Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fastening methods are used for LED light bars and light guide plates, then assembly is simple, but positioning accuracy and structural stability deteriorate
Solution Approach 1:
The patent introduces groove structures as intermediary elements between the LED light bars and light guide plates. These grooves serve as positioning features that guide and constrain the relative positions of components, ensuring accurate alignment without requiring complex external fixtures or multiple fastening points.
Solution Approach 2:
The patent employs elastic rubber strips as flexible fastening elements. These rubber strips can deform to accommodate assembly tolerances while maintaining secure holding force, providing both positioning accuracy and structural stability. The elasticity allows for easy installation while ensuring reliable fixation of the LED components.
2Ease of operation
If LED light bars are loosely mounted, then assembly is easy, but lighting effect and uniformity deteriorate
Solution Approach 1:
The groove structures act as intermediaries that simultaneously provide positioning guidance and secure retention. The grooves are designed with specific dimensions that match the LED light bars, allowing for easy insertion while ensuring precise positioning. This eliminates the need for complex assembly procedures while maintaining consistent lighting uniformity through accurate component placement.
Solution Approach 2:
The elastic rubber strips provide a flexible yet secure mounting solution. They allow for easy assembly by simply inserting the LED light bars into the grooves, where the rubber strips automatically grip the components. This simple assembly process ensures consistent positioning and uniform lighting without requiring complex fastening operations.
3Stability of the object's composition
If rigid fastening is used for light guide plate, then positioning stability is improved, but heat dissipation deteriorates
Solution Approach 1:
The elastic rubber strips provide secure positioning stability through their elastic gripping force, while simultaneously maintaining thermal contact between the LED light bars and the heat dissipation structures. The flexibility of the rubber allows for intimate contact with the LED components, ensuring efficient heat transfer without requiring rigid mechanical fastening that would create thermal barriers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the lighting effect by ensuring uniform light distribution, reducing light leakage, and extending the service life of the LED panel light through improved heat dissipation and structural stability, while also making the assembly and maintenance more efficient.
Implementation Method 1
on the upper side face of the groove, there are elastic rubber strips installed in the lengthwise direction. The edges of the light guide plate stated above plunge into the groove and the both side faces of the light guide plate press against the flange and elastic rubber strips herein respectively.
Implementation Method 2
on the side face opposite to the face where the arc slots are, there are several heat sink strips in the lengthwise direction of the seats. These heat sink strips are parallel to each other and equally spaced. The heat dissipation is very important to LED light fixtures.

AI summary
An LED panel light comprises a cover, LED light bars, two long and strip-shaped seats which are fixed on the side faces of the cover and are used to fasten the LED light bars, and a light guide plate between the two seats with the LED light beads on the LED light bars toward the light guide plate. On the seat, there is a groove designed in the lengthwise direction. The LED light bars are fixed at the bottom face of the groove. On the lower side face of the groove, there is a flange protruding toward the upper side face. On the upper side face of the groove, there are elastic rubber strips installed in the lengthwise direction. The edges of the light guide plate plunge into the groove and the both side faces of the light guide plate press against the flange and the elastic rubber strips, respectively.
