Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current component feeding systems for motor vehicle assembly lines are expensive due to the need for automation, require human intervention for trolley exchange, and are inefficient with varying component sizes and space allocation, posing safety concerns and necessitating restricted areas for trolley operation.
Innovation Solution
A component feeding system utilizing sorting trolleys with inclined chutes that facilitate the exchange of full and empty containers using gravity, eliminating the need for automation and manual handling, allowing for continuous operation without electrification and reducing operator involvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automation systems are implemented in the warehouse and at the assembly line, then productivity and sorting efficiency are improved, but device complexity and cost increase significantly
Solution Approach 1:
The system uses gravity-fed chutes that automatically direct containers to the correct trolleys without requiring automated guiding systems, sensors, or control mechanisms. The inclined planes and guide surfaces passively sort containers based on their destination, eliminating the need for complex automated sorting equipment while maintaining high productivity.
Solution Approach 2:
The sorting area is divided into multiple chutes, each dedicated to a specific trolley or destination. This segmentation allows simultaneous sorting of multiple container types to different trolleys, achieving high productivity through parallel processing without requiring a single complex automated system.
2Adaptability or versatility
If manual handling and trolley exchange operations are performed by persons, then flexibility and adaptability are maintained, but productivity decreases and safety concerns arise
Solution Approach 1:
The gravity-fed chutes automatically perform the sorting and loading function that would otherwise require manual handling. Containers slide down the inclined planes and are deposited into trolleys without human intervention, eliminating the need for operators to manually load containers while maintaining the flexibility to handle various container types and destinations.
Solution Approach 2:
The gravity-fed chute system acts as an intermediary between the warehouse storage area and the trolleys. It transfers containers from storage to trolleys automatically, reducing the need for direct human intervention in the material flow while preserving operational flexibility through the modular chute design.
3Reliability
If restricted areas are established for trolley operations, then safety of operators is improved, but ease of operation and access deteriorate
Solution Approach 1:
The gravity-fed sorting system extracts the sorting and loading function from the trolley operation area. By positioning chutes along the assembly line where containers can be sorted and loaded without trolleys needing to enter restricted zones, the system maintains operator safety while allowing broader access to the assembly line area for other operations.

AI summary
A component feeding system of at least an assembly line is described wherein the containers containing the components are moved by the force of gravity. The system comprises at least a loading station (3) at least a sorting trolley (5) to move the components and at least an assembly station (7). Both empty (91) and full (90) containers are retained up to the passage of the sorting trolley (5), thanks to check means cooperating with release means enabled by the weight of the empty (91) or full (90) containers themselves.
