Portable Work Table With Movable Second Rest for Long Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable work tables lack versatility and adequate support for machining long or heavy workpieces, especially when used with semi-stationary electrical tools.
Innovation Solution
A portable work table with a carrier structure and a second rest that can be selectively positioned as a workpiece rest or support, allowing for versatile configurations including a flat work surface and additional support for long workpieces, and facilitating easy transport with semi-stationary tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable work table is designed with a compact structure for easy transport, then portability is improved, but the ability to support long or heavy workpieces deteriorates
Solution Approach 1:
The work table is divided into a stationary base structure and a movable second rest that can be detached or repositioned. This segmentation allows the main table to remain compact for transport while the separate second rest can be added when long workpiece support is needed, resolving the contradiction between portability and workpiece support capability
Solution Approach 2:
The second rest is designed to be selectively movable between different positions (attached to extend support length, or detached/repositioned for compact storage). This dynamic configuration allows the work table to adapt between a compact portable state and an extended state capable of supporting long workpieces, eliminating the need for a permanently large structure
2Ease of operation
If semi-stationary electrical tools are made compact for transportability, then ease of transport is improved, but the dimensions of the workpiece rest are greatly limited
Solution Approach 1:
Instead of extending the workpiece rest length in the horizontal dimension, the invention utilizes the vertical dimension by allowing the second rest to be positioned at different heights and angles. This enables long workpieces to be supported through vertical adjustment and angular positioning rather than purely horizontal extension, accommodating compact tool designs while still providing adequate support length
3Adaptability or versatility
If multiple configurations are added to increase versatility, then adaptability is improved, but device complexity increases
Solution Approach 1:
The second rest serves multiple functions: it can be attached to the stationary rest to extend support length, positioned independently to provide localized support, or detached entirely for compact storage. This multi-functionality provides versatile configuration options without requiring multiple separate components, as one element performs various roles based on its positioning and attachment state

AI summary
A portable worktable having a support structure with a table operating assembly, in which the portable worktable can be positioned on a stand surface, and a support, which extends along a longitudinal direction and a width direction. The support includes a first support and the support structure can be moved into a first working configuration for using the portable worktable as a table and a second working configuration for using the portable worktable as an underlying surface at a height near the floor. The portable worktable can be moved into a transport configuration in which the portable worktable can be manually moved into a tilting position and can be moved relative to the stand surface. The portable worktable has a second support, which can be moved into a first support position, in particular a workpiece support position, or a second support position, in particular a workpiece stabilizing position.
