Vise Table With Switchable Threaded And Unthreaded Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vises with threaded mechanisms require time-consuming rotational force to move the movable jaw, limiting efficiency in securing objects, and there is a need for a portable work table with an integrated vise that addresses these shortcomings.
Innovation Solution
A vise table with a vise head block connected via a threaded guide, allowing selective operation in threaded or unthreaded modes, where the threaded mode requires rotational force and the unthreaded mode allows direct force application for movement, facilitated by an activation mechanism with a trigger tooth and engagement block.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a threaded mechanism is used to move the movable jaw, then the vise can securely hold objects with precise positioning, but the operation becomes time-consuming due to the small diameter of the threaded mechanism relative to the travel distance
Solution Approach 1:
The vise mechanism dynamically switches between two operational modes: threaded mode for precise positioning and unthreaded mode for rapid movement. The movable jaw can engage with the threaded guide for precision work or disengage to slide freely along guide rails for quick repositioning, allowing the system to adapt its characteristics based on operational needs
Solution Approach 2:
The friction parameter between the movable jaw and threaded guide is changed by switching between engaged and disengaged states. When engaged, high friction enables precise positioning through threading; when disengaged, low friction allows rapid sliding movement, thus changing the friction parameter to resolve the contradiction between precision and speed
2Productivity
If the movable jaw is moved by applying force directly to the jaw, then the operation is faster and more efficient, but the vise loses the secure holding capability and precise positioning provided by the threaded mechanism
Solution Approach 1:
The vise dynamically transitions between unthreaded mode for rapid movement and threaded mode for secure holding. The movable jaw can slide freely along guide rails when the threaded guide is disengaged for high-speed repositioning, then engage with the threaded guide to convert to precise, secure positioning, thus dynamically switching between productivity and reliability modes
Solution Approach 2:
The threaded guide acts as an intermediary mechanism that can be selectively engaged or disengaged. When engaged, it mediates between the applied force and the movable jaw to provide secure holding and precise positioning; when disengaged, it allows direct force application for rapid movement, thus serving as a controllable intermediary that resolves the contradiction between efficiency and reliability
3Adaptability or versatility
If a portable work table with an integrated vise is designed, then the system becomes more versatile and space-efficient, but the device complexity increases
Solution Approach 1:
The vise mechanism is merged with the work table structure, where the table block and vise head block form an integrated assembly. The threaded guide, guide rails, and activation mechanism are combined into a unified structure that provides both table and vise functions, reducing overall system complexity while enhancing versatility
Solution Approach 2:
The integrated vise table provides multiple functions within a single device: it serves as both a work surface and a securing mechanism. The movable jaw can quickly reposition for different work positions and securely hold various objects, making the device universally applicable for different woodworking tasks while maintaining relatively simple construction

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and versatile object holding by allowing quick, broad movements in unthreaded mode and precise tightening in threaded mode, enhancing user experience and productivity.
Implementation Method 1
The vise head block is operably connected to the table block via a threaded guide, and wherein said vise head block is configured to move between an open position and a closed position. Rotating the threaded guide in the first direction moves the vise head block toward the open position. Rotating the threaded guide in the second direction moves the vise head block toward the closed position.

AI summary
The present invention relates to an integrated vise and work table. The disclosed vise table allows an operator to clamp an object in place so that the same can worked on in a hands-free method. The vise table includes a table block, a vise head block, a threaded guide, a rotator, and an activation mechanism that allows the operator to selectively vise in a threaded mode or in an unthreaded mode. In the threaded mode, the vise head block may only be moved by rotating a threaded guide. In the unthreaded mode, the vise head block may only be moved by applying force to the vise head block in the desired direction of movement.
