Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If liquid is stored in the tank for extended periods, then the tank can supply liquid to multiple printers over time, but the liquid becomes stagnant and develops non-uniform temperature and concentration distributions
Solution Approach 1:
The agitator performs periodic agitation operations at predetermined intervals to mix the liquid in the tank. This periodic action prevents the liquid from becoming stagnant and maintains uniform temperature and concentration distributions throughout the stored liquid, resolving the contradiction between extended storage duration and liquid uniformity.
2Stability of the object's composition
If the agitator operates continuously to maintain liquid uniformity, then the liquid remains well-mixed, but the agitation motor consumes excessive energy and has reduced lifespan
Solution Approach 1:
Instead of continuous operation, the agitation motor operates periodically at predetermined intervals. This approach maintains liquid uniformity by agitating the liquid at sufficient intervals while allowing the motor to rest between operations, thereby reducing overall energy consumption and extending motor lifespan.
Solution Approach 2:
The agitator performs agitation operations at predetermined intervals that are sufficient to maintain liquid uniformity without being excessive. This partial action approach achieves the necessary mixing effect while avoiding the energy waste and motor wear associated with continuous operation.
3Stability of the object's composition
If components like titanium oxide settle in the ink, then the liquid becomes non-uniform, but continuous agitation prevents settling while increasing energy consumption
Solution Approach 1:
The agitation system operates periodically at predetermined intervals to prevent component settling. This periodic agitation is sufficient to keep components like titanium oxide uniformly distributed in the ink without the excessive energy loss associated with continuous agitation, as the intervals are optimized to maintain uniformity while minimizing energy consumption.
