Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual welding is used to connect wires to the lamp cap, then secure electrical connections are achieved, but production efficiency is reduced and assembly complexity increases
Solution Approach 1:
The patent merges the wire connection function directly into the lamp cap structure by forming contact pads on the lamp cap that directly contact the PCB pads, eliminating the need for separate wire connections and manual welding operations. This integration maintains electrical connection security while enabling automated assembly.
Solution Approach 2:
The patent extracts the wire and welding operations from the assembly process by designing the lamp cap with integrated contact pads that directly interface with the PCB, removing the intermediate wiring step and enabling direct automated mounting of the lamp cap to the PCB.
2Extent of automation
If additional connectors are added to avoid manual welding, then assembly automation is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the electrical connection function into the existing lamp cap and PCB structures by forming contact pads on both components, eliminating the need for additional connectors or intermediate components. This integration achieves assembly automation while maintaining simple device architecture.
Solution Approach 2:
The lamp cap serves multiple functions: it provides the electrical connection interface through its contact pads, maintains the structural housing function, and enables automated assembly through its direct-mount design. This multi-functionality eliminates the need for separate connector components.
3Extent of automation
If additional connectors are added to avoid manual welding, then assembly automation is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the connection function into the base lamp cap and PCB structures, eliminating the need for additional connector components. This reduces part count and manufacturing cost while enabling automated assembly through direct mounting of the lamp cap to the PCB.
Solution Approach 2:
The patent uses simple, inexpensive contact pads formed directly on the lamp cap and PCB instead of expensive additional connectors. These integrated contact features are manufactured as part of the base components, reducing overall manufacturing cost.
