Solution Approach 2:
The patent makes the pressure control system universal by replacing the specialized pressure switch with a general-purpose pressure sensor and controller combination. This allows the same system to handle various pressure requirements for different fabric types and spray modes, achieving multi-functionality while maintaining high power output.
3Measurement precision
If existing ironing modules use a pressure sensor to control steam pressure, then the measurement precision is improved, but the reliability of steam spray uniformity deteriorates
Solution Approach 1:
The patent implements a feedback control system where the pressure sensor continuously measures steam pressure and feeds this information back to the controller. The controller adjusts the spray valve in real-time based on this feedback, ensuring uniform steam spray while maintaining high measurement precision. This closed-loop control resolves the reliability issue.
Solution Approach 2:
The patent merges the functions of temperature sensing and pressure sensing into a unified control system. By combining data from both temperature sensors and pressure sensors, the controller achieves comprehensive steam state monitoring, ensuring both precise measurement and reliable uniform spray performance through coordinated control.
4Ease of operation
If existing ironing modules sense temperature and adjust steam amount using temperature, then the ease of operation is improved, but the manufacturing precision of steam control deteriorates
Solution Approach 1:
The patent changes the control parameter from temperature-only to a combination of temperature and pressure parameters. While maintaining the simple temperature-based operation interface, the system now uses both temperature and pressure sensor data for precise steam state determination and spray amount control, resolving the precision limitation.
