Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for crushing and discharging granular clump material from flexible containers, such as those described in Patent Document 1, face challenges in achieving effective crushing and complete discharge due to the retention of container shape after compaction, difficulty in handling non-crushed material, and inefficiency with rectangular containers where material remains in corners.
Innovation Solution
A method and device involving a hanger for flexible containers with a discharge tube, pairs of symmetrically swingable contact units that thrust and press against the container to crack and disintegrate the material, ensuring nearly complete discharge through a central discharge tube by repetitive thrusting and pressing actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the flexible container is compacted and solidified for effective transport and storage, then the granular clump material is efficiently packed, but the material cannot be taken out through the discharge tube and requires crushing
Solution Approach 1:
The container bottom is segmented into a central discharge tube region and peripheral compression regions. The compression device applies force to the peripheral regions while the central region remains open for discharge, enabling the material to be crushed and simultaneously discharged through the segmented structure
Solution Approach 2:
A compression device is introduced as an intermediary mechanism between the compacted material and the discharge tube. This device applies localized compression forces to break up the solidified material into crushable pieces that can then be discharged through the tube
2Productivity
If a planar plate is used to crush the granular clump material by thrusting against the container, then crushing operation is initiated, but the container shape is retained after compaction making further crushing ineffective
Solution Approach 1:
Instead of applying uniform compression across the entire container bottom, the compression device applies localized compression forces specifically to peripheral regions adjacent to the discharge tube. This localized approach allows material in these regions to be broken up while the overall container shape is maintained for structural integrity
Solution Approach 2:
The compression device is designed to be movable and adjustable, allowing it to dynamically adapt its position and compression force. This enables the device to effectively crush material in different regions of the container bottom while maintaining flexibility in operation
3Quantity of substance
If the flexible container is of rectangular shape, then storage efficiency is improved, but crushed material remaining in the four corners cannot be easily discharged through the bottom opening
Solution Approach 1:
The compression device acts as an intermediary that actively pushes material from corner regions toward the central discharge tube. By applying compression forces to peripheral and corner regions, it facilitates the movement of trapped material into the discharge path
Solution Approach 2:
The compression device introduces a new dimensional approach by applying forces from the container bottom upward and from peripheral regions inward toward the center. This multi-directional compression approach enables material in corner regions to be pushed toward the central discharge tube for complete discharge

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively disintegrates and discharges granular clump material from flexible containers, ensuring nearly complete removal by utilizing the gravity flow through the central discharge tube and peripheral squeezing actions, addressing the limitations of previous technologies.
Implementation Method 1
thrusting top portions of contact units against a bottom wall of the flexible container... pressing side portions of the contact units onto portions of the flexible container
Implementation Method 2

AI summary
The device and method for crushing and discharging a granular clump material in a flexible container includes a hanging step for hanging from above a flexible container containing a compacted granular clump material, a thrusting step for thrusting top portions of contact units against a bottom wall of the flexible container in regions on opposite sides of a discharge tube extending downward from a central region of the bottom wall, and a pushing step for pushing side portions of the contact units in regions from the bottom wall to side portions of the flexible container. The method and device are capable of crushing the granular clump material in the flexible container and of discharging substantially whole amount thereof.
