Pivotable Portable Light Charger with Latch Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable lights used by firefighters and first responders often lack the flexibility to be positioned effectively in hazardous environments and require precise placement for charging, which can be difficult with protective gear, and existing solutions compromise between positionability and durability.
Innovation Solution
A portable light with a pivotable head that can be angled over a wide range and a charger that accepts the light at various angles, featuring coaxial cylindrical projections and receptacles with detents for secure positioning, and latch arms for easy insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light source is made pivotable to improve positionability, then the light can be positioned at desired angles, but the robustness and durability are reduced
Solution Approach 1:
The light head is made pivotable relative to the light body through a hinge mechanism, allowing the light to be dynamically adjusted to various angles while maintaining structural integrity. The hinge allows controlled movement while keeping the connection robust.
Solution Approach 2:
The portable light is divided into separate segments - a light body and a light head - that can move relative to each other. This segmentation allows the light head to be positioned independently while the overall structure remains durable.
2Manufacturing precision
If the charger requires precise placement for charging, then charging contacts align properly, but it becomes difficult to operate with protective gear
Solution Approach 1:
The charger is designed with a universal receptacle that accepts the light body at multiple angles and orientations. The rechargeable battery and charging contacts are positioned within the light body such that proper electrical connection is achieved regardless of the insertion angle, making the charger easy to operate with protective gear while maintaining precise contact alignment.
3Productivity
If the light is designed for quick removal and insertion, then readiness is improved, but secure retention during charging may be compromised
Solution Approach 1:
The charger incorporates latch arms that automatically engage with the light body when inserted, providing secure retention without requiring manual operation. The latch arms can be easily released with a simple action, enabling quick removal while maintaining secure charging connection.
