Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport bags for suspended conveyor systems are complex, energy-inefficient, noisy, and require numerous safety systems, with issues in loading, unloading, and stability, leading to operational failures.
Innovation Solution
A transport bag with a roller chassis supported by a pair of rollers, featuring an upper coupling that ensures secure driving and tilting prevention, along with a joint connection between the base body and holding plate, allowing for reliable operation on gradients and efficient loading/unloading through sliding surfaces and arc-angle switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional carrying bag with support frame and projections is used, then the feeding opening can be opened at the feeding station, but the goods to be conveyed can fall out and the structure becomes complex
Solution Approach 1:
The carrying bag is divided into functional segments: the support frame for structural integrity, the feeding opening for material input, and the closed bottom with side walls for containment. This segmentation allows each part to perform its specific function while simplifying the overall design compared to prior art.
Solution Approach 2:
Instead of having an open bottom structure that requires complex loading mechanisms, the patent inverts the approach by providing a closed bottom with side walls. This inversion simplifies the loading process and prevents material spillage while maintaining ease of operation at the feeding station.
2Device complexity
If no side walls are provided in the carrying bag, then the structure is simpler, but the goods to be conveyed can fall out
Solution Approach 1:
The carrying bag applies local quality by providing side walls only in the lower region where material containment is needed, while keeping the upper region open for feeding operations. This localized approach maintains simplicity where it matters least while providing reliability where it is most needed.
3Ease of operation
If a highly complicated loading station is used, then the carrying bag can be loaded and unloaded, but the connection of drivers to the carrying bag is not ensured reliably
Solution Approach 1:
The carrying bag is designed with pre-integrated coupling elements that align with the conveyor drivers before loading occurs. This preliminary arrangement ensures reliable connection is established automatically during the loading process, eliminating the need for complex loading stations while maintaining connection reliability.
4Adaptability or versatility
If the carrying bag is designed for suspended transport, then it can be moved on a conveying rail, but it requires numerous safety systems and is noisy
Solution Approach 1:
The patent extracts and eliminates unnecessary safety systems and noise-generating components from the suspended transport design. By simplifying the structure to essential elements (support frame, feeding opening, closed bottom with side walls), the design maintains suspended transport capability while reducing noise and operational failures.

AI summary
The invention relates to a transport bag (28) having a roll running gear (1) which comprises only one pair of rolls (3) on which it is oscillatingly mounted in the transport rail (33). The upper coupling (2) of the transport bag (28) is located above the rolls (3) and enables driving and transport by means of a conveying element (29) which preferably has a commercially available roller chain having driver pins. The disengagement of the drivers and the upper coupling parts (2) is prevented by the design of the transport bag (28) in that the transport bag (28) generates a sufficient torque (M1) around the roll axis (4), and the permissible inclination of the upper coupling (2) relative to the vertical (36) during transport along conveyor paths is not exceeded, so that more reliable entrainment of the transport bag (28) is guaranteed. The curved-angle track switches (80) for the conveyor system have few parts and are therefore cost-effective and operationally reliable.
