Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor devices are expensive to manufacture due to complex and costly driver designs, requiring multiple carriers for smooth operation, which increases production costs and maintenance needs.
Innovation Solution
A modular conveyor device design featuring guide units with a single driver, where transport carriages can be driven in the connecting area of two guide units, allowing for simpler and cheaper construction, and enabling modular assembly with snap closures or screw connections, along with optional lift or transverse shifting functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple carriers are used in the transport carriage to ensure smooth operation during guide unit transitions, then the reliability of transport is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
A transfer roller is introduced as an intermediary component between guide units to enable smooth transport carriage transitions. This single intermediary roller eliminates the need for multiple carriers in the transport carriage, resolving the contradiction by providing the necessary transition function through a simple external mechanism rather than complex internal carriage design
Solution Approach 2:
The transition function is extracted from the transport carriage itself and placed in the guide unit infrastructure (via the transfer roller). This extraction allows the carriage to be simplified to a single carrier while the guide unit assumes responsibility for facilitating smooth transitions between guide units
2Adaptability or versatility
If a complex driver design with specific spring forces is used to adapt to different transport requirements, then the adaptability of the transport system is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The transfer roller is designed as a universal component that can serve multiple guide units and different transport carriage configurations. This single standardized component replaces the need for custom-designed drivers with specific spring forces, achieving adaptability through a simple, universally applicable mechanism that is easy to manufacture
Solution Approach 2:
The transfer roller is designed as a simple, inexpensive component that can be easily replaced if needed, eliminating the need for expensive, precisely engineered drivers. The simplicity of the roller design makes it economically advantageous while maintaining functional adaptability across different transport scenarios
3Reliability
If multiple carriers are required in the transport carriage to ensure continuous drive interaction, then the reliability of drive continuity is improved, but the productivity of manufacturing and maintenance deteriorates
Solution Approach 1:
The transfer roller acts as a mediator that ensures continuous drive interaction during guide unit transitions without requiring multiple carriers. This intermediary component bridges the gap between guide units, maintaining drive continuity while allowing the use of simpler, single-carrier transport carriages that are faster to manufacture and maintain

AI summary
The unit (3.1) has a guide rail, and endless drive units (5.1-5.3), which are arranged along the guide rail. The endless drive units are guided into a region of an end of the guide rail around rotatable deflection elements (9.1-9.8). The guide unit comprises a roller in the region of the end of the guide rail. Transport trolleys (2.1-2.3) provided in a connection region of the guiding unit are driven by the roller. The endless drive units are driven by the rotatable deflection elements. The roller is formed as a friction roller for cooperation with a counter surface of the transport trolleys. An independent claim is also included for a modular conveyor device for transporting loads.
