Portable Workbench Foldable Frame Rigid Upper Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable workbenches lack a balance between being easily transportable and robust, with most being either too bulky for after-sales service and maintenance work or insufficiently robust to support heavy loads, and they often lack secure storage solutions for tools and equipment.
Innovation Solution
A portable workbench with a foldable frame and a main panel that features a rigid upper framework capable of supporting heavy loads, combined with steerable wheels and an anti-burglary system, allowing for easy transport and secure storage while maintaining robustness and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the workbench is designed to be portable and foldable, then ease of transport is improved, but robustness and load-bearing capacity deteriorate
Solution Approach 1:
The workbench is divided into separable components: a folding frame and a removable main panel. The frame can be folded for compact transport, while the panel can be detached to form a stable working surface when needed, resolving the contradiction between portability and structural integrity.
Solution Approach 2:
The frame employs a dynamic folding mechanism with pivot axes that allow the structure to transition between compact folded state and expanded stable state. This dynamic design enables the workbench to adapt its form factor based on whether it needs to be transported or used, maintaining both portability and robustness at different times.
2Strength
If the workbench structure is made robust to support heavy loads, then load-bearing capacity is improved, but ease of transport deteriorates
Solution Approach 1:
The main panel is designed as a removable component that can be detached from the frame. This allows the heavy load-bearing panel to be left at the worksite while the lighter frame is folded and transported, separating the transport function from the load-bearing function.
Solution Approach 2:
The frame structure includes reinforcing elements and rigid upper frames that provide sufficient strength support when the panel is attached, but these reinforcements do not significantly increase the weight or bulk when the panel is removed for transport, allowing partial application of robustness only when needed.
3Reliability
If the workbench includes secure storage solutions for tools, then security is improved, but device complexity deteriorates
Solution Approach 1:
The storage function is merged with the existing frame structure by integrating lockable compartments or attachment points into the frame design, rather than adding separate independent storage systems. This combines security functionality with the structural elements already present, minimizing additional complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The workbench provides a robust and portable solution that can support heavy loads, facilitate easy movement, and secure storage, making it suitable for various environments and applications, including on-site maintenance and administrative tasks.
Implementation Method 1
said main panel further comprising pivot axes connecting the inner ends of each of said first and second sub-elements, said axes being arranged so that said inner ends are joined in the mounted position of the workbench and are able to pivot upwards for folding the panel for dismantling the workbench
Implementation Method 2
The rigid upper frame is understood as being able to resist a mass placed on the work surface and exerting a force in the direction of gravity
Implementation Method 3
The contact between the inner ends of the first and second front and rear sub-elements of the frame locks the panel in place, preventing it from pivoting downwards when a significant load rests on the work surface
