Wheeled Stand With Locking Casters For Heavy Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheeled support stands for heavy equipment, such as automotive lifting equipment, face challenges in providing a stable and durable mobile base that can support heavy loads without tipping, while also allowing for easy mobility and unobstructed access to operating components.
Innovation Solution
A wheeled equipment stand design featuring mirror-image legs with a rectangular tray and spring-biased cover plate, where the tray is securely attached to the legs with a non-perpendicular angle, and equipped with a wheel assembly and spring-biased cover plate to prevent debris accumulation, enhancing stability and mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the stand uses a wide base and heavy construction to support heavy loads without tipping, then stability and load-bearing capacity are improved, but mobility and ease of movement deteriorate
Solution Approach 1:
The stand employs four caster wheels that can be locked when stationary to provide stability during operation, and unlocked when movement is needed. This dynamic switching between locked and unlocked states allows the stand to achieve both stability and mobility as needed.
Solution Approach 2:
The stand changes its stability parameter by locking or unlocking the caster wheels. When locked, the stand achieves high stability for supporting heavy loads; when unlocked, it becomes mobile for repositioning. This parameter change resolves the contradiction between stability and mobility.
2Strength
If the stand uses a wide base and heavy construction to support heavy loads without tipping, then load-bearing capacity is improved, but device portability deteriorates
Solution Approach 1:
The caster wheels with locking mechanism allow the stand to transition between a portable state (wheels unlocked) and a stable load-bearing state (wheels locked). This dynamic capability enables the stand to be moved when needed while maintaining high load-bearing capacity during operation.
3Ease of operation
If the stand uses a compact design to improve mobility, then ease of movement is improved, but stability and load-bearing capacity deteriorate
Solution Approach 1:
The locking mechanism on the caster wheels enables the stand to achieve stability when needed by locking the wheels in place, despite having a compact design with wheels for mobility. The dynamic locking feature allows the stand to switch between mobile and stable configurations.
4Ease of operation
If the stand uses a compact design to improve mobility, then portability is improved, but load-bearing capacity deteriorates
Solution Approach 1:
The locking caster wheels allow the stand to maintain high load-bearing capacity when locked during operation, while remaining portable when unlocked for movement. This dynamic mechanism resolves the contradiction between portability and load-bearing capacity.
