Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work lights lack a compact and efficient design that allows for easy storage and deployment, with telescoping mechanisms that are cumbersome or require manual actuators for extension and retraction, and do not provide a stable self-supporting structure for various work environments.
Innovation Solution
A telescoping stand light with a body comprising a main center shaft and extendable poles, a sleeve for leg movement, and a head assembly, featuring a detent mechanism for secure extension, a light shroud for compact storage, and actuators for easy collapsing and extending, allowing for stable self-support on surfaces and convenient handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If telescoping mechanisms are used to reduce storage space, then the light becomes more compact and easier to store, but the extension and retraction mechanisms become cumbersome and require manual actuators
Solution Approach 1:
The telescoping poles automatically extend and retract using spring-loaded mechanisms and cam-locked positioning systems. The legs self-deploy when the poles are extended, eliminating the need for manual actuators or complex locking mechanisms. This self-service approach resolves the contradiction by making the telescoping mechanism both compact and easy to operate.
Solution Approach 2:
Spring-loaded mechanisms are pre-loaded to automatically propel the telescoping poles outward when released. The cam-locked positioning systems are pre-configured to engage at specific extension positions, providing automatic stabilization without requiring manual intervention during operation.
2Stability of the object's composition
If the light is designed to be self-supporting on surfaces, then it provides stable support for various work environments, but it requires a complex leg deployment mechanism
Solution Approach 1:
The support structure is divided into multiple segmented legs that can independently deploy and adjust. Each leg is a separate component with its own positioning mechanism, allowing the system to adapt to various surface conditions while keeping each individual leg mechanism relatively simple.
Solution Approach 2:
The legs are nested within the pole structure when collapsed, and automatically deploy outward as the poles extend. This nesting arrangement eliminates the need for separate storage compartments or complex folding mechanisms, reducing overall device complexity while maintaining self-support capability.
3Reliability
If detent mechanisms are used to secure the extension pole, then the pole retention becomes secure and reliable, but the mechanism adds complexity to the device
Solution Approach 1:
The detent mechanism uses cam-locked positioning systems that leverage mechanical advantage through cam surfaces rather than traditional multi-component detent systems. This substitution reduces the number of parts while maintaining secure retention through the self-locking nature of the cam mechanism.
Solution Approach 2:
The detent function is extracted as a separate cam-locked mechanism that operates independently from the main telescoping structure. This modular approach allows the retention function to be implemented with minimal components while maintaining reliability.

AI summary
A stand light (10) includes a telescoping body (14) having a main center shaft (34), an extension pole (30) extendable out of the main center shaft (34), and a sleeve (50) movably supported on the main center shaft (34). A head assembly (26) is supported by the extension pole (30) and includes a light source (112). A plurality of legs (22) is pivotally coupled to the body (14) and is movable with the sleeve (50) from a collapsed position to an extended position, in which distal ends of the plurality of legs (22) are moved away from the body (14). The stand light (10) further comprises a light shroud (46) coupled to an end of the main center shaft (34), the light shroud (46) including notches (122) formed on inner surfaces of sidewalls (126) of the light shroud (46), the notches (122) receiving portions of a support arm (102) when the head assembly (26) is in a lowest resting position.
