Innovation Solution
The solution involves a lighting device and power input assembly configuration with keying regions, electrical connector regions, and engagement structures that allow for a single-step electrical and optional mechanical connection by moving the lighting device relative to the power input assembly, utilizing spring elements and positioning elements for secure alignment and holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical connector apparatus are used, then reliable electrical connection can be achieved, but the connection process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple functions (alignment, electrical connection, and mechanical attachment) into a single integrated connector apparatus. The connector includes alignment features that guide proper positioning, electrical contacts that establish electrical connection, and a mechanical attachment mechanism all in one component, allowing simultaneous achievement of reliable electrical connection and easy single-step installation
Solution Approach 2:
The connector apparatus incorporates pre-configured alignment features and contact arrangements that are prepared in advance. The alignment features protrude from the connector body, and the electrical contacts are pre-positioned, so that when the connector is inserted, the alignment features first guide the connection, followed by automatic engagement of electrical contacts, eliminating the need for separate alignment and connection steps
2Reliability
If traditional electrical connector apparatus are used, then reliable electrical connection can be achieved, but the apparatus cannot be connected in small spaces
Solution Approach 1:
The connector apparatus is designed with a compact, nested structure where the alignment features are integrated into the body of the connector rather than being separate components. The electrical contacts are arranged in a space-efficient configuration within the connector housing, allowing the entire assembly to fit in small spaces while maintaining reliable connection functionality
3Reliability
If traditional electrical connector apparatus are used, then reliable electrical connection can be achieved, but the apparatus becomes complex and difficult to manufacture
Solution Approach 1:
The patent integrates multiple functions (alignment, electrical connection, and mechanical attachment) into a single connector apparatus that can be manufactured as one piece or pre-assembled unit. This consolidation reduces the number of separate components that need to be manufactured and assembled, simplifying the manufacturing process while maintaining reliable electrical connection through the integrated design
