Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-climbing systems for concrete structures require numerous switching gates for positioning adjusting elements, leading to complexity and a higher likelihood of errors in the switching process.
Innovation Solution
A self-climbing system with a linear drive connecting two climbing heads via a control rod, allowing for torque application to actuating elements at predetermined positions, eliminating the need for control links on the climbing rail and reducing friction and wear, while enabling independent actuation of the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerous switching gates are used for positioning adjusting elements, then the climbing mechanism can be positioned accurately, but the system complexity increases and error likelihood increases
Solution Approach 1:
The patent removes the switching gates from the climbing rail and extracts the positioning function to the control rod mechanism. The control rod directly connects to the adjusting element and provides positioning through its own mechanical structure rather than through multiple switching gates on the rail, thereby simplifying the overall system while maintaining positioning capability.
Solution Approach 2:
The control rod serves as an intermediary element between the linear drive and the adjusting element. It transmits the positioning function from the linear drive to the adjusting element without requiring multiple switching gates on the climbing rail, thus reducing system complexity while preserving positioning precision.
2Measurement precision
If numerous switching gates are used for positioning adjusting elements, then the climbing mechanism can be positioned accurately, but the likelihood of switching errors increases
Solution Approach 1:
By extracting the switching function from multiple distributed switching gates and consolidating it into a single control rod mechanism with limited switching points, the patent reduces the number of potential failure points. The control rod's direct mechanical connection to the adjusting element eliminates the need for complex switching gate interactions, thereby improving reliability.
Solution Approach 2:
Instead of having the adjusting elements switch positions by interacting with multiple switching gates on the rail, the patent inverts the approach by having the control rod directly actuate the adjusting elements at predetermined positions. This reversal of the switching mechanism reduces the complexity and error potential of the switching process.
3Ease of operation
If control links are used on the climbing rail for actuating adjusting elements, then the switching process can be controlled, but friction and wear on the climbing gear and rail increase
Solution Approach 1:
The patent extracts the control function from the climbing rail by removing the control links from the rail structure. The control rod is instead integrated into the climbing mechanism itself, allowing actuation of adjusting elements without requiring contact between control links and the climbing rail, thus eliminating the associated friction and wear.
Solution Approach 2:
The control rod acts as an intermediary that transfers the actuation force from the linear drive to the adjusting elements without requiring contact with the climbing rail. This eliminates the friction and wear that would occur between control links on the rail and the surrounding structure.
