Resilient Light Bulb Holder for Ladder Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light bulb holders are either fragile, inefficient in use, or require manual force for bulb insertion and removal, and often expose long fluorescent bulbs to breakage during installation or replacement, necessitating multiple trips and labor inefficiencies.
Innovation Solution
A light bulb holder with resilient arcuate fingers made from pliable material, securely attachable to a ladder via Velcro or other fasteners, allowing easy insertion and removal of bulbs without manual force, providing protection and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flexible bag holster is used to hold light bulbs, then the device is easy to manufacture and transport, but it provides insufficient protection against breakage
Solution Approach 1:
The holder combines a rigid outer shell made of plastic or metal with a soft inner lining made of foam or rubber. This composite structure provides both structural strength to prevent breakage and cushioning to protect the bulbs, resolving the contradiction between ease of manufacture and reliability.
2Device complexity
If bulbs are loosely held in pockets, then the holder is simple in structure, but the bulbs are exposed to breakage and not separated from one another
Solution Approach 1:
The holder is divided into multiple individual compartments or pockets, each designed to hold a single bulb. This segmentation prevents bulbs from contacting each other and provides individual protection, while the overall structure remains simple and easy to manufacture.
3Device complexity
If only one end of the fluorescent light bulb is supported, then the holder structure is simple, but a large length of the bulb is exposed to breakage
Solution Approach 1:
The holder extends along the length of the fluorescent bulb, providing support in multiple locations rather than just at one end. This dimensional extension ensures the entire bulb is protected during handling, while the structure remains simple through the use of a continuous cradle design.
4Reliability
If manual force is required to insert and remove bulbs, then the holder provides secure retention, but the operation becomes difficult and time-consuming
Solution Approach 1:
The holder incorporates elastic or spring-loaded gripping elements that dynamically adjust to the bulb's presence. When a bulb is inserted, the elastic fingers automatically close to secure it; when removed, they naturally open to facilitate easy insertion of the next bulb, eliminating the need for manual force.
5Ease of operation
If two servicemen are used to change light bulbs, then bulb transfer is facilitated, but labor efficiency decreases and breakage risk increases
Solution Approach 1:
The holder is designed to be self-sufficient, allowing a single serviceman to carry multiple bulbs and perform all replacement operations independently. The holder's design facilitates easy bulb access and installation without requiring assistance, thereby improving labor efficiency and reducing breakage risk from additional handling.
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 holder securely retains bulbs, reducing breakage and labor, enabling efficient single-person bulb replacement with ease of transport and use, while being adaptable to various bulb types and ladder configurations.
Implementation Method 1
resilient fingers may be made from a pliable shape-retaining material
Implementation Method 2
The holder may be permanently affixed or removably attachable to a ladder

AI summary
A light bulb holder including a bulb retaining body for holding a light bulb during installation of the bulb in a light fixture. The bulb retaining body generally includes an attachment member for removably or permanently affixing said retaining body to a ladder and at least one retaining slot unit supported on said attachment member including a base and opposed resilient fingers defining an opening for receiving a light bulb.
