Wedge Drive Slide Positioning for Fast Working-Installation Changeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wedge drives require complex and time-consuming measures to transition from the working position to the installation position, necessitating additional components for position fixation, which is costly and inefficient.
Innovation Solution
A wedge drive design featuring a slide with a variable-position device and two stops, allowing for a single device to function as both a limiter in the working position and a bearing in the installation position, enabling easy conversion between positions without additional external fasteners, utilizing a fastener system with pocket holes for attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional wedge drive design is used to achieve the installation position, then the tool can be positioned for work, but complex measures and additional components are required making the process time-consuming and expensive
Solution Approach 1:
The variable-position device serves multiple functions: it acts as a limiter in the working position and as a support for the second stop in the installation position. This multi-functionality eliminates the need for separate components for each position, simplifying the overall device structure and reducing the number of parts required for position fixation.
Solution Approach 2:
The device is designed to be movable between two fixed positions (working position and installation position) rather than being permanently fixed. This dynamic capability allows the same component to serve different functions depending on its position, enabling easy transition between operational modes without complex reconfiguration.
2Reliability
If additional components are added to fix the installation position, then position stability is improved, but the cost and time required for implementation increases
Solution Approach 1:
The variable-position device provides position stability through its dual functionality: it limits the first stop in the working position and supports the second stop in the installation position. This eliminates the need for additional external fasteners or components, achieving reliable position fixation while reducing transition time and cost.
Solution Approach 2:
The device serves itself by providing both positioning functions through a single component. The variable-position device inherently provides the necessary support and limitation functions for both positions without requiring external assistance or additional components, thereby reducing implementation time and cost.
3Device complexity
If a single device is used for both limiting and supporting functions, then the number of components is reduced, but the device must perform multiple functions increasing its complexity
Solution Approach 1:
The variable-position device is designed to perform both limiting and supporting functions through its ability to occupy different positions. In the working position, it limits the first stop; in the installation position, it supports the second stop. This multi-functionality reduces the total number of components while maintaining the necessary functional versatility through positional adaptability.
Solution Approach 2:
The device achieves functional versatility through dynamic repositioning rather than structural complexity. By being able to move between two defined positions, the single device can perform different functions (limiting vs. supporting) without requiring multiple specialized components, thus reducing overall device complexity while maintaining adaptability.

AI summary
A wedge drive (1) has a slide upper part (4), a slide lower part (2), and a slide (3) arranged between the slide upper part (4) and the slide lower part (2). The slide (3) is movable between a closed and an open position in a working position. The slide (3) has a variable-position device (10), a first stop (30) and second stop (40), to obtain either the working position or an installation position. In the working position, the device (10) is positioned so that it is used as the limiter for the first stop (30) when the wedge drive (1) is actuated or is in its intended fully open position. In the installation position, the device (10) is positioned so that the second stop (40) supports itself on the device (10).
