Solution Overview

Problem

Existing flat lamps with light guide plates are difficult to mount on roofs due to their large light emitting surface and small body frame, making them cumbersome and aesthetically challenging to integrate with the roof design.

Innovation Solution

A flat lamp design featuring a lamp body with an L-shaped corner connector, an LED plate, a U-shaped groove, and a fixing assembly with parallel support plate members and a cover plate, allowing for easy snap-fitting and screwing onto the roof, ensuring a secure and aesthetically pleasing installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the light guide plate has a large light emitting surface and small body frame, then the luminous area is increased, but the mounting difficulty increases

Engineering Contradiction:
Improveluminous areaVSAvoidmounting ease
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The lamp body is divided into multiple components: corner connectors, frame, light guide plate, upper support plate, and fixing assembly. This segmentation allows each part to be optimized independently - the light guide plate maintains large luminous area while the fixing assembly provides easy mounting capability through separate attachment mechanisms

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The components are nested within each other - the LED plate is caught by U-shaped grooves in the frame, the upper support plate snap-fits onto the lamp body opening end, and the fixing assembly is arranged over the upper support plate. This nesting allows compact integration while maintaining ease of assembly through sequential installation

Inventive Principle:
Principle #7Nested doll (Nesting)

2Shape

If the lamp body frame is made small to achieve thin structure, then the aesthetic integration with roof is improved, but the structural strength decreases

Engineering Contradiction:
Improvethin structureVSAvoidstructural strength
Core Design Contradiction:
ShapeVSStrength

Solution Approach 1:

The lamp body combines multiple materials with complementary properties: the frame provides structural support, the light guide plate provides aesthetic thin profile with large luminous area, and the fixing assembly provides additional structural reinforcement. This composite structure achieves both thin aesthetic appearance and sufficient structural strength

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The corner connectors use L-shaped configurations that provide structural strength at corners while maintaining thin overall profile. The curved or angled connections distribute stresses more effectively than straight rigid connections, enabling thin structure with adequate strength

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Illumination intensity

If the lamp body is designed with large light emitting surface, then the illumination effectiveness is improved, but the mounting precision requirement increases

Engineering Contradiction:
Improveillumination effectivenessVSAvoidmounting precision
Core Design Contradiction:
Illumination intensityVSManufacturing precision

Solution Approach 1:

The U-shaped grooves in the frame automatically catch and position the LED plate, while the upper support plate snap-fits onto the lamp body opening end. These self-positioning features guide components into correct positions during assembly, reducing mounting precision requirements despite the large light emitting surface that requires accurate positioning

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The frame and support plate have locally optimized features - U-shaped grooves at specific locations to catch LED plates, snap-fit structures at the opening end, and reinforcement areas in the fixing assembly. These localized precision features ensure proper positioning of critical components while allowing tolerances in non-critical areas

Inventive Principle:
Principle #3Local quality

AI summary

A flat lamp with a light guide plate comprises a lamp body, an LED plate arranged on a side wall of the lamp body, an upper support plate snap-fitted and connected to an opening end of the lamp body, and a fixing assembly arranged over a surface of the upper support plate and connected with the upper support plate. A method for mounting the flat lamp comprises steps of screwing screws into arc grooves of the cover plate of the fixing assembly and into screw holes provided at ends of the support plate members and fixing the fixing assembly on a roof; and moving the support plate members (41) to allow them to slide into the V-shaped bent portions of the connecting components and then continue sliding until being restrained by the bent plate at an end.
