Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile assembly trolleys are not designed to handle high loads of building elements and lack flexibility, particularly when navigating through shallow openings or rooms with limited height, often requiring manual heavy lifting that is time-consuming and hazardous.
Innovation Solution
A mobile assembly trolley with a gear construction and hydraulic/pneumatic displacement mechanisms that allow horizontal and vertical movement, tilting, and adjustable tool holders with replaceable tools, enabling efficient handling and positioning of heavy building elements through the use of a gear construction with a curved profile and multiple displacement designs, including hydraulic cylinders for enhanced maneuverability and load-bearing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual heavy lifting is used to handle building elements, then the building process can proceed, but the speed of the building process is lowered and it becomes harmful or dangerous for personnel
Solution Approach 1:
The patent replaces manual mechanical lifting with an automated mobile assembly trolley equipped with hydraulic cylinders and displacement mechanisms. The trolley mechanically handles building elements through structured mechanical systems including turning joints, displacement designs, and tool holders, eliminating the need for personnel to perform manual heavy lifting while maintaining building process productivity
Solution Approach 2:
The assembly trolley is designed to autonomously handle building elements without requiring personnel intervention for lifting operations. The self-propelled trolley with integrated displacement mechanisms and tool holders performs self-service functionality by automatically positioning and maneuvering heavy building elements, thereby improving safety while maintaining construction speed
2Ease of operation
If current machines are used for element mounting, then lifting and holding tasks can be automated, but the machines lack flexibility in manoeuvrability and duration of function
Solution Approach 1:
The patent implements dynamic flexibility through a mobile assembly trolley with movable carrying profiles, turning joints, and displacement mechanisms that can adapt to varying operational requirements. The trolley's movable components and adjustable tool holders enable it to maneuver in different configurations and operate for extended durations, providing both automation and adaptability simultaneously
Solution Approach 2:
The assembly trolley is designed as a universal platform capable of performing multiple functions including lifting, holding, maneuvering, and positioning various types of building elements. The tool holder can accommodate different tools, and the displacement mechanisms can handle diverse element types and weights, making the machine adaptable to different mounting tasks while maintaining automated operation
3Ease of operation
If current machines are used in rooms with limited room height, then element mounting can be performed, but the machines cannot be used due to lack of ability for tilting
Solution Approach 1:
The patent incorporates dynamic tilting capability through turning joints and displacement mechanisms that allow the carrying profile and tool holder to tilt and rotate. This dynamic adjustment enables the trolley to operate in rooms with limited height by tilting the carrying profile to navigate through shallow openings while maintaining the ability to perform element mounting operations
Solution Approach 2:
The assembly trolley introduces tilting and rotation dimensions to overcome height limitations. By adding the ability to tilt the carrying profile and rotate the tool holder around horizontal and vertical axes, the system transforms the operational space from strictly vertical to multi-dimensional, enabling access to limited height spaces while maintaining mounting capability
4Strength
If a mobile assembly trolley with hydraulic cylinders and displacement mechanisms is used, then heavy building elements can be handled, but the device complexity increases
Solution Approach 1:
The patent employs hydraulic cylinders as the actuating mechanism to generate the necessary force for handling heavy building elements. The hydraulic system provides high strength and load-bearing capacity through fluid pressure, enabling the trolley to lift and maneuver heavy elements while the centralized hydraulic power unit efficiently manages the complexity of the actuation system
Solution Approach 2:
The assembly trolley is divided into modular segments including the frame, carrying profile, tool holder, and displacement mechanisms. This segmentation allows each component to be independently optimized and maintained, reducing overall system complexity while maintaining the strength required for handling heavy building elements through distributed mechanical advantage
