Solution Overview
Problem
Existing elevator components are difficult to accurately install and position on-site due to their complexity, increasing the workload and potential for errors during assembly.
Innovation Solution
A modular elevator assembly design featuring a bottom module, top module, and intermediate modules with guide rails that include a connection structure with protrusions and recesses for easy alignment and connection, allowing for pre-assembled components to be hoisted and assembled sequentially, reducing on-site operations and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If elevator components are manufactured separately and assembled on-site through welding or connecting, then the elevator can be customized to fit different building requirements, but the on-site workload increases and installation accuracy decreases
Solution Approach 1:
The elevator system is divided into modular components (elevator car, counterweight, guide rails, landing doors, etc.) that can be independently manufactured and then assembled on-site. Each module is designed with standardized connection interfaces that enable quick assembly without complex welding operations, thus reducing on-site workload while maintaining customization capability.
Solution Approach 2:
Elevator components are pre-assembled into complete modules at the manufacturing site before being transported to the installation location. The guide rails are pre-installed on the elevator car frame, and landing doors are pre-mounted on their respective frames. This preliminary assembly reduces the complexity of on-site operations while allowing the entire module to be customized for different building requirements.
2Adaptability or versatility
If elevator components are manufactured separately and assembled on-site, then flexibility in installation location is achieved, but installation accuracy and positioning precision deteriorate
Solution Approach 1:
The connection interfaces of the modular components are equipped with precise positioning features such as guide grooves, alignment pins, and standardized mounting holes. These localized precision features ensure that when modules are assembled on-site, they automatically align accurately without requiring complex measurement and adjustment operations, thus maintaining high installation accuracy while allowing flexibility in installation location.
3Strength
If traditional separate manufacturing and on-site welding is used, then structural strength can be achieved, but the assembly complexity and time consumption increase
Solution Approach 1:
Multiple elevator components are pre-assembled into integrated modules at the manufacturing site. The guide rails, elevator car frame, landing doors, and other components are combined into complete modules with standardized connection interfaces. This merging reduces the number of separate assembly operations required on-site while maintaining the structural strength through pre-engineered connections that eliminate the need for complex welding procedures.
