Solution Overview

Problem

Existing work lights are not efficiently configurable for easy transport and deployment in remote work areas, lacking a compact and self-supporting design that allows for flexible positioning and stable illumination.

Innovation Solution

A stand light with a telescoping body, pivotable light heads, and collapsible legs, enabling a compact storage position for transport and an expandable operating position for stable support, along with a user interface for power management and device charging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the work light is designed to be compact for transport, then portability is improved, but stability and support capability deteriorate

Engineering Contradiction:
Improvestorage volumeVSAvoidstand stability
Core Design Contradiction:
Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The stand light employs dynamic legs that can transition between collapsed and expanded states. The legs are coupled to the collar and configured to collapse against the elongate body in storage position, then expand outward in operating position to provide stable support. This dynamic transformation allows the same structure to fulfill both compact transport and stable support requirements.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the light head is fixed in position, then structural simplicity is improved, but positioning flexibility and illumination coverage deteriorate

Engineering Contradiction:
Improvestructural complexityVSAvoidillumination positioning
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The light head assembly incorporates pivotable joints that enable dynamic adjustment of illumination direction. The light head can pivot relative to the elongate body, allowing operators to direct light toward different work areas. This dynamic positioning capability provides illumination versatility without requiring complex multi-component structures.

Inventive Principle:
Principle #15Dynamics

3Duration of action of stationary object

If the work light remains deployed at job sites, then illumination availability is improved, but transport efficiency and setup time deteriorate

Engineering Contradiction:
Improveillumination durationVSAvoiddeployment time
Core Design Contradiction:
Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The stand light is designed with pre-configured collapsible legs and telescoping elongate body that can be rapidly deployed from compact storage position to extended operating position. The legs are pre-positioned to collapse against the body during transport, and the telescoping mechanism allows quick extension when needed, reducing both setup and teardown time while maintaining prolonged illumination capability at job sites.

Inventive Principle:
Principle #10Preliminary action

AI summary

A stand light includes an elongate body defining a longitudinal axis, a collar coupled to the elongate body for movement along the elongate body between a first position and a second position, and a plurality of legs coupled to the collar, the plurality of legs being collapsed against the elongate body when the collar is in the first position and being expanded apart from the elongate body when the collar is in the second position. The stand light also includes a head assembly coupled to an end of the elongate body. The head assembly includes a hub and a plurality of light heads. The hub is pivotably coupled to the end of the elongate body to pivot about a first pivot axis. Each of the plurality of light heads is pivotably coupled to the hub to pivot about a second pivot axis.
