Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional guide rail installation methods are used, then installation can be performed, but alignment precision deteriorates and safety risks increase
Solution Approach 1:
The patent introduces a guide rail installation apparatus as an intermediary device between the installer and the guide rail sections. This apparatus includes alignment mechanisms and positioning features that mediate the installation process, ensuring precise alignment and secure installation while reducing direct manual handling risks.
Solution Approach 2:
The guide rail installation apparatus incorporates self-aligning features and automatic positioning mechanisms that enable the system to correct alignment errors automatically during installation, reducing dependency on manual precision and enhancing both alignment accuracy and installation safety.
2Productivity
If construction time elevators are implemented early, then transportation capability is improved, but installation complexity increases
Solution Approach 1:
The patent divides the guide rail installation into modular sections that can be installed independently and sequentially. The guide rail installation apparatus is designed to handle individual guide rail sections, allowing for staged installation as construction progresses, thereby reducing overall installation complexity while maintaining early transportation capability.
Solution Approach 2:
The patent incorporates preliminary alignment features and pre-positioning mechanisms in the guide rail installation apparatus that prepare the installation path in advance. This preliminary action simplifies subsequent installation steps and enables earlier operational readiness of the construction time elevator.
3Ease of operation
If manual guide rail alignment is performed, then installation flexibility is maintained, but installation time increases
Solution Approach 1:
The patent replaces manual mechanical alignment operations with automated alignment mechanisms in the guide rail installation apparatus. These mechanisms use mechanical guides, alignment sensors, and automated positioning systems to achieve precise alignment quickly, maintaining operational flexibility while dramatically reducing installation time.

AI summary
The invention relates to a method for constructing an elevator including installing an elevator car, a counterweight, guide rail lines, a hoisting machine in a first position, and a first hoisting roping, connecting the first hoisting roping to the elevator car and counterweight; and transporting the elevator car vertically in the hoistway; removing the hoisting machine from the first position and disconnecting the first hoisting roping from the elevator car and counterweight; installing the hoisting machine, in a higher second position, and a second roping, connecting the second hoisting roping to the elevator car and counterweight; and transporting the elevator car vertically in the hoistway while the hoisting machine is in the second position using the hoisting machine and the second hoisting roping.
