Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-off devices for agricultural cargo require complex setups with multiple guiding profiles and hydraulic hoses, leading to increased weight, manufacturing effort, and complexity.
Innovation Solution
A push-off device utilizing two hydraulic cylinder arrangements with parallel hydraulic cylinder tubes and pistons, where the second hydraulic cylinder tube serves as both linear guidance and attachment for the push-off wall, eliminating the need for separate guiding profiles and reducing the number of hydraulic hoses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate guiding profiles are used for the push-off wall and sliding floor, then the device achieves reliable linear guidance, but the weight and complexity of the device increases
Solution Approach 1:
The patent combines the guiding function and structural support function into a single integrated component. The U-shaped channel profile serves both as the guiding structure for the push-off wall and as the mounting structure for the hydraulic cylinder, eliminating the need for separate guiding profiles and reducing overall device weight and complexity.
Solution Approach 2:
The U-shaped channel profile performs multiple functions simultaneously: it provides linear guidance for the push-off wall, serves as a structural support element, and acts as a mounting bracket for the hydraulic cylinder arrangement. This multi-functionality reduces the number of separate components needed in the system.
2Reliability
If multiple hydraulic hoses are used to connect both hydraulic arrangements, then each component receives adequate hydraulic supply, but the number of parts and manufacturing effort increases
Solution Approach 1:
The patent combines multiple hydraulic connections into a single integrated hydraulic cylinder unit. The first and second hydraulic cylinder arrangements are merged into one compact assembly that provides both hydraulic functions through shared mounting and fluid connections, reducing the number of separate hoses and connections required.
3Ease of operation
If a threaded spindle and sliding carriage arrangement is used for the push-off wall, then smooth relative movement is achieved, but the device complexity and number of parts increases
Solution Approach 1:
The patent merges the guiding function and movement function into a single integrated system. The U-shaped channel profile with its integrated hydraulic cylinder mounting provides both the guidance track and the actuation mechanism, eliminating the need for separate threaded spindles and sliding carriage components.
Solution Approach 2:
The patent uses a hydraulic cylinder arrangement to provide the actuating force for moving the push-off wall. The hydraulic system directly drives the movement through the integrated U-shaped channel profile, replacing complex mechanical transmission elements like threaded spindles with a more compact hydraulic actuation system.

Function Achieved in This Case
This configuration simplifies the setup, reduces weight and manufacturing effort, and enhances the device's aesthetics by minimizing parts and hoses, while allowing efficient movement of the push-off wall between loading and unloading positions.
Implementation Method 1
The push-off wall is displaceable in longitudinal direction of the loading space by means of a hydraulic cylinder piston arrangement which comprises a hydraulic cylinder piston that is movable in a hydraulic cylinder tube
Implementation Method 2
The push-off wall is mounted by means of sliding elements on the U-shaped channel profile in the manner of a sliding carriage
