Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current two-wire two-way LED lamp strings are insufficient in meeting the increasing demand for more complex lighting effects and flexible lamp spacing, as they require a complex five-wire four-way structure that is costly and inflexible in terms of lamp distance.
Innovation Solution
A three-wire four-way LED lamp string configuration where first, second, and third wires connect adjacent LED lamps in a specific pattern, allowing for adjustable wire lengths to simplify the structure and enable controllable lamp spacing, reducing costs and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a five-wire four-way structure is used to achieve four-way lighting effects, then the lighting effect complexity is improved, but the device complexity and cost increase
Solution Approach 1:
The patent merges the five-wire structure into a three-wire structure by combining wire functions. Specifically, the first wire connects to anodes of first and third LED lamps, the second wire connects to cathodes of first and third LED lamps, and the third wire connects to anodes of second and fourth LED lamps, eliminating the need for separate fifth wire while achieving four-way lighting effects.
Solution Approach 2:
Each wire in the three-wire structure serves multiple functions. The first wire serves as both anode connection for first LED lamp and anode connection for third LED lamp. The second wire serves as cathode connection for both first and third LED lamps. This multi-functionality reduces the total wire count while maintaining four-way lighting capability.
2Extent of automation
If SMD LEDs are assembled with fixed-distance stripped conductive parts on continuous wire, then the manufacturing automation is improved, but the adaptability to different lamp distances is worsened
Solution Approach 1:
The patent makes the wire structure dynamic and adjustable by allowing wire lengths to be customized according to different lamp distances. The first, second, and third wires can have different lengths selected based on the specific application requirements, enabling the system to adapt to various lamp spacing configurations while maintaining automated assembly capability through standardized connection interfaces.
Solution Approach 2:
The continuous wire is segmented into separate first, second, and third wires with independently selectable lengths. This segmentation allows each wire to be optimized for specific lamp distances, providing flexibility in lamp spacing while maintaining standardized connection points for automated assembly.
