Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple output circuits are added to indicate internal states, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Light-emitting circuits are introduced as intermediary elements between the internal circuit components and the user. These light-emitting circuits convert internal electrical states into visible light signals, serving as a mediator that bridges the gap between the device's internal operations and user observation, allowing users to confirm operational status without direct inspection of internal components
Solution Approach 2:
The patent utilizes light emission (color change) from the light-emitting circuits to indicate different operational states. By varying the illumination status of these light-emitting elements, the device communicates its internal state through visual color or light presence/absence changes, enabling intuitive user understanding of complex internal conditions
2Ease of operation
If light-emitting circuits are used for status indication, then ease of operation is improved, but use of energy increases
Solution Approach 1:
Instead of continuously illuminating all light-emitting circuits, the system activates only the specific light-emitting circuits corresponding to the current operational state or anomaly detection. This partial action approach reduces overall energy consumption while maintaining effective status indication, as only necessary light-emitting elements are powered at any given moment
Solution Approach 2:
The light-emitting circuits can be activated periodically or on-demand rather than continuously, allowing the device to enter low-power states when status monitoring is not immediately required. This periodic illumination strategy maintains the ability to indicate operational status while significantly reducing average energy consumption compared to continuous operation
