Solution Overview
Problem
Existing lifting systems for heavy objects, such as prefabricated buildings, face limitations in lifting height, safety, and stability, leading to potential damage during transfer due to low lifting capacity and lack of secure fixation, resulting in time-consuming processes and risk of structural damage.
Innovation Solution
A lifting unit featuring a telescopic fastening column, hydraulic lifting cylinders, and adjustable fastening plates and chains ensures secure fixation and stability, allowing for a three-point lifting system that prevents horizontal tilting and lateral deflection, enabling safe and efficient transfer of heavy objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a lifting system with beams and support plates is used, then heavy objects can be lifted, but the lifting height is limited and the process becomes time-consuming when repeated lifts are needed
Solution Approach 1:
The lifting device employs a telescopic column with nested tubes that can extend to great heights, allowing the lifting height to be increased without requiring multiple lifting operations. The inner tube slides within the outer tube, enabling continuous height adjustment from 0.5m to 3m or more in a single lifting action.
Solution Approach 2:
The lifting device uses a hydraulic cylinder that can dynamically adjust the lifting height and speed. The hydraulic system provides continuous variable control over the lifting process, allowing the device to adapt to different lifting requirements and eliminate the need for repeated lifting operations.
2Device complexity
If a simple lifting device without fixation mechanisms is used, then the device complexity is reduced, but the safety and stability of the lifted object cannot be guaranteed
Solution Approach 1:
The lifting device incorporates fastening plates and chains that are pre-positioned and can be engaged before lifting begins. The fastening plates are attached to the telescopic column at various heights, allowing the lifted object to be secured in advance, preventing swinging and potential damage during the lifting and transfer process.
Solution Approach 2:
The lifting device combines multiple functions into a single integrated system: the telescopic column provides lifting, the fastening plates provide securing, and the hydraulic cylinder provides controlled movement. This merging of functions ensures both safety and efficiency without requiring separate complex systems.
3Force
If lateral supports and a square support plate are used, then the lifting device can support heavy weight, but lateral twisting and falling cannot be prevented
Solution Approach 1:
The lifting device uses a triangular arrangement of the telescopic column and support structures, which provides inherent lateral stability. The triangular geometry resists twisting forces more effectively than square or rectangular arrangements, preventing lateral instability while maintaining heavy load support capacity.
Solution Approach 2:
The lifting device adds vertical dimension through the telescopic column, allowing the lifted object to be raised above potential lateral instability zones. By lifting the object higher, the device clears obstacles and reduces the risk of lateral twisting and falling during transfer operations.
4Device complexity
If the lifted object is not attached to the lifting device, then the device complexity is reduced, but the object may swing during lifting and transfer causing damage
Solution Approach 1:
The lifting device uses fastening chains as intermediaries between the lifted object and the telescopic column. These chains provide a flexible yet secure connection that prevents swinging while accommodating slight movements and misalignments during the lifting and transfer process.
Solution Approach 2:
The lifting device replaces complex mechanical fixation systems with a simpler hydraulic control system that maintains tension on the fastening chains. The hydraulic cylinder can dynamically adjust the lifting force to keep the object securely attached without requiring complex mechanical locking mechanisms.
