Panel Lamp Housing-Lampshade Joint Without Frame or Glue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional panel lamps require a frame structure that is hidden but redundant, and the bonding firmness of glue is uncertain, leading to structural redundancy and potential instability.
Innovation Solution
A frame-free design where the lamp housing is directly connected to the lampshade through thermally deformed connecting plates, eliminating the need for a traditional frame and ensuring a firm connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a frame structure with glue bonding is used to connect the lampshade to the lamp housing, then the mounting surface appears aesthetic with the frame hidden, but the bonding firmness is uncertain and the structure becomes redundant
Solution Approach 1:
The patent removes the traditional frame structure from the lamp assembly. Instead of using a separate frame that is bonded with glue, the lamp housing itself is designed with an integrated connecting plate that directly connects to the lampshade, eliminating the frame and its associated bonding reliability issues while maintaining the aesthetic appearance.
Solution Approach 2:
The connecting plate is integrated directly into the lamp housing structure rather than being a separate component. This merging of the connecting plate with the lamp housing eliminates the need for separate frame structures and glue bonding, creating a more reliable and simplified connection system.
2Shape
If a frame structure with glue bonding is used to connect the lampshade to the lamp housing, then the frame can be hidden on the mounting surface, but the structure becomes redundant and complex
Solution Approach 1:
The patent extracts and removes the redundant frame structure from the design. The connecting plate is integrated directly into the lamp housing, eliminating the need for a separate frame component while maintaining the aesthetic appearance of a hidden structure.
Solution Approach 2:
The frame function is merged into the lamp housing itself through the integrated connecting plate. This consolidation eliminates structural redundancy by combining multiple components (frame, housing, connecting elements) into a single integrated structure.
3Shape
If glue bonding is used to connect the diffuser plate to the frame, then the frame structure can be hidden, but the bonding firmness requires verification and the connection may be unstable
Solution Approach 1:
The patent replaces the chemical bonding method (glue) with a mechanical connection system. The integrated connecting plate provides a physical, mechanical connection between the lamp housing and lampshade, eliminating the need for glue bonding and its associated strength verification issues.
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
The solution simplifies the structure by eliminating the frame and ensures a secure, stable connection between the lamp housing and lampshade without relying on glue, enhancing structural integrity.
Implementation Method 1
the lamp housing is a metal housing, the lampshade is a plastic plate, and the fourth connecting plate is formed from the lampshade by thermal deformation

AI summary
A panel lamp comprise a lamp housing, a light emitting assembly disposed inside the lamp housing, a lampshade having a top surface disposed under the lamp housing, the lamp housing comprises a roof and a circle of peripheral wall extending downward from an edge of the roof, the lamp housing has a first connecting plate extending outward from an edge of the peripheral wall, the lampshade has a fourth connecting plate extending inward from an edge of the lampshade, and, an accommodating space is defined between the fourth connecting plate and the top surface of the lampshade for the first connecting plate of the lamp housing positioned and located within. The panel lamp of the present invention does not require the additional frame, The lamp housing and the lampshade are directly limited and connected, which simplifies the structure of the panel lamp. In addition, the lampshade is bent and deformed to be clamped with the lamp housing, so the both are connected firmly.
