Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climbing devices for scaffolding and formwork systems face issues with hydraulic hose management, including leakage, fouling, and power loss due to long, flexible hoses, which require frequent maintenance and calibration to maintain synchronization and safety standards.
Innovation Solution
The implementation of a hydraulic unit with a built-in hydraulic tank, electric motor, and pump, eliminating the need for long hoses by using rigid connections and integrating the system directly onto the climbing rail, allowing for independent operation and self-sufficiency with electrical power and control systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If long flexible hydraulic hoses are used to connect hydraulic cylinders to carrier rails, then the system can be assembled with separate components, but leakage and fouling occur leading to frequent maintenance and operational halts
Solution Approach 1:
The patent combines the hydraulic tank, hydraulic pump, and hydraulic cylinder into a single integrated hydraulic unit that is directly mounted on the climbing rail. This eliminates the need for long flexible hoses and separate component connections, thereby preventing leakage and fouling while maintaining assembly capability.
Solution Approach 2:
The patent extracts the hydraulic connections from the flexible hose system and integrates them directly into the climbing rail structure through the mounted hydraulic unit. This removes the vulnerable hose connections from the system while preserving the functional separation of components.
2Adaptability or versatility
If meter-long pressure hoses are used in the hydraulic system, then component flexibility is maintained, but power losses occur requiring compensation and reducing climbing/lifting force
Solution Approach 1:
By integrating the hydraulic pump and tank directly onto the climbing rail in a single mounted unit, the patent eliminates long pressure hoses and their associated power losses. The hydraulic components remain functionally separate but are positioned to eliminate inefficient fluid transmission paths.
3Force
If multiple hydraulic cylinders are used for synchronized operation, then climbing force is distributed, but laborious calibration is necessary to ensure synchronous operation
Solution Approach 1:
The patent incorporates sensors that detect the position of the climbing platform and provide feedback to a control unit. This closed-loop control system automatically adjusts the operation of multiple hydraulic cylinders to maintain synchronous operation, eliminating the need for manual calibration while distributing climbing force effectively.
4Reliability
If hydraulic components meet stringent safety requirements for personnel transport, then safety is ensured, but maintenance and servicing costs become very high
Solution Approach 1:
The patent integrates the hydraulic tank, pump, and cylinder into a single sealed hydraulic unit mounted on the climbing rail. This integrated design reduces the number of connection points and potential failure modes, maintaining high safety standards while reducing the complexity and cost of maintenance and servicing.
