Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional LED modules are secured to aluminum bar using screws or adhesive tape, then reliable attachment is achieved, but on-site installation becomes difficult and time-consuming
Solution Approach 1:
The LED lightstick is divided into modular segments (LED modules) that can be independently attached and detached from the aluminum bar. Each module has its own attachment mechanism, allowing for easy on-site installation and reconfiguration without requiring complex screw or adhesive applications.
Solution Approach 2:
The patent replaces the conventional screw or adhesive tape attachment system with a snap-fit mechanical engagement system. The LED modules feature integrated attachment mechanisms that snap directly onto the aluminum bar, eliminating the need for tools or adhesives while maintaining reliable attachment.
2Ease of manufacture
If LED lightsticks are manufactured in fixed lengths, then manufacturing simplicity is maintained, but versatility for different lighting applications is severely limited
Solution Approach 1:
The lightstick is designed as a modular system where the aluminum bar and LED modules are separate, interchangeable components. This segmentation allows the same basic module to be used in various configurations and lengths, providing versatility without requiring custom manufacturing for each application.
Solution Approach 2:
The lightstick system transitions from fixed-length manufacturing to adjustable, dynamic configuration. Users can assemble different lengths and arrangements of standard modules on-site, allowing the system to adapt to various lighting requirements while maintaining simple standardized manufacturing processes.
3Stability of the object's composition
If LED modules are fixed in position on lightsticks, then structural stability is achieved, but flexibility for different positioning requirements is lost
Solution Approach 1:
The lightstick system is segmented into discrete, independently positionable modules. Each LED module can be attached at different locations along the aluminum bar, allowing flexible positioning while maintaining stable structural connections through the modular attachment system.
Solution Approach 2:
The system allows change in the positional parameter of LED modules along the aluminum bar. Modules can be installed at various positions to meet different lighting requirements, while the attachment mechanism ensures stable structural connection at each position.

AI summary
An LED module lightstick has an elongated extruded strip with upper and lower slots extending the length of the strip. LED modules are located atop the strip, each of the modules having downwardly extending snap-fit arms which hug the sides of the strip. Threaded position pins extend from each module and into the slot for adjustably connecting the modules to the strip. End terminals are located at the distal ends of the strip. Each end terminal has a columnar support circumscribing an open space into which the distal ends of the strip are inserted. Threaded position pins extend through the columnar supports and into the slots, thereby connecting the end terminals to the strip. In this manner, the length of the light stick is adjustably controlled. An extension member is also available to provide additional lightstick length options.
