Innovation Solution
The LED hose lamp design incorporates three conducting wires arranged in parallel or intertwisted, with insulation layers removed at intervals to form welding spots for SMD LED attachment, and a soft tube coating for increased strength and reduced voltage decay, allowing for series, parallel, or hybrid connections, and automated production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two conducting wires are used for LED connection, then the structure is simple, but the strength is insufficient and LEDs are easy to fall off when subjected to external force
Solution Approach 1:
The conducting wire system is segmented into three distinct wires: first conducting wire for power supply, second conducting wire for signal transmission, and third conducting wire for mechanical support and grounding. This segmentation allows each wire to perform its specific function optimally, with the third wire specifically dedicated to providing mechanical strength and preventing LED dislodgment.
Solution Approach 2:
The patent transitions from a two-wire planar configuration to a three-wire spatial configuration, adding a mechanical support dimension. The third conducting wire is positioned to provide structural reinforcement, creating a three-dimensional arrangement that enhances mechanical strength while maintaining electrical functionality.
2Illumination intensity
If LEDs are connected in parallel, then the brightness is sufficient, but the voltage attenuation is high and production efficiency is low
Solution Approach 1:
The patent enables dynamic configuration flexibility, allowing the LED string light to be adapted for series, parallel, or hybrid connections depending on the specific application requirements. This dynamic adaptability allows optimization of both brightness and production efficiency based on whether parallel or series connection is more suitable for the given scenario.
Solution Approach 2:
The patent changes the electrical connection parameters by introducing the third conducting wire that enables both series and parallel connection configurations. This parameter change allows the system to switch between different connection modes, optimizing for either brightness (parallel) or production efficiency (series) as needed.
3Productivity
If LEDs are connected in series, then the production efficiency is improved, but the voltage decay rate increases and the length is limited by power supply
Solution Approach 1:
The third conducting wire serves multiple functions simultaneously: it provides mechanical support to prevent LED dislodgment, enables series connection configuration for improved production efficiency, and extends the maximum length of the LED string light by providing an additional current path that reduces voltage decay limitations.
Solution Approach 2:
The patent creates a redundant current path through the third conducting wire, effectively copying the electrical connection function. This allows the system to maintain electrical continuity over longer distances by providing alternative current paths, thereby extending the maximum length of the LED string light.
4Reliability
If two conducting wires are used, then the device complexity is low, but the reliability is insufficient under external force
Solution Approach 1:
The third conducting wire is installed beforehand to provide mechanical support and structural reinforcement to the LED string light. This pre-installed support structure acts as a cushioning element that prevents LED dislodgment when external forces are applied, thereby improving reliability before any failure can occur.
Solution Approach 2:
The patent creates a composite conducting wire system that combines electrical functionality with mechanical strength. The three-wire configuration forms a composite structure where the first two wires provide electrical functions and the third wire provides mechanical support, creating a composite system that is both electrically functional and mechanically reliable.
