Solution Overview
Problem
Conventional elevator deflecting modules are not adaptable to narrow shaft conditions, leading to wide construction issues and interference with shaft walls, requiring costly modifications.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If several rollers are arranged adjacent to one another in a conventional deflecting module, then the support means can be effectively guided, but the deflecting module becomes very wide and cannot be used in narrow shaft conditions
Solution Approach 1:
The deflecting elements are made displaceable relative to one another along the direction of the support means, allowing the module to adapt its width dynamically. The deflecting elements can move to adjust their positions, enabling the same guiding function to be achieved with a narrower overall width, thus resolving the contradiction between reliable guiding and compact size.
Solution Approach 2:
The deflecting module is divided into multiple independent deflecting elements that can be displaced relative to each other. This segmentation allows each element to be positioned optimally for guiding the support means while maintaining a compact overall structure, solving the width issue without compromising guiding effectiveness.
2Device complexity
If a fixed-width deflecting module is used, then the structure is simple, but it cannot be adapted to different shaft cross-sections
Solution Approach 1:
The deflecting elements are designed to be displaceable relative to one another, transforming the static structure into a dynamic one. This allows the module to adjust its configuration to match different shaft cross-sections while maintaining structural simplicity through the use of straightforward displacement mechanisms rather than complex adjustable structures.
Solution Approach 2:
The deflecting module with displaceable elements can be used across different shaft cross-sections and elevator configurations, making it a universal solution. The same basic structure with movable elements can adapt to various conditions, eliminating the need for multiple specialized modules for different shaft sizes.
3Ease of manufacture
If conventional deflecting modules are used, then they are designed for specific shaft configurations, but they require costly modifications when shaft conditions change
Solution Approach 1:
The displaceable deflecting elements allow the module to be manufactured once with a standard design and then adapted to different shaft conditions through simple displacement adjustments rather than requiring costly custom manufacturing for each shaft configuration. This maintains ease of manufacture while achieving high adaptability.
4Area of stationary object
If the deflecting module is designed for narrow shaft conditions, then space is saved, but the construction becomes more complex
Solution Approach 1:
The solution achieves narrow width through dynamic displacement of deflecting elements rather than through a permanently compact fixed structure. This maintains construction simplicity while achieving space savings, as the elements move into position only when needed rather than requiring a permanently complex compact design.

AI summary
A deflecting module has deflecting elements that are displaceable relative to one another. The deflecting elements are mutually supported, wherein at each side the outermost deflecting element is carried by a bearing plate. Each deflecting element has a housing which carries an axle and, for the mutual displaceability, has on one side a groove and on the other side a cog. A deflecting roller is rotatably arranged on the axle for guiding and deflecting elevator car and counterweight support elements, for example a flat belt, and producing a change of direction of the support elements.
