Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light emitting diode, circuit board, and wires are assembled separately with complex electrical connections, then the electrical connection is achieved, but the assembly time is long and manufacturing cost is high
Solution Approach 1:
The patent merges the light emitting diode, circuit board, and wires into an integrated module where the light emitting diode is directly mounted on the circuit board and electrically connected without separate wire connections. This integration eliminates the need for separate assembly steps and complex wiring, thereby reducing assembly time while maintaining reliable electrical connection.
Solution Approach 2:
The patent segments the bulb into distinct functional modules: a lighting unit module containing the light emitting diode and circuit board as an integrated assembly, and a housing module. This modular segmentation allows the integrated lighting unit to be manufactured and tested separately, then quickly assembled into the final product, reducing overall assembly time while preserving electrical reliability.
2Reliability
If the light emitting diode, circuit board, and wires are assembled separately with complex electrical connections, then the electrical connection is achieved, but the manufacturing cost is high
Solution Approach 1:
The patent combines the light emitting diode and circuit board into an integrated lighting unit module, eliminating the need for separate wire connections and complex assembly processes. This integration simplifies manufacturing procedures, reduces the number of components to be managed, and lowers manufacturing costs while maintaining reliable electrical connection.
Solution Approach 2:
The patent performs preliminary integration of the light emitting diode and circuit board into a pre-assembled lighting unit module that can be manufactured and tested independently before final assembly into the bulb. This preliminary action allows for standardized production of the integrated module, reducing manufacturing complexity and cost while ensuring reliable electrical connections are established during module fabrication rather than during final bulb assembly.
3Reliability
If the light emitting diode, circuit board, and wires are assembled separately, then the electrical connection can be established, but the assembly process is complex
Solution Approach 1:
The patent merges the light emitting diode, circuit board, and electrical connections into a single integrated lighting unit module. This consolidation eliminates the complex separate assembly process of connecting wires between discrete components, as the electrical connections are established during module fabrication. The simplified module can then be easily installed into the bulb housing, reducing assembly process complexity while maintaining reliable electrical connection.
Solution Approach 2:
The patent segments the overall bulb into two main parts: an integrated lighting unit module containing the light emitting diode and circuit board with pre-established electrical connections, and a housing module. This segmentation reduces assembly process complexity by transforming a multi-step process of connecting separate components into a simple insertion or mounting operation of the pre-integrated module into the housing.

AI summary
A light emitting diode bulb includes a driving circuit board, a lighting unit, and a housing. The driving circuit board has one or more extending parts formed on one side, and a group of electrically connecting pins are disposed on the other side. An electrode is attached to one surface of each of the extending parts. The lighting unit is electrically connected to the electrodes. The housing packages the driving circuit board and the lighting unit, the electrically connected pins extend beyond the housing. The light emitting bulb has advantages of easy manufacture and low cost since the driving circuit board is electrically connected to the lighting unit directly and the housing then packages the driving circuit board and the lighting unit.
