Caulk Nozzle Lighting Assembly for Multi-Angle Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing caulking guns lack lighting systems that effectively illuminate the nozzle and surrounding work area from multiple angles, hindering visibility during use, especially in underlit conditions.
Innovation Solution
A caulk gun with a cartridge holder and integrated lighting assembly that emits light forwardly from the front wall, featuring a pair of light sources positioned to illuminate the nozzle and work area from multiple sides, powered by a battery and controlled by a power switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single light source is used to illuminate the nozzle, then the device complexity is reduced, but the illumination coverage and viewing angles are limited
Solution Approach 1:
The lighting assembly is segmented into multiple independent light sources (first light source and second light source) positioned at different locations on the cartridge holder. Each light source illuminates a specific portion of the nozzle, enabling comprehensive illumination coverage without requiring a single complex lighting system.
Solution Approach 2:
The patent transitions from single-point illumination to multi-dimensional illumination by positioning light sources at different spatial locations (front wall and side walls). This creates illumination from multiple angles simultaneously, improving viewing capabilities from various perspectives.
2Illumination intensity
If light sources are positioned to illuminate from multiple sides, then viewing from multiple angles is improved, but light obstruction increases
Solution Approach 1:
Each light source is strategically positioned to illuminate specific portions of the nozzle from different angles. The first light source on the front wall illuminates the front portion, while the second light source on the side wall illuminates the side portion, creating localized illumination zones that minimize mutual obstruction.
Solution Approach 2:
The light sources are positioned asymmetrically at different locations (front wall versus side wall) rather than symmetrically, allowing them to illuminate different portions of the nozzle from optimal angles. This asymmetric positioning reduces the likelihood of light sources blocking each other's illumination paths.
3Illumination intensity
If multiple light sources are integrated into the cartridge holder, then illumination coverage is improved, but the device complexity increases
Solution Approach 1:
The lighting assembly is merged with the cartridge holder structure, with light sources integrated directly into the cartridge holder's walls. This integration combines the illumination function with the existing structural components, avoiding the need for separate mounting brackets or external lighting devices.
Solution Approach 2:
The cartridge holder serves multiple functions: it holds the caulk cartridge, provides structural support, and integrates the lighting system. The front wall and side wall that form part of the cartridge holder structure also serve as mounting surfaces for the light sources, eliminating the need for dedicated lighting mounts.

AI summary
A caulk nozzle lighting system for lighting a nozzle of a caulk cartridge and an adjacent work area includes a caulk gun which has a cartridge holder with a front wall, a back wall, and a perimeter wall. The perimeter wall is coupled to and extends between the front wall and the back wall. The cartridge holder defines a bay for accommodating the caulk cartridge surrounded by the front wall, the back wall, and the perimeter wall. A lighting assembly is mounted to the front wall of the cartridge holder of the caulk gun and is configured to emit light forwardly with respect to the front wall.
