Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If conventional air filters are used with consistent materials and dense folding structures, then filtration function is provided, but resistance increases over time leading to short service life and high replacement frequency
Solution Approach 1:
The patent applies dynamics by making the filter material structure adjustable and changeable during operation. The filter can switch between different folding structures (dense, loose, extended) to adapt to different filtration stages and resistance levels, transforming a static filter into a dynamic system that evolves with usage conditions to maintain optimal performance
Solution Approach 2:
The patent changes physical parameters of the filter material including folding density, surface area, and structural configuration. By adjusting these parameters during operation (switching between dense folding for high filtration and loose/extended folding for low resistance), the system optimizes the balance between filtration efficiency and air flow resistance throughout the filter's service life
2Reliability
If 3-stage series combined filtration mode is adopted to improve filtration efficiency, then air quality improves, but total resistance reaches 1700 Pa causing high energy consumption
Solution Approach 1:
The patent segments the filtration process into multiple adjustable stages within a single filter unit. Instead of using three separate fixed filters in series, one filter with adjustable structures performs sequential filtration tasks, dividing the overall filtration function into manageable segments that can be optimized independently for both efficiency and resistance control
Solution Approach 2:
The patent makes a single filter unit perform multiple functions that traditionally required three separate filters. The filter can switch between dense folding mode for high-efficiency filtration and loose/extended folding mode for low-resistance air flow, providing universal functionality that covers both high filtration efficiency and low energy consumption requirements
3Device complexity
If conventional single-use air filter units are used, then simple structure is maintained, but high cost of consumables and manual maintenance occurs
Solution Approach 1:
The patent implements self-service through automatic control systems that monitor filter resistance and automatically adjust the folding structure or trigger cleaning/maintenance cycles. This reduces the need for manual intervention and monitoring, allowing the filter to maintain itself and optimize performance automatically throughout its extended service life
