Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED light strips face limitations in interconnectability due to inflexible and unreliable connection methods, such as soldered wires, clip connectors, and screw-based solutions that can damage the terminal pads or break the internal circuit, restricting the number and length of connections to other strips or power sources.
Innovation Solution
The implementation of two-port screw-in terminal connectors at opposite ends of the LED light strip, permanently attached by soldering pins to conductive pads, allows for secure and flexible temporary or permanent connections using 18-22 AWG wire, enabling multiple connections to both DC power sources and additional LED light strips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldered wires are used to connect LED light strips, then electrical connection is established, but flexibility and interconnectability are limited due to predetermined length and position
Solution Approach 1:
The invention divides the connection system into separate components: a terminal connector attached to the LED strip and separate wire conductors for connection. This segmentation allows the wire length and connection points to be flexible while maintaining a reliable soldered connection at the terminal block, resolving the contradiction between connection reliability and interconnectability flexibility.
Solution Approach 2:
The terminal connector serves as an intermediary component between the LED strip's conductive pads and the wire conductors. It provides a standardized interface that maintains reliable electrical connection while enabling flexible wiring configurations, thus resolving the contradiction between connection stability and adaptability.
2Adaptability or versatility
If clip connectors or clamp devices are used to connect LED light strips, then connection flexibility is improved, but connection reliability deteriorates due to scraping or damaging terminal contact pads
Solution Approach 1:
The invention separates the flexible connection function from the terminal contact interface. The terminal connector with screw terminals provides a protected interface that clips onto the conductive pads without damaging them, while separate wire conductors provide the flexible connection capability, thus resolving the contradiction between flexibility and reliability.
Solution Approach 2:
The terminal connector acts as an intermediary that protects the conductive pads from direct contact with wire conductors or clamps. The screw-terminal design provides reliable electrical connection without scraping or damaging the pads, while enabling flexible wire connections, thus resolving the contradiction between connection flexibility and reliability.
3Strength
If screw or metal pin connectors are used to connect LED light strips, then mechanical connection strength is improved, but harmful effects occur by puncturing the LED light strip and breaking internal circuits
Solution Approach 1:
The invention segments the connection mechanism so that the screw terminals are contained within a protective terminal connector housing that attaches to the conductive pads without puncturing the LED strip. This separation allows strong mechanical connection through screws while preventing damage to the internal PCB circuits, resolving the contradiction between connection strength and harm prevention.
Solution Approach 2:
The terminal connector serves as an intermediary that provides a mechanical interface for screw connections without exposing the internal PCB to puncture risks. The connector attaches to the conductive pads through a design that avoids penetrating the strip, thus providing strong mechanical connection while preventing harm to internal circuits.
4Reliability
If existing connection devices are used, then single-point connection is achieved, but adaptability for multiple connections is lost
Solution Approach 1:
The terminal connector is designed with multiple screw terminals that can accommodate multiple wire conductors, enabling a single connector to provide multiple electrical connections. This multi-functionality maintains reliable connection stability while enabling adaptability for connecting to power sources, multiple LED strips, or other components, thus resolving the contradiction between connection stability and multi-connection capability.
