Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional air compression leg massagers use traditional host designs with separate connecting pipes, then the device can provide reliable air compression function, but the device becomes heavy and bulky
Solution Approach 1:
The patent integrates the solenoid valve assembly directly into the air distribution bracket, merging the valve housing and air distribution function into a single integrated component. This eliminates the need for separate connecting pipes and reduces the number of parts, thereby decreasing device weight and simplifying the overall host structure while maintaining reliable air compression functionality.
Solution Approach 2:
The air distribution bracket serves multiple functions: it acts as the structural support for the solenoid valves, provides the air distribution channels, and eliminates the need for separate connecting pipes. This multi-functional design reduces the number of components required, leading to a lighter and less complex device structure.
2Ease of operation
If conventional air compression leg massagers use traditional host designs, then the device can provide stable air compression, but the device is bulky and inconvenient to use
Solution Approach 1:
By merging the solenoid valve assembly and air distribution bracket into an integrated unit, the patent reduces the overall host volume. This compact design improves device portability and ease of operation while maintaining stable air compression functionality through the efficient integrated structure.
3Volume of stationary object
If the solenoid valve assembly uses a simplified integrated design, then the device becomes compact and portable, but air passage control complexity increases
Solution Approach 1:
The patent segments the air passages into distinct first and second rows, with each solenoid valve controlling specific passages. This segmentation approach organizes the complex air control logic into manageable sections, making the integrated design more controllable while maintaining compact dimensions.
Solution Approach 2:
Different regions of the air distribution bracket are assigned different functions: the first row of solenoid valves controls the first row of air passages, while the second row controls the second row of passages. This localized functional assignment simplifies the control logic within the compact integrated structure.
