Trash Hook Head With Integrated Light for Dark Work Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighters often find themselves in dark and smoke-filled environments while using tools like a trash hook, leading to limited vision and increased risk of injuries due to the need to use both hands, necessitating a directed light source that does not require them to let go of the tool.
Innovation Solution
A tool, such as a trash hook, is integrated with a light at its end to illuminate the path and working area, allowing firefighters to see more efficiently and safely without having to release the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a passive chest mounted light is used, then the firefighter's torso is illuminated, but the working area and path remain dark and invisible
Solution Approach 1:
The patent combines the lighting function with the trash hook tool by integrating a light source into the tool's handle or shaft. This merging allows the light to be positioned close to the working area while maintaining tool functionality, solving the contradiction between illuminating the work area and maintaining ease of operation with a two-handed tool.
Solution Approach 2:
The patent introduces an intermediary lighting system that is attached to the tool itself rather than mounted on the firefighter's chest. This intermediary light source acts as a mediator between the firefighter and the dark environment, providing directed illumination of the working area without requiring the firefighter to release the tool or rely on indirect chest-mounted lighting.
2Productivity
If both hands are used to operate the trash hook, then the tool can be effectively used, but the firefighter loses visual awareness of the surroundings
Solution Approach 1:
The patent merges the lighting function with the trash hook tool by integrating a light source into the tool's handle or shaft. This combination allows continuous illumination of the working area and path while maintaining two-handed operation, thus preserving productivity without losing visual information about the environment.
Solution Approach 2:
The patent transitions from a chest-mounted light source (positioned on the firefighter's body) to a tool-integrated light source (positioned at the end of the tool shaft). This dimensional change in light source positioning directs illumination toward the working area and path ahead, providing visual information in the critical forward direction while allowing two-handed tool operation.
3Illumination intensity
If a directed light source is integrated into the tool, then the working area is illuminated, but the tool structure becomes more complex
Solution Approach 1:
The patent integrates the light source, power source, and control components into the existing tool structure, merging multiple functions into a single unified device. This approach provides directed illumination of the working area while minimizing the increase in overall device complexity by utilizing the tool's existing structural elements.
Solution Approach 2:
The patent creates a multi-functional tool that combines the traditional trash hook functionality with integrated lighting, power management, and potentially wireless communication capabilities. This universal design allows the tool to perform its primary function while simultaneously providing illumination and other supportive functions, justifying the increased complexity through enhanced versatility.

AI summary
A tool apparatus for use in and selective illumination of a working area, the apparatus having a head defining a working end of the apparatus, the head having a head body and at least one leg extending distally from the head body and configured for functional use, the head body having a distally-opening head bore, a handle, a shaft interconnecting the head at a distal end of the shaft and the handle at an opposite proximal end of the shaft, and a light operably installed in the head so as to be coaxial with the shaft and to selectively illuminate the working area beyond the head, the light comprising a housing positioned within the head bore and a light source projecting distally from the housing.
