Furniture Lift Container Rollers for Low-Force Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture containers for mobile lifts require significant manual force and pose a risk of injury due to high friction during loading and unloading, and furniture can shift or bump against container edges, necessitating additional effort.
Innovation Solution
Incorporation of rotatably mounted loading roller elements angled towards the loading direction, allowing furniture to be rolled onto and off the container base, reducing friction and facilitating easy loading and unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If furniture is pushed onto or off the container base across the loading flap surface, then loading and unloading can be performed, but significant friction requires considerable manual force and poses injury risk
Solution Approach 1:
The patent introduces a loading ramp as an intermediary element between the loading flap and the furniture piece. This ramp provides a gradual inclined surface that reduces the friction force during loading/unloading operations, allowing furniture to be pushed with significantly less manual force compared to direct contact with the horizontal loading flap surface.
Solution Approach 2:
The patent adds a spatial dimension by introducing an inclined loading ramp instead of direct horizontal pushing. The ramp creates a gradual slope that distributes the force requirement over a longer distance and reduces the friction coefficient, transforming the loading operation from a high-force horizontal push to a lower-force inclined push.
2Ease of operation
If furniture is pushed across the loading flap surface, then loading and unloading can be performed, but furniture can shift during the process
Solution Approach 1:
The loading ramp acts as a stabilizing intermediary that provides a controlled transition surface. The gradual incline prevents sudden shifts and bumps that occur when furniture directly contacts the loading flap edge, maintaining better position stability throughout the loading/unloading process.
3Productivity
If furniture is pushed against the loading flap edge during loading/unloading, then furniture can be transferred, but additional lifting effort is required
Solution Approach 1:
The loading ramp extends the transfer path in the vertical dimension, creating a gradual inclined surface that eliminates the need for vertical lifting at the loading flap edge. Furniture is pushed up the incline rather than lifted vertically, reducing the additional force required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly reduces the force required for loading and unloading, minimizing the risk of injury and preventing furniture from colliding with container edges.
Implementation Method 1
The respective piece of furniture is placed on the at least one loading roller element that protrudes from below through the floor plane. The piece of furniture is then rolled, at least partially, along the furniture container in the loading direction or against the loading direction using the loading roller element. This massively reduces the friction and force required to overcome the previously difficult loading and unloading process

AI summary
The invention relates to a furniture container (2) for a mobile furniture lift. The furniture container has a container base (4) with a base surface (6) arranged in a floor plane (BE) and a loading flap (8). The loading flap is pivotally mounted relative to the container base (4) about a hinge axis (KA) from a loading position, in which furniture (10) can be loaded onto the container base (4) in a loading direction (BR) parallel to the floor plane (BE) via a loading flap surface (12) of the loading flap (8), which is aligned parallel to the loading direction (BR), to a closed position, in which the loading flap surface (12) is angled relative to the loading direction (BE).According to the invention, the furniture container has at least one loading roller element (14) rotatably mounted at least relative to the container base (4) about a rolling axis (RA) which is angled towards the loading direction (BR) and which is cut off from the floor plane (BE) at least in the loading position of the loading flap (8).
