Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to switch between lighting and projection modes, then device complexity is reduced, but user convenience deteriorates due to multiple manual steps required
Solution Approach 1:
The system automatically detects user actions (phone removal, projector activation) and autonomously switches between lighting and projection modes without requiring manual user intervention. The processing unit monitors sensor inputs and external device states to trigger mode transitions, making the system self-serve the user's needs.
Solution Approach 2:
The system continuously monitors user behavior through sensors (detecting phone removal, body presence) and external device signals (projector activation status), using this feedback to automatically adjust lighting modes. This closed-loop feedback mechanism enables automatic mode switching based on real-time user context.
2Ease of operation
If automatic mode switching is implemented, then user convenience is improved, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The processing unit serves multiple functions: it controls both lighting and projection modes, processes sensor data, communicates with external devices, and manages mode transitions. By making the processing unit universal and multi-functional, the patent avoids adding separate dedicated controllers for each function, thereby limiting the increase in device complexity.
3Ease of operation
If lighting remains on during projection mode, then user convenience is improved, but energy consumption increases
Solution Approach 1:
The lighting system dynamically adjusts its operation based on the active mode. In projection mode, the lighting automatically transitions to a dimmed or off state, while in lighting mode, it operates at full brightness. This dynamic adaptation allows the system to optimize energy consumption based on real-time operational requirements.
4Loss of energy
If manual light adjustment is required during video watching, then energy savings are improved, but time consumption increases due to multiple manual steps
Solution Approach 1:
The system proactively detects when a projector is activated or when the user leaves the room, and automatically adjusts the lighting state in advance before the user would need to manually intervene. This preliminary action eliminates the need for users to perform manual adjustment steps, saving both time and energy.
