Flexible Lightbulb Gripper for Obstructed Upward-Facing Sockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for replacing upward-facing lightbulbs are inefficient and hazardous due to the need for ladders and the complexity of accessing partially obstructed sockets in fixtures like chandeliers, which can lead to accidents and difficulty in handling various bulb types and sizes.
Innovation Solution
A device comprising a gripping element with flexible tactile members, a weight, and a flexible rotary shaft connected to an extension pole, allowing for safe and efficient installation and removal of B-, C-, and CA-shaped lightbulbs with candelabra or intermediate bases from upward-facing, partially obstructed sockets by providing a secure grip and rotational mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ladders are used to reach upward-facing lightbulbs, then accessibility to high ceilings is improved, but safety deteriorates due to risk of falling
Solution Approach 1:
The patent introduces an extension rod as an intermediary tool that transmits rotational force from the user's hand to the lightbulb base. This mediator allows the user to operate the bulb without direct contact, eliminating the need for ladders and associated safety risks while maintaining full control over the replacement operation
Solution Approach 2:
The patent replaces the mechanical ladder system with a lightweight extension rod mechanism that uses leverage and rotational mechanics. Instead of climbing to reach the bulb, the user applies torque through the extension rod, substituting a safe mechanical advantage system for the dangerous climbing approach
2Ease of operation
If extension rods with grasping calipers are used, then removal of lightbulbs from high ceilings is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the essential function needed from complex extension rod designs - the rotational torque transmission. By removing unnecessary grasping calipers and other complicated mechanisms, the invention retains only the critical extension rod component that delivers rotational force, simplifying the device while maintaining effectiveness
Solution Approach 2:
Instead of using complex calipers to grasp the bulb, the patent inverts the approach by having the user grasp the extension rod handle and transmit rotation directly to the bulb base. This reversal simplifies the mechanism by eliminating the need for automated grasping components
3Shape
If decorative elements of chandelier are present, then aesthetic appearance is improved, but accessibility to lightbulbs deteriorates due to obstruction
Solution Approach 1:
The patent exploits the vertical dimension by inserting the extension rod from above into the bulb base. This top-down approach bypasses the horizontal obstruction created by decorative chandelier elements, allowing access to sockets that are otherwise blocked from side approaches while preserving the fixture's aesthetic integrity

AI summary
The present invention is a device for installing and removing partially obstructed, upward-facing lightbulbs. It is comprised of a gripping element, a weight, a flexible rotary shaft having two ends, and an extension pole having two ends. The gripping element, itself, is comprised of a hollow, three-dimensional gripping element body having an inner and outer surface and a plurality of flexible, tactile members. The hollow, three-dimensional gripping element body is open at one end and closed at the other. At the open end, the plurality of flexible, tactile members are arranged about a peripheral rim at the opening. When the device is placed over a lightbulb, the flexible, tactile members capture the lightbulb. Rotating the extension pole will cause the lightbulb to rotate.
