Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the energy applied to the evaporative assistance element is increased to enhance noticeability, then the volatile composition evaporates faster, but the duration of action decreases
Solution Approach 1:
The total emission program implements periodic energy boosts at specific time intervals (first energy boost after 24 hours, second energy boost at 50-60% through the program, third energy boost at 75-80% through the program). This periodic action pattern maintains consumer noticeability by refreshing the volatile composition emission intensity at strategic moments while allowing lower energy operation during extended emission periods, thereby extending the overall duration of action.
2Illumination intensity
If constant high energy is applied to maintain noticeability, then consumer noticeability is improved, but the volatile composition depletes faster
Solution Approach 1:
The system dynamically adjusts the energy applied to the evaporative assistance element based on the progression through the total emission program. Energy levels are varied from low (during extended emission periods) to high (during energy boost periods), creating a dynamic emission pattern that maintains consumer noticeability while conserving volatile composition quantity throughout the multi-week or monthly program duration.
Solution Approach 2:
The total emission program changes the energy parameter of the evaporative assistance element at different stages of the emission cycle. By implementing energy boosts at specific percentages through the program (50-60%, 75-80%) and maintaining lower energy during extended emission periods, the system optimizes the balance between maintaining noticeability and preserving volatile composition quantity.
3Productivity
If the evaporative assistance element operates continuously at high energy, then evaporation rate is maintained, but energy consumption increases
Solution Approach 1:
The evaporative assistance element operates in a periodic pattern with energy boost periods followed by extended emission periods at lower energy levels. This periodic operation maintains adequate evaporation rates during boost periods to ensure noticeability while significantly reducing energy consumption during the extended emission periods that constitute the majority of the total emission program duration.
