Cantilevered Arm Light Stabilization With Mobile Counterweight Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cantilevered arm lights are prone to falling or toppling forwardly, leftwardly, or rightwardly due to their cantilevered extension, posing risks of instability and potential accidents.
Innovation Solution
A base composed of square metal tubing forming a 'V' configuration with stabilization plates and counter-balancing weights, along with a vertically extending support column and roller casters, provides structural stability and mobility by resisting toppling motions and allowing rolling movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a cantilevered arm is extended to reach further areas, then the lighting coverage area is improved, but the stability of the light assembly deteriorates and it becomes prone to toppling
Solution Approach 1:
The patent applies counter-balancing weights positioned on the base plate to offset the toppling moment created by the extended cantilevered arm. These weights create a restoring torque that counteracts the gravitational force acting on the extended arm, preventing the assembly from toppling forward while maintaining the extended reach for lighting coverage.
Solution Approach 2:
The patent transitions from a two-dimensional stability problem to a three-dimensional solution by adding vertical counter-balancing weights and using a V-shaped base configuration. This dimensional approach allows the system to achieve stability in the horizontal plane while maintaining extended reach, resolving the contradiction between coverage area and stability.
2Stability of the object's composition
If the base is made wider to improve stability, then the resistance to toppling is improved, but the mobility of the assembly deteriorates
Solution Approach 1:
The patent employs caster wheels that allow the base to dynamically adapt to movement requirements. The casters enable easy mobility when needed while the counter-balancing weights and V-shaped base provide passive stability when the assembly is stationary, resolving the contradiction between stability and mobility through dynamic adaptability.
3Stability of the object's composition
If counter-balancing weights are added to prevent toppling, then the stability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the counter-balancing weights with the base structure itself, integrating the stability function into the foundational element of the assembly. This integration reduces overall device complexity by combining multiple functions (support and counter-balancing) into a unified structure rather than adding separate components.
