Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different types of substrates are used to accommodate different operating voltages and specifications, then the device can support multiple specifications, but the production cost increases due to low volume production of varied substrates
Solution Approach 1:
The patent applies universality by designing a single substrate type that can support multiple light-emitting element arrays with different wiring configurations (series and parallel connections). This allows the same substrate to accommodate different operating voltages and specifications without requiring multiple substrate types, thereby reducing production costs while maintaining specification support capability.
Solution Approach 2:
The patent segments the substrate into multiple independent light-emitting element arrays, each with its own wiring connections. This segmentation allows different arrays to be connected in series or parallel configurations on the same substrate, enabling multiple specifications to be supported using a single substrate type, thus resolving the contradiction between adaptability and manufacturing cost.
2Adaptability or versatility
If multiple different types of substrates are used to accommodate different operating voltages and specifications, then the device can support multiple specifications, but the production complexity increases due to varied substrate requirements
Solution Approach 1:
The patent makes the single substrate universal by incorporating multiple light-emitting element arrays that can be configured in different wiring patterns (series and parallel). This allows one substrate type to fulfill multiple specification requirements, simplifying production processes and reducing the complexity associated with handling multiple substrate types.
Solution Approach 2:
The patent introduces dynamic wiring configurations where the same substrate can be connected in different modes (series or parallel) depending on the required specification. This dynamic adaptability allows a single substrate design to serve multiple purposes, reducing production complexity while maintaining versatility.
3Reliability
If the sealing area is large to cover all light-emitting elements, then all elements are protected, but internal stress increases causing reliability issues
Solution Approach 1:
The patent divides the sealing structure into multiple separate sealing members, each covering a specific light-emitting element array rather than one large continuous seal. This segmentation reduces the internal stress within each sealing member while still providing comprehensive protection for all light-emitting elements, thereby improving reliability by reducing stress-related failures.

AI summary
A light-emitting device includes a substrate, first LEDs and second LEDs mounted on the substrate, multiple wirings separately formed on the substrate, and a conductive member for connecting adjacent two wirings in multiple wirings for establishing series connection, parallel connection, or a combination of series and parallel connections of the first LEDs and the second LEDs. This achieves the light-emitting device that can support multiple different specifications, using a single type of substrate.
