Foldable Translucent Lampshade Blank for Low-Error Flat-Pack Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lampshades require complex assembly by end users, are prone to errors, and occupy large transport volumes, while delivered as finished products they risk damage during transport.
Innovation Solution
A foldable lampshade blank made of translucent material, comprising interconnected quadrilaterals with fold lines, allowing assembly from two identical or nearly identical pieces, reducing assembly errors and transport volume, and enabling accentuated lighting with partial openness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lampshades are delivered as finished hollow boxes, then assembly is simplified for end users, but transport volume increases and damage risk during transport increases
Solution Approach 1:
The lampshade is divided into multiple flat panels (first panel, second panel, third panel, fourth panel) that can be transported separately and assembled later. These panels are connected through fold lines and adhesive tabs, allowing them to be compact for transport but forming a complete hollow box structure when assembled, thus reducing transport volume while maintaining assembly simplicity.
2Volume of stationary object
If lampshades are delivered as pre-cut pieces requiring assembly, then transport volume is reduced, but assembly becomes time-consuming and error-prone
Solution Approach 1:
The lampshade panels are pre-cut from the translucent material with all necessary fold lines, adhesive tabs, and opening positions already prepared. The panels are designed with complementary adhesive tabs that align precisely, so that when end users assemble the lampshade, they simply need to fold along the marked lines and attach the panels using the pre-positioned adhesive tabs, making the assembly process quick and error-free.
3Illumination intensity
If lampshades are completely closed, then homogeneous light is produced, but lighting accentuation is reduced
Solution Approach 1:
The lampshade design incorporates different types of openings in specific locations: a first opening in the first panel and a second opening in the second panel. These strategic openings allow selective light transmission, creating zones of direct light and diffused light within the same lampshade. This local variation in openness enables both homogeneous light production through the closed portions and lighting accentuation through the open portions, achieving both lighting effects simultaneously.

AI summary
The invention relates to a blank (10) for a lampshade (20) made of a foldable, translucent material and to a lighting system (30) with such lampshades. The blank comprises a first quadrilateral (11), a second quadrilateral (12) connected to the first quadrilateral (11) via a first fold line (21), a third quadrilateral (13) connected to the second quadrilateral (12) via a second fold line (22), a fourth quadrilateral (14) connected to the third quadrilateral (13) via a third fold line (23), and a fifth quadrilateral (15) connected to the fourth quadrilateral (14) via a fourth fold line (24). The first quadrilateral (11) is mirror-symmetrical to the second quadrilateral (12) along the first fold line (21), and the fourth quadrilateral (14) is mirror-symmetrical to the fifth quadrilateral (15) along the fourth fold line (24). The second fold line (22) runs at an angle between 45° and 90° to the fourth fold line (24).
