Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single lighting area is used to convey device state information, then the device structure remains simple, but the amount of information that can be conveyed is limited
Solution Approach 1:
The lighting area is divided into an outer annular lighting area and an inner lighting area, allowing different device state information to be conveyed simultaneously through different spatial zones. The outer lighting area can display one type of information while the inner lighting area displays another type, thereby increasing information capacity without significantly complicating the overall structure.
Solution Approach 2:
The patent transitions from a single-dimensional lighting display to a two-dimensional annular lighting area with distinct outer and inner zones. This spatial dimensionality change enables multiple pieces of information to be displayed concurrently at different radial positions, effectively increasing information throughput while maintaining structural simplicity.
2Productivity
If multiple lighting areas are used to convey different device state information, then information conveyance efficiency improves, but the device structure becomes more complex
Solution Approach 1:
The annular lighting area is segmented into an outer lighting area and an inner lighting area, each capable of conveying different device state information. This segmentation allows for efficient parallel information conveyance while maintaining a relatively simple integrated structure that does not require separate physical components for each lighting zone.
Solution Approach 2:
The outer and inner lighting areas are merged into a single integrated annular lighting structure rather than being implemented as separate physical components. This merging approach enables multiple information channels while avoiding the structural complexity that would arise from completely separate lighting systems, achieving a balance between information efficiency and structural simplicity.
