Solution Overview
Problem
Existing lighting systems for aerial work platforms, such as lift buckets, lack enhanced performance, ergonomics, and flexibility, necessitating improved designs that provide better illumination and secure attachment options.
Innovation Solution
A battery-powered lighting device with a main housing, securing member, and adjustable main light, featuring a battery mount, pivot mechanisms, and a releasable ratchet mechanism for secure attachment to lift buckets, allowing the light to be positioned optimally and easily adjusted between forward and sideward facing positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lighting device is fixed in a single position, then the attachment structure is simple, but the illumination flexibility and area coverage are limited
Solution Approach 1:
The lighting device incorporates a pivot mechanism that allows the light source to rotate between forward and sideward facing positions. This dynamic adjustment capability enables the device to adapt to different illumination requirements while maintaining a relatively simple attachment structure that secures the device to the aerial work platform.
2Area of stationary object
If the light is positioned in multiple adjustable positions, then the area coverage is improved, but the device complexity increases
Solution Approach 1:
The lighting device is divided into separable functional components: a secure attachment mechanism that fixes the device to the platform, and a pivot mechanism that independently adjusts the light orientation. This segmentation allows the area coverage to be enhanced through positional adjustment without significantly increasing the overall device complexity, as each component performs a specific function.
3Reliability
If the lighting device uses a secure attachment mechanism with ratchet, then the reliability of attachment is improved, but the ease of operation for adjustment is reduced
Solution Approach 1:
The device employs a ratchet mechanism that provides secure, reliable attachment to the aerial work platform while incorporating a pivot joint that allows smooth adjustment between forward and sideward light positions. The ratchet ensures the device remains firmly attached during operation, while the pivot mechanism maintains ease of adjustment through its mechanical design that allows controlled movement without compromising attachment security.

AI summary
A battery powered lighting device is configured to be attached to lift bucket having sidewalls and an upper lip extending from uppermost portions of the sidewalls. The lighting device includes a main housing, a securing member, and a main light mounted to the main housing and located to illuminate areas outside of the lift bucket. The main housing includes a first securing surface and an upper housing portion, with the upper housing portion configured to be located above the upper lip of the lift bucket with the first securing surface engaged against a surface of the lift bucket. The main light is mounted to the main housing to move between a lower position wherein the main light is positioned below the upper housing portion and an upper position wherein the main light is positioned above the upper housing portion.
