Actuating Device Intermediate Gear Compact Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuating devices with a gear-toothed rack combination often require a large protrusion of the toothed rack beyond the gear element, leading to inefficient use of space in pivot units or clamping devices, as there is no effective means to house the rack within a typical housing form.
Innovation Solution
Incorporating an intermediate gear element between the cylinder and the gear element, which cooperates with both the toothed rack and the gear element, allowing the toothed rack to be housed within the device despite a long displacement distance, thereby optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a gear-toothed rack combination is used without an intermediate gear element, then the structure is simple, but the toothed rack protrudes well beyond the gear element leading to large extension distance
Solution Approach 1:
An intermediate gear element is introduced between the toothed rack and the gear element. This intermediate gear acts as a mediator that transfers motion from the toothed rack to the gear element, enabling the toothed rack to be contained within a compact housing while maintaining the required displacement distance for the actuating element's pivot range.
2Length of moving object
If the toothed rack is extended to provide long displacement distance, then the pivot range of actuating element is sufficient, but the housing space is inefficiently used
Solution Approach 1:
The intermediate gear element is positioned within the housing in such a way that it allows the toothed rack to be nested or contained within the housing boundaries. The intermediate gear enables the rack's long displacement distance to be achieved while the rack itself remains housed, optimizing space utilization in the head area of the actuating device.
3Length of stationary object
If an intermediate gear element is added between the toothed rack and gear element, then the toothed rack can be housed within compact dimensions, but the device complexity increases
Solution Approach 1:
The intermediate gear element serves as a compact mediator that enables the toothed rack to be housed within the housing while providing the necessary displacement distance. Although it adds one component to the system, it resolves the spatial contradiction by enabling compact housing of the gear-toothed rack combination.

Function Achieved in This Case
This configuration enables the toothed rack to be guided inside the housing for a long displacement distance, providing a compact design and allowing for precise adjustment of the actuating element's pivot range while utilizing space efficiently.
Implementation Method 1
An intermediate gear element is situated between the cylinder and the gear element. The intermediate gear element cooperates, on one side, with the toothed rack and, on the other side, with the gear element.
