Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld implements used in low-light conditions often require setting up cumbersome task lighting, which can be time-consuming and inefficient, and existing solutions tend to illuminate larger areas than needed, causing disruption and poor lighting for the user.
Innovation Solution
A handheld implement with a light source mechanically coupled to the handle, positioned to illuminate the area near the implement head, allowing for user-modifiable beam size and position, powered by a solar cell or battery, and attachable via a clip or integral to the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source is added to illuminate the work area, then illumination intensity is improved, but device complexity increases
Solution Approach 1:
The light source is nested within or integrated into the existing handle structure of the handheld implement. The handle serves dual purposes as both the structural component for holding the implement and as the mounting structure for the light source, eliminating the need for separate mounting hardware and reducing overall device complexity.
Solution Approach 2:
The handle of the handheld implement is designed to serve multiple functions: it provides the structural framework for holding the implement, supports the implement head, and simultaneously serves as the mounting structure for the light source. This multi-functionality reduces the need for additional components and simplifies the overall device design.
2Illumination intensity
If a light source is positioned to illuminate the work area, then task lighting effectiveness is improved, but loss of time for setup increases
Solution Approach 1:
The light source is merged with the handheld implement as an integrated unit. The light source, its mounting structure, and power source are combined with the implement handle, allowing the user to have task lighting immediately available without separate setup steps. The lighting function is activated simply by using the implement, eliminating dedicated setup time.
3Illumination intensity
If a light source illuminates a larger area, then general visibility is improved, but object-generated harmful factors increase due to disruption to others
Solution Approach 1:
The light source is positioned and directed to provide localized illumination specifically at the work area near the implement head. The lighting is concentrated where the user needs to see for the task at hand, rather than illuminating a broad area. This localized approach provides sufficient visibility for the user while minimizing light spill and disruption to surrounding areas and other people.
4Adaptability or versatility
If a light source is mechanically coupled to the handle, then adaptability is improved, but device complexity increases
Solution Approach 1:
The mounting structure is designed with universal compatibility to attach to various types of handheld implement handles. The same mounting mechanism can be used across different implement types (shovels, rakes, brooms, etc.), providing adaptability without requiring implement-specific customization. This universal design reduces the complexity that would arise from creating multiple specialized mounting solutions.
