Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna and light-emitting element are disposed on different printed boards, then the communication state is maintained, but the device size cannot be reduced
Solution Approach 1:
The patent merges the antenna and light-emitting element onto the same communication board, eliminating the need for separate printed boards and reducing overall device size. The connecting wire connects the light-emitting element to the board while the antenna is disposed on the board, integrating multiple functions into a single substrate.
Solution Approach 2:
The patent introduces a light guide member as an intermediary component that directs light from the light-emitting element away from the antenna. This mediator allows both components to coexist on the same board without the light-emitting element interfering with antenna communication performance.
2Volume of moving object
If the antenna and light-emitting element are disposed on the same board without careful positioning, then device size is reduced, but the communication state deteriorates
Solution Approach 1:
The patent applies local quality by positioning the light-emitting element at a specific location away from the antenna on the communication board. This careful local positioning ensures that the light-emitting element does not interfere with the antenna's communication function while still benefiting from the integrated board design.
Solution Approach 2:
The light guide member serves as a mediator that redirects light away from the antenna region. This intermediary component enables the light-emitting element to be positioned closer to the antenna without compromising communication performance, as the light path is controlled to avoid interfering with the antenna.
3Device complexity
If the light-emitting element is positioned near the antenna, then device complexity is reduced, but electromagnetic interference occurs
Solution Approach 1:
The light guide member acts as an intermediary that controls the light path between the light-emitting element and the antenna. By directing light away from the antenna through this mediator, the system allows close positioning of components without suffering from electromagnetic interference or light interference that would otherwise degrade communication performance.
Solution Approach 2:
The patent extracts the light path control function into a separate light guide member component. This extraction allows the light-emitting element to be positioned independently of the antenna without causing interference, as the light guidance function is handled by a dedicated component that directs light away from the antenna region.
