Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic systems for grouping fragile floating objects, such as fruits and vegetables, face limitations in achieving efficient multi-layer superposition without causing turbulence, deterioration, or overflowing, and require longer channel lengths.
Innovation Solution
A method and device that utilize a movable cross-sectional restriction, or 'jump,' within the accumulation channel to locally accelerate the hydraulic current, allowing for progressive and homogeneous superposition of objects across multiple layers by moving the restriction upstream, thereby reducing channel length and enhancing production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fixed cross-sectional restriction is used to accelerate hydraulic current for object superposition, then local acceleration is achieved, but the number of superposed layers is limited to two layers
Solution Approach 1:
The cross-sectional restriction is made movable along the accumulation channel instead of being fixed. This dynamic element can be positioned at different locations to progressively accelerate objects into multiple superposed layers, transforming the system from static two-layer capability to dynamic multi-layer capability
Solution Approach 2:
The movable cross-sectional restriction is positioned upstream before objects arrive, creating acceleration zones in advance. This preliminary positioning allows objects to be progressively accelerated into designated superposition layers before reaching the discharge end, enabling controlled multi-layer formation
2Reliability
If longer accumulation channels are used to allow natural hydraulic superposition, then object integrity is maintained, but the installation surface area increases
Solution Approach 1:
The invention uses hydraulic current acceleration through movable cross-sectional restrictions to create superposition zones. This hydraulic mechanism replaces the need for long natural accumulation channels, achieving multi-layer superposition in a compact space while maintaining gentle object handling through controlled hydraulic flow
Solution Approach 2:
The dynamic positioning of cross-sectional restrictions creates progressive acceleration zones that efficiently pack objects into multiple layers within a shortened channel length, reducing the overall installation footprint while maintaining object integrity through controlled hydraulic forces
3Productivity
If higher hydraulic flow rates are used to achieve multi-layer superposition, then superposition efficiency is improved, but object deterioration and turbulence increase
Solution Approach 1:
Hydraulic acceleration is applied locally at specific positions along the accumulation channel through movable cross-sectional restrictions, rather than uniformly throughout. This localized acceleration creates efficient superposition zones while maintaining gentler flow conditions in other areas, preventing object deterioration
Solution Approach 2:
The movable cross-sectional restrictions dynamically create and move acceleration zones through the channel, concentrating hydraulic energy only where and when needed for superposition. This dynamic approach achieves high superposition efficiency while minimizing turbulent effects and object damage through precise spatial and temporal control

Implementation Method 1
any object having sufficient buoyancy in a current of liquid to be able to be transported by the latter
Implementation Method 2
hydraulic current capable of transporting the objects
Implementation Method 3

AI summary
The invention relates to a method and a device for grouping fragile floating objects such as floating fruit into batches, in at least one accumulation channel with hydraulic superimposition of the retained objects in a superimposition zone against a retaining/releasing device which is closed so as to retain the articles. During a step of accumulating articles in an accumulation channel (11), a jump (17) towards the top of the bottom (19) of the accumulation channel (11) is moved upstream into said superimposition zone (18) from the downstream end (13) of the accumulation channel (11), as the articles are supplied, in such a way as to cause a superimposition of the articles retained in the superimposition zone between said jump (17) and the retaining/releasing device (14).
