Movable Inner Container Shaker for Lump-Free Granular Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scattering devices with moving inner containers are ineffective for dispensing granular materials like flour and spices, as they form lumps and are difficult to dose, and the complex mechanisms used in alternative devices are hard to clean and prone to failure.
Innovation Solution
A scattering device with an outer container and an inner container that uses a force accumulator to move transversely over a sieve, allowing easy operation and cleaning, where the inner container is pressed against the outer container's side wall by a force accumulator, enabling the material to trickle out through a discharge opening over the sieve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a moving conveying element is used to move particles over a sieve, then the granular material can be effectively dispersed, but the mechanism becomes complex and difficult to clean
Solution Approach 1:
The patent extracts the complex conveying mechanism from the system and replaces it with a simple manual shaking motion. The inner container is removed from fixed mounting and made movable by simply holding the outer container, eliminating motors, belts, and complex drive mechanisms while maintaining the particle dispersion function through direct user action.
Solution Approach 2:
The device uses the user's hand as the driving mechanism - by gripping the outer container, the user's fingers directly move the inner container back and forth over the sieve. This self-service approach eliminates the need for separate motorized conveying elements, making the system both simpler and easier to clean since there are no hidden mechanical components.
2Productivity
If the inner container is fixed in position, then the structure is simple, but the granular material cannot be effectively dispersed
Solution Approach 1:
The patent transforms the static inner container into a dynamic one by allowing it to move freely within the outer container. The inner container is not fixed but is instead positioned to be movable when the outer container is gripped, enabling the necessary back-and-forth motion for effective material dispersion while keeping the structural complexity minimal.
3Productivity
If the inner container is movable within the outer container, then the granular material can be dispersed, but the mechanism becomes complex and hard to clean
Solution Approach 1:
The patent segments the device into two separate containers - an outer container held by the user and an inner container that moves within it. This segmentation allows the inner container to be easily removed and cleaned separately, while the outer container remains simple and accessible. The movable interface between containers enables dispersion without creating hard-to-reach mechanical joints.

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 device allows for easy and efficient dispensing of granular materials by moving the inner container over a sieve, breaking up lumps and ensuring easy cleaning and maintenance, with components that can be produced inexpensively and assembled quickly for immediate operation.
Implementation Method 1
at least one energy store arranged in the intermediate space, so that the inner container in its rest position is pressed with the first section of its side wall against the opening in the side wall of the outer container by at least one force accumulator

AI summary
The present invention relates to a spreading device (2) with an outer container (4) and an inner container (6) movable therein for dispensing a granular or powdery spreading material from a storage space (36) formed in the inner container (6) through a discharge opening the scattering device (2) arranged sieve. In order to create a spreading device that has a drive for the screening device that is easy to operate and easy to clean, the side wall (8) of the outer container (4) has an opening (12) in one area, through which a first section of the side wall (10) of the inner container (6) when grasping around the outer container (4), inside the outer container (4) there is an intermediate space (22), the inner container (6) is held in its rest position by at least one energy accumulator (24 ) is pressed against the opening (12) in the side wall (8) of the outer container (4), the inner container (6) is moved against the force of the at least one energy accumulator (24) transversely to the longitudinal axis (14) of the outer container (4) into a displacement position movable, and the inner container (6) has a discharge opening (32) which, during a displacement movement of the inner container (6) from the rest position into a displacement position, opens over a sieve located in the bottom of the outer container (4). (34) is moved with an associated discharge port (30).
