Foldable Ramp Extension for Ergonomic Cart Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail warehouse processing systems face inefficiencies and safety issues due to multiple non-ergonomic touches and moves required to transport retail goods from storage to the sales floor, particularly in piece-pick operations where goods are directly picked into stocking carts and then moved to stores, leading to reduced warehousing efficiency and safety.
Innovation Solution
A cart transport vessel with a fixed platform and foldable ramp extension that allows for ergonomic and safe movement of carts, enabling direct picking from racks into the vessel, which can be coupled with a work machine for vertical lifting and movement, featuring a closed configuration for forklift engagement and a flat operator workspace.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed ramp structure is used for cart loading, then structural stability is maintained, but operator workspace accessibility is limited
Solution Approach 1:
The ramp structure incorporates a foldable extension that can transition between a deployed position (providing accessibility) and a retracted position (maintaining stability). This dynamic element allows the same structure to serve multiple operational states without requiring separate fixed structures for each function.
Solution Approach 2:
The ramp is divided into a fixed portion and a foldable extension portion. The foldable extension can be independently deployed or retracted, allowing the structure to adapt to different operational needs while maintaining the stability of the fixed portion.
2Productivity
If multiple separate structures are used for cart handling, then functional requirements are met, but handling efficiency is reduced
Solution Approach 1:
The invention combines the ramp structure, cart holding section, and operator workspace into a single integrated cart transport vessel. This merging eliminates the need for multiple separate structures (ramp, platform, workspace) and enables coordinated operation for efficient cart handling.
Solution Approach 2:
The cart transport vessel serves multiple functions simultaneously: it provides a ramp for cart loading, a platform for cart holding, and a workspace for operator activities. This multi-functionality reduces the number of separate structures needed and improves overall handling efficiency.
3Ease of operation
If manual cart transport is used, then equipment simplicity is maintained, but labor intensity increases
Solution Approach 1:
The cart transport vessel acts as an intermediary between manual operation and automated transport. It can be manually operated for simplicity but is designed to be coupled with work machines (forklifts) to automate the transport function, thereby reducing labor requirements while maintaining ease of operation through its standardized interface.
Solution Approach 2:
The vessel is designed with self-loading capabilities through the foldable ramp mechanism, where carts can be rolled onto the vessel without requiring complex automated loading systems. This self-service approach reduces the need for additional labor while maintaining operational ease.

Function Achieved in This Case
Enhances warehousing efficiency and safety by reducing non-ergonomic moves and improving the handling of retail goods from storage to the sales floor, allowing direct picking and efficient transportation of goods using the cart transport vessel with a work machine, thereby improving operational efficiency and safety.
Implementation Method 1
A foldable ramp extension is rotatably coupled to the front end of the fixed ramp

AI summary
A cart transport vessel includes a fixed platform configured to hold at least one cart, a fixed ramp located adjacent to the fixed platform and a foldable ramp extension that is rotatably coupled to a front end of the fixed ramp. In an opened configuration, a first side of the foldable ramp extension faces upwardly and is in planar alignment with a planar top surface of the fixed ramp and an opposing second side of the foldable extension faces downwardly. In a closed configuration, the foldable ramp extension is rotated so that the first side of the foldable ramp extension faces downwardly and is in contact with the planar top surface of the ramp section and the opposing second side of the foldable ramp extension faces upwardly to provide a flat operator workspace area that is configured to be stood on by an operator.
