Foldable Workbench Telescopic Handle Leg Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional workbenches lack efficient mechanisms for easy deployment, storage, and transportation due to rigid leg structures, which limit their portability and space-saving capabilities.
Innovation Solution
A foldable workbench design with telescopic and moveable handle mechanisms that translate handle movements into leg movements, allowing for efficient folding and unfolding, and a locking system for various positions, including full-folded and full-unfolded states, along with slots and holes for tool attachment and measurement markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid leg structures are used in conventional workbenches, then structural stability is improved, but portability and space-saving capabilities deteriorate
Solution Approach 1:
The workbench legs are designed to transition between fixed stable positions and movable folded positions. The linkage mechanism allows the legs to dynamically change their configuration from extended stable support to retracted compact storage, resolving the contradiction between stability and portability.
Solution Approach 2:
The leg structure is divided into multiple segments connected by linkages, allowing independent movement and folding. This segmentation enables the leg to maintain stability when extended while allowing compact folding for portability, addressing both contradictory requirements.
2Stability of the object's composition
If rigid leg structures are used in conventional workbenches, then structural stability is improved, but storage efficiency deteriorates
Solution Approach 1:
The foldable leg mechanism allows the leg components to nest within the workbench frame when folded. The linkage system enables the leg to collapse into a compact configuration that fits within the overall workbench footprint, reducing storage volume while maintaining structural integrity when deployed.
3Stability of the object's composition
If rigid leg structures are used in conventional workbenches, then structural stability is improved, but ease of deployment deteriorates
Solution Approach 1:
The linkage mechanism is designed to automatically lock the leg into stable positions during deployment. As the leg is extended or retracted, the mechanical linkage self-locks at predetermined positions, providing structural stability without requiring manual adjustment or complex fastening operations.

AI summary
A transportable workbench is disclosed the legs of which are easily manipulated and are folded under its top part. With the same ease the legs may be unfolded and erected to create a work-table for working in construction sites and in temporary work places. Each workbench has a telescopic moveable handle and corresponding mechanisms that translate the movements of the handle into movements of the workbench legs. Each workbench also has two push-buttons or actuators which help locking the moveable members of the workbench in various desired positions. Additionally, the tops of the workbenches have different slots and holes for attaching different power and traditional tools to the workbenches and are marked for various measurements and/or calculations which eliminates the need to use some basic tools while working on top of the workbench.
