Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If time-dependent tower switching is used in conventional adsorption-type dehumidification apparatuses, then continuous dehumidification productivity is maintained, but renewable energy consumption increases and adsorbent utilization deteriorates
Solution Approach 1:
The patent applies dynamics by switching from fixed time-dependent tower switching to flow rate-dependent switching. The control unit dynamically adjusts the switching timing between adsorption and regeneration processes based on real-time flow rate measurements, allowing the system to adapt its operation to actual demand conditions and optimize energy consumption while maintaining productivity.
Solution Approach 2:
The patent implements feedback by using a flow rate sensor to continuously monitor the flow rate of compressed air and feeding this information back to the control unit. The control unit then adjusts the switching timing of adsorption and regeneration processes based on this feedback, creating a closed-loop control system that optimizes both productivity and energy efficiency.
2Device complexity
If fixed adsorbent quantity is used in adsorption towers, then device structure is simplified, but adsorbent utilization deteriorates and lifespan is reduced
Solution Approach 1:
The patent applies dynamics by enabling flexible utilization of adsorbent capacity through flow rate-dependent switching. Instead of being constrained by fixed time intervals, the system dynamically adjusts regeneration timing based on actual flow rate conditions, allowing more complete utilization of adsorbent capacity and extending adsorbent lifespan without modifying the physical structure of the adsorption towers.
3Ease of operation
If regeneration process is performed at fixed intervals, then process control is simplified, but energy efficiency deteriorates
Solution Approach 1:
The patent implements feedback by using flow rate sensor data to dynamically control the regeneration process timing. The control unit receives real-time flow rate information and adjusts the switching between adsorption and regeneration processes accordingly, optimizing energy efficiency by performing regeneration only when necessary based on actual operational conditions rather than following a fixed schedule.
Solution Approach 2:
The patent applies parameter changes by using flow rate as a dynamic control parameter for switching between processes. Instead of using fixed time intervals, the system changes the switching parameter from time-based to flow rate-based, allowing the regeneration process to be triggered by actual demand conditions and thereby improving energy efficiency.
