Harp Assembly for Loop Light Shade Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lamp shades frequently become disoriented due to human interaction, seismic activity, wind forces, and other subtle movements, leading to frequent adjustments, which is inconvenient, especially for inaccessible installations like chandeliers.
Innovation Solution
A kit-based assembly that converts loop-mounted lamp shades into a more stable mounting configuration using a harp assembly with distal portions and a securement piece to prevent disorientation, featuring a harp assembly with adjustable sections and a headpiece that compresses the loop ring for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If loop-type shade mounts are used to attach lamp shades to light bulbs, then the installation is simple and economical, but the shade becomes prone to disorientation and misshaping
Solution Approach 1:
The patent implements a nested structure where the harp assembly is positioned inside the lampshade, with the distal portions extending through the top opening. The securement piece fits over these distal portions, creating a nested configuration that secures the shade to the bulb while maintaining ease of installation and improving stability against disorientation.
2Shape
If chandeliers are installed in high locations for aesthetic purposes, then the visual appeal is improved, but the accessibility for shade adjustment becomes difficult
Solution Approach 1:
The harp assembly with securement piece creates a self-securing mechanism that maintains shade orientation automatically. The distal portions extend through the shade and the securement piece locks them in place, allowing the shade to self-correct and maintain proper orientation without requiring manual adjustment from below, thus solving the accessibility problem for high-mounted chandeliers.

AI summary
An adaptor or an original lamp. The adaptor is used with a lamp having a light bulb to better mount a loop-type lamp shade thereon. The adaptor has a harp assembly with harp sections that extend from a mounting ring or collar that fits about the head of the lamp. The collar can be eliminated when the apparatus is built in to the lamp head during manufacture. The adapter allows support of the lamp shade by both the loops and using a harp to thus reduce tilting or other disorientation of the lamp shade.
