Lampshade Snap-Fit Assembly for Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art lampshades require high manual assembly, leading to inconsistent results and increased transportation costs due to large packaging volumes and susceptibility to deformation during shipping.
Innovation Solution
A lampshade design featuring elastically snap-fitted ribs and grooves between the lampshade cloth and ring covers, allowing for easy assembly, reduced packaging volume, and enhanced stability during transport by winding or laying the cloth flat, along with detachable sub-rods and a support rod for improved structural integrity and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the lampshade cloth and ring covers are assembled together in advance, then the structural stability is improved, but the packaging volume increases and transportation cost increases
Solution Approach 1:
The lampshade is divided into separate components (lampshade cloth and ring covers) that are packaged separately and assembled later. The lampshade cloth and ring covers are kept as independent parts during transportation, allowing for compact packaging while maintaining structural integrity when assembled.
Solution Approach 2:
The rib and groove structures are pre-formed on the lampshade cloth and ring covers respectively during manufacturing, enabling easy snap-fit assembly later without requiring complex assembly processes. This preliminary preparation allows for both compact packaging and stable final structure.
2Manufacturing precision
If the lampshade cloth is stuck to the ring cover surface, then the assembly consistency is improved, but the manual assembly requirement increases and production efficiency decreases
Solution Approach 1:
The elastic rib automatically engages with the groove through snap-fit action without requiring manual alignment or adhesive application. The structure itself performs the assembly function, eliminating the need for skilled manual labor and ensuring consistent results through the mechanical design rather than human skill.
Solution Approach 2:
The traditional adhesive bonding method is replaced with a mechanical snap-fit connection system using elastic ribs and grooves. This mechanical system provides both assembly consistency and production efficiency by eliminating manual adhesive application and drying time while ensuring precise alignment through the guiding groove structure.
3Stability of the object's composition
If the lampshade is packaged after assembly, then the structural integrity is maintained, but the transportation cost increases due to large volume
Solution Approach 1:
The lampshade is segmented into separate components that can be packaged in a compact state during transportation. The lampshade cloth is rolled or folded separately from the ring covers, dramatically reducing the packaging volume and transportation cost while maintaining the ability to assemble into an intact structure at the destination.
Solution Approach 2:
The physical state of the lampshade cloth is changed from an expanded three-dimensional form to a compact rolled or folded state during packaging. This parameter change in the cloth's configuration allows for space-efficient transportation while the elastic rib-groove mechanism ensures the structure can be easily restored to its intact form after assembly.
4Loss of energy
If the lampshade cloth is packaged in a compact state, then the transportation cost is reduced, but the susceptibility to bending deformation during transport increases
Solution Approach 1:
The lampshade cloth is packaged with protective materials or in a manner that cushions it against bending and deformation during transportation. The compact packaging method includes protective elements that prevent harmful deformation while maintaining space efficiency, addressing both transportation cost and damage prevention needs.
Solution Approach 2:
Protective intermediary materials or structures are introduced between the lampshade cloth and the packaging environment to prevent bending deformation. These intermediaries absorb the mechanical stresses during transportation while allowing the cloth to be packaged in a compact state, thus reducing transportation cost without increasing susceptibility to damage.

Function Achieved in This Case
Simplifies assembly, ensures consistency, reduces transportation and production costs, and minimizes rejection rates by allowing separate packaging of components, while maintaining product aesthetics and structural stability.
Implementation Method 1
A rib and a groove for connecting and fixing the lampshade cloth and the ring cover are disposed between the outer circumferential wall of the ring cover and the mounting surface of the lampshade respectively. The rib and the groove are elastically snap-fitted.

AI summary
The invention provides a lampshade, which solves the problem that the prior art lampshade adopts an overall package and has high transportation cost and is easy to be damaged. A lampshade includes at least two ring covers arranged one above the other and a lampshade cloth surrounding an outer circumferential wall of each of the ring covers to form a closed cover body, the lampshade cloth comprising a mounting surface and a decorative surface, which are oppositely disposed. A rib and a groove for connecting and fixing the lampshade cloth and the ring cover are disposed between the outer circumferential wall of the ring cover and the mounting surface of the lampshade respectively; the rib and the groove are elastically snap-fitted; and the lampshade cloth is elongated and both ends of it are detachably connected with each other.
