Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual labor and individual skills are used for elevator installation and maintenance, then flexibility and adaptability are maintained, but installation and maintenance quality varies significantly
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the elevator system including 3D models of the physical environment and elevator components. This digital representation is used to generate standardized installation and maintenance procedures, ensuring consistent quality across different installations while reducing dependence on individual worker skills.
Solution Approach 2:
The system performs preliminary planning by generating installation and maintenance procedures before actual work begins. The digital twin allows virtual simulation and preparation of procedures, enabling workers to follow pre-planned, optimized steps that ensure consistent quality outcomes.
2Reliability
If experienced personnel perform manual tuning and installation tasks, then satisfactory results are achieved, but training requirements and labor costs increase
Solution Approach 1:
The system provides real-time feedback to workers through augmented reality glasses during installation and maintenance tasks. The digital twin compares actual work progress against planned procedures, providing immediate guidance and confirmation, which reduces the need for extensive training while ensuring reliable outcomes.
Solution Approach 2:
The digital twin acts as an intermediary between the planning system and the worker. It translates complex technical requirements into step-by-step visual instructions that workers can follow easily, reducing the knowledge gap between experienced and inexperienced personnel.
3Productivity
If all work is performed manually without digital assistance, then simplicity is maintained, but work time and potential for errors increase
Solution Approach 1:
The patent replaces manual mechanical processes with digital systems. The digital twin and augmented reality interface substitute for manual measurement, calculation, and procedure planning, enabling workers to focus on execution while the digital system handles complex planning and monitoring functions.

AI summary
A method and a system provide assistance to a user during installing, maintaining, and/or commissioning of an elevator system. The method includes creating a digital representation, such as a digital twin, of the elevator system and its physical environment, such as the current or the future physical environment. The method also includes configuring a display device, which includes or is connected to an optical sensor, such as a digital camera, to run the digital representation, sensing, by the optical sensor, a portion of the physical environment, and comparing the portion to a corresponding portion of the digital representation, the portion being arranged to be visible on the display device.
