Jacking Tool Fine-Adjustment Mechanism for Bidirectional Height Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jacking tools can only achieve downward fine adjustment, requiring multiple steps and being cumbersome when upward adjustments are needed, making them inconvenient for precise height adjustments.
Innovation Solution
A jacking tool with a lifting portion and adjustment mechanism allowing both upward and downward fine adjustments through a threaded connection and bevel gear system, enabling direct control of the lifting plate's movement via an actuator for precise height adjustments without additional steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a jacking tool uses a single-direction adjustment mechanism (only downward fine adjustment), then the structure remains simple, but the ease of operation deteriorates when upward adjustment is needed
Solution Approach 1:
The adjustment mechanism transitions from a static single-direction design to a dynamic bidirectional design. The threaded rod with manual screwing mechanism allows the lifting plate to move both upward and downward relative to the lifting portion, enabling flexible adjustment in either direction based on operational needs.
Solution Approach 2:
The adjustment mechanism is designed to perform multiple functions: both upward fine adjustment and downward fine adjustment are achieved through the same threaded rod and screwing mechanism. This multi-functional design eliminates the need for separate adjustment mechanisms for different directions, balancing complexity and operational ease.
2Productivity
If a jacking tool requires multiple operation steps for adjustment, then the mechanism can be simple, but the loss of time increases during adjustment operations
Solution Approach 1:
The threaded rod mechanism allows continuous adjustment of the lifting plate position by manual screwing. The user can smoothly control the lifting plate's movement in either direction without discrete steps, enabling continuous fine adjustment and reducing the time required compared to multi-step mechanisms.
Solution Approach 2:
The adjustment mechanism is pre-configured with a threaded rod and screwing mechanism that enables immediate bidirectional adjustment. The lifting plate can be quickly positioned upward or downward from its current location without requiring multiple sequential operations, reducing adjustment time.
3Manufacturing precision
If a jacking tool uses a threaded rod mechanism for fine adjustment, then the manufacturing precision improves, but the device complexity increases
Solution Approach 1:
The threaded rod mechanism is designed to be manually operated by the user through screwing motions. The lifting plate's precise positioning is achieved through the user's own manual action on the threaded rod, eliminating the need for complex motorized or automated adjustment systems while maintaining high manufacturing precision.
Applied Scientific Principles
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 simple, fast, and precise up-down fine adjustments of jacking height, improving user convenience and accuracy by allowing direct control of the lifting plate's movement relative to the lifting portion.
Implementation Method 1
The lifting plate is in threaded connection with the threaded rod; and when the drive assembly drives the threaded rod to rotate clockwise or anticlockwise, the lifting plate in threaded connection to the threaded rod moves up and down along the threaded rod
Implementation Method 2
The actuation component includes a linkage bevel gear, an actuating bevel gear, and an actuating arm arranged on the actuating bevel gear; the linkage bevel gear is arranged on the threaded rod; the actuating bevel gear is meshed with the linkage bevel gear; when the actuating arm is actuated to rotate, the actuating bevel gear is driven to rotate; the rotation of the actuating bevel gear can drive the linkage bevel gear and the threaded rod to rotate synchronously
