Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product flow regulators are complex and costly due to high mechanical and electrical requirements, with inefficient transfer processes and noise-induced stress on products during direction changes and accumulation.
Innovation Solution
The product flow regulator features independently driven and self-controlled product carrier gondolas moving on stationary guide and transport rails, eliminating the need for mechanical transfer and contact-based accumulation, allowing continuous operation and flexible system design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional circulating chains and mechanical transfer devices are used to move product carrier gondolas, then the system can achieve continuous product flow, but the mechanical complexity and number of drives increase significantly
Solution Approach 1:
The patent replaces the conventional mechanical circulating chain system with an independent drive device on each gondola that engages with a stationary guide rail. This substitution eliminates the need for complex mechanical transfer devices and multiple drives, reducing overall system complexity while maintaining continuous product flow capability
Solution Approach 2:
The system divides the gondola transport function into independent units, where each gondola has its own drive mechanism. This segmentation allows each gondola to operate autonomously on the stationary guide rail, eliminating the need for a single complex mechanical system and reducing overall device complexity
2Ease of operation
If mechanical transfer devices are used for direction changes from vertical to horizontal, then the gondolas can be redirected, but the transfer process interrupts gondola circulation and reduces system performance
Solution Approach 1:
The patent replaces mechanical transfer devices with a stationary guide rail system that allows gondolas to change direction smoothly without interruption. The independent drive on each gondola enables direct engagement with the guide rail at any point, eliminating transfer interruptions and maintaining continuous circulation
Solution Approach 2:
The guide rail is pre-configured with engagement points at all necessary locations, allowing gondolas to change direction at any point without waiting for mechanical transfer cycles. This preliminary preparation of the guide rail structure enables immediate direction changes without interrupting circulation
3Reliability
If conventional mechanical piling up of product carrier gondolas is used for accumulation, then the system can buffer products during packaging interruptions, but noise and mechanical stress increase and cause vibrations that stress the products
Solution Approach 1:
The patent replaces mechanical piling up with a stationary guide rail system where gondolas accumulate by stopping at designated positions rather than physically stacking. The independent drive allows gondolas to hold position without mechanical contact with other gondolas, eliminating noise and vibration while maintaining buffering capability
Solution Approach 2:
The stationary guide rail acts as an intermediary that enables accumulation without direct mechanical contact between gondolas. The guide rail provides the buffering function through controlled stopping positions, eliminating the need for mechanical piling and reducing harmful vibrations and noise

AI summary
The product flow regulator (1) for buffering products has a frame (4), conveying means, and product carrier gondolas (6), which are conveyed filled with products from a product inlet area to a product outlet area and are conveyed back empty. The frame has a stationary guide track (5), along which the product carrier gondolas circulate in an independently controlled manner. The gondolas have driving means and electrical control devices, which enable individual independent circulation.
