Omni-Directional Work Light Protective Member for Tip-Over Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing omni-directional work lights are fragile and prone to damage when placed on uneven surfaces, requiring complex anti-tipping structures to prevent the light head assembly from being tipped over.
Innovation Solution
An omni-directional work light with a protective member below the light socket, designed to touch the ground before the transparent cover, featuring a radial projection larger than the cover, and a collapsible leg system for stability and adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-volume light head assembly is used to achieve 360-degree illumination coverage, then the illumination coverage is improved, but the light head assembly becomes more fragile and prone to tipping over when placed on uneven surfaces
Solution Approach 1:
A protective member is introduced as an intermediary element between the light head assembly and the ground. This protective member extends below the light socket and has a projection on the radial plane that is larger than the transparent cover projection, creating a buffer zone that prevents direct contact between the fragile light head assembly and the ground during tipping events.
Solution Approach 2:
The protective member is positioned in advance below the light socket to provide cushioning protection before any impact occurs. By having this protective structure already in place with adequate radial extension, the design anticipates potential tipping scenarios and prevents damage before it can occur to the light head assembly.
2Reliability
If a complex anti-tipping structure is added to protect the light head assembly from damage when tipped over, then the drop resistance is improved, but the device complexity increases
Solution Approach 1:
The protective function is extracted from the main light head assembly structure and implemented as a separate, dedicated protective member. This allows the light head assembly to maintain its illumination function while the protective member independently provides drop resistance, avoiding the need for complex integrated anti-tipping mechanisms.
Solution Approach 2:
Protection is applied locally where it is most needed - below the light socket where the vulnerable light head assembly would contact the ground during a tip. The protective member is strategically positioned and dimensioned to provide focused protection at the critical impact zone rather than requiring comprehensive structural reinforcement throughout the entire device.

AI summary
An omni-directional work light includes an elongated body having a longitudinal axis and a light head assembly connected to a top end of the elongated body. The light head assembly includes a light source with a transparent cover and a light socket where the light socket defines a radial plane perpendicular to the longitudinal axis. A plurality of legs are pivotally connected to the elongated body and movable between a folded position in which the plurality of legs are folded against the elongated body and an unfolded position in which a respective distal end of the plurality of legs is unfolded away from the elongated body. A protective member is disposed below the light socket where a projection of the transparent cover on the radial plane is within a projection range of the protective member on the radial plane.
