Modular Guide Unit for Handling Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide units for handling modules, particularly large linear axes or long-stroke grippers, are economically feasible only in high quantities due to their specialized design, making production in small numbers costly.
Innovation Solution
A modular guide unit design featuring interchangeable support structures, guide rails, and connecting parts allows for easy dimensioning and replacement, enabling economical production by using different materials and configurations, such as truss-like elements and screw connections, to optimize weight and installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized aluminum profiles are used for guide units, then the guide unit achieves required precision and stability, but production cost increases significantly for small quantities
Solution Approach 1:
The guide unit is divided into separate modular components: support structures, guide rails, and connecting parts. These can be manufactured independently using standard materials and processes, then assembled. This segmentation allows economical production of individual components even in small quantities, while maintaining overall system precision through standardized interfaces and tolerance control.
Solution Approach 2:
The support structures are designed as universal base elements that can accommodate different guide rail configurations and lengths. The standardized support structures serve multiple functions: providing mounting surfaces, defining positional tolerances, and enabling various guide rail arrangements. This universality reduces the need for specialized components for each application, lowering production costs for small quantities.
2Productivity
If fixed-dimensional guide units are manufactured, then production efficiency increases for high quantities, but adaptability to varying requirements decreases
Solution Approach 1:
The guide unit system is designed with dynamic configurability through modular components. The support structures, guide rails, and connecting parts can be selectively combined to create guide units of different lengths and configurations. This dynamic assembly approach maintains high production efficiency through standardized components while providing full adaptability to varying application requirements.
Solution Approach 2:
By segmenting the guide unit into standardized modular components, the system enables both efficient production through repetition of standard parts and adaptability through different combinations. The same support structures and connecting parts can be used across multiple applications, while the overall configuration adapts to specific requirements.
3Ease of operation
If additional mounting elements are provided for drive units, then installation flexibility increases, but device complexity and number of parts increases
Solution Approach 1:
The mounting elements for drive units are integrated directly into the support structures. The support structures include built-in mounting surfaces, holes, or attachment features that eliminate the need for separate mounting brackets or additional fastening components. This merging reduces the total number of parts while maintaining installation flexibility through the inherent design of the support structures.
Solution Approach 2:
The support structures are designed with universal mounting capabilities that serve multiple functions: structural support, positional reference, and drive unit attachment. This multi-functionality eliminates the need for specialized mounting elements, reducing device complexity while maintaining installation flexibility across different configurations.

AI summary
The guide unit (10) has supporting structures (14) e.g. cast or milled parts, formed as planar elements. Guiding rails (12) e.g. extruded profile, are arranged on the supporting structures, where the guiding rails run parallel to ach other. Connecting parts (22, 24, 26) e.g. timber frame like planar elements, are connected with each other and are connected with the supporting structures. The connecting parts are arranged perpendicular to the supporting structures. A drive unit is arranged between the guiding rails and the connecting devices.
