Elevator Component Packaging by Assembly Step and Reusable Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for elevator components are inefficient, leading to missing or damaged components during installation due to improper grouping and protection, causing delays and damage during transport and unpacking.
Innovation Solution
A method for packaging elevator components by grouping them according to specific assembly steps, using reusable, component-specific packaging with secure recesses and fastening devices, ensuring all necessary components are present and protected during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elevator components are packaged using conventional methods without systematic grouping, then packaging simplicity is maintained, but components may be missing or damaged during installation due to improper grouping and protection
Solution Approach 1:
The packaging system is segmented into multiple hierarchical levels: individual component packaging, group packaging by assembly step, and complete system packaging. Each level addresses specific protection and organization needs, ensuring components are properly grouped according to assembly sequences while maintaining manageable packaging units.
Solution Approach 2:
Components are pre-grouped into packages according to assembly steps before delivery to the construction site. This preliminary organization ensures that all components needed for each assembly step are available together, preventing installation delays and damage during unpacking.
2Productivity
If components are grouped into multiple packages by assembly step, then component availability for installation is improved, but determining which components go together becomes more complex
Solution Approach 1:
The packaging organization is predetermined based on assembly steps, with each package clearly labeled and containing all components needed for specific installation phases. This eliminates the need for complex on-site decision-making about component grouping.
Solution Approach 2:
Packaging documentation and labeling systems serve as intermediaries between the packaging system and installation team, providing clear instructions on which components belong together without requiring complex judgment calls during unpacking.
3Reliability
If reusable packaging with component-specific recesses is used, then component protection during transport is improved, but packaging design and manufacturing become more complex
Solution Approach 1:
The reusable packaging features component-specific recesses and fastening devices tailored to each component's shape and characteristics. This localized customization provides optimal protection for each component while maintaining a standardized overall packaging structure that can be manufactured efficiently.
Solution Approach 2:
The reusable packaging system is designed to accommodate multiple different elevator components through standardized interfaces and adjustable features. A single packaging unit can serve multiple functions across different assembly steps, reducing the total number of unique packaging designs needed.
4Reliability
If components are securely fastened in reusable packaging, then damage during transport and unpacking is reduced, but unpacking time and effort increase
Solution Approach 1:
The fastening devices are designed to be pre-positioned and easily activated during unpacking. Components are secured in a way that maintains protection during transport but allows for rapid release when needed, minimizing unpacking time while ensuring component integrity.
Solution Approach 2:
The packaging system transitions from a secured state during transport to an easily accessible state during installation. Fastening mechanisms are designed to be dynamically adjustable, providing strong holding force during transit but allowing quick release at the construction site.

AI summary
The present invention relates to a method for packaging elevator components (K) of a complete elevator system in several packages (P). To improve the packaging, it is proposed that the elevator components (K) required for the assembly of an elevator system be assigned to a respective assembly step (M), that the elevator components (K) be packed into a package (P) that, at the installation site, belong to one or two successive assembly steps (M), and that, for packaging the elevator components (K) in the respective packages (P), at least partially, packaging means (VM) are used as reusable packaging (4), in which the elevator components (K) to be packed in a package (P) are at least partially placed in component-specifically shaped receptacles, in which the elevator components (K) placed therein are held without play or at least almost without play during transport.
