Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems for bulk solid products are inefficient for large quantities, tedious to use, and lack hygienic filling capabilities, with complex and costly mechanical designs that restrict aesthetic and functional adaptability.
Innovation Solution
A dispensing device with a rotary shutter and handle that allows easy replacement of containers, adjustable flow rate, and inclined separators to prevent blocking, enabling gravity-fed dispensing without turning the container, and a modular design for adapting to different products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an Archimedes screw or wheel with paddles is used for dispensing, then blocking risk is reduced, but the device becomes tedious to operate for large quantities
Solution Approach 1:
The shutter is divided into multiple parts (first part with handle, second part with openings) that can rotate independently relative to each other. This segmentation allows the product to flow through multiple openings simultaneously, reducing blocking risk while maintaining easy operation through a simple handle rotation mechanism.
Solution Approach 2:
The invention transitions from linear/vertical dispensing mechanisms (Archimedes screw, wheel with paddles) to a rotary shutter mechanism where the mobile part rotates about a vertical axis. This dimensional change allows gravity to naturally guide the product through multiple openings in the shutter, reducing both blocking risk and operational effort.
2Stability of the object's composition
If the container is fixed to a wall support, then stability is improved, but aesthetic possibilities are limited
Solution Approach 1:
The dispensing device is separated into a removable container and a fixed dispensing unit with the shutter mechanism. The container can be detached and replaced easily, allowing for various container shapes and designs while the dispensing unit remains stable and fixed to the support structure.
Solution Approach 2:
The container is designed with dynamic characteristics - it can be easily attached and detached from the dispensing device. This dynamic connection allows the container to be replaced with different designs or removed entirely, providing aesthetic flexibility while maintaining stability during the dispensing operation.
3Ease of operation
If the container rests on an inclined plane, then dispensing is facilitated, but the device becomes bulky and unaesthetic
Solution Approach 1:
The container is designed to rest vertically on the support structure without requiring an inclined plane. The shutter mechanism is positioned at the bottom of the container, allowing gravity to naturally guide the product through the shutter openings and out of the dispensing device, eliminating the need for bulky inclined structures.
Solution Approach 2:
Instead of using an inclined plane (two-dimensional solution), the invention uses a vertically oriented shutter mechanism at the bottom of the container. The rotary shutter with multiple openings allows product flow in the vertical dimension, eliminating the need for horizontal inclination and reducing overall device bulk.
4Measurement precision
If a diaphragm shutter is used for individual use, then precision is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The shutter is segmented into multiple parts (first part with handle, second part with openings) that can be manufactured separately using simple processes. This segmentation allows each part to be produced independently with standard manufacturing techniques, reducing overall manufacturing complexity and cost while maintaining dispensing precision through the coordinated operation of the segmented parts.
Solution Approach 2:
Instead of using a complex diaphragm shutter mechanism, the invention inverts the approach by using a simple rotary shutter with multiple openings. The precision is achieved not through complex mechanical deformation (diaphragm) but through the geometric arrangement of multiple openings in the rotary shutter, simplifying the manufacturing process.
5Quantity of substance
If the container is turned over to dispense, then dosing is achieved, but the device is unsuitable for store use
Solution Approach 1:
The shutter is divided into multiple parts with multiple openings, allowing the product to be dispensed through several openings simultaneously. This segmentation enables large quantities to be dispensed efficiently without turning the container, making the device suitable for store use while maintaining dose control through the shutter opening mechanism.
Solution Approach 2:
The invention transitions from horizontal dispensing (requiring container inversion) to vertical dispensing through a bottom-mounted rotary shutter. The mobile part rotates about a vertical axis, allowing gravity to guide the product through the shutter openings and out of the dispensing device in a vertical direction, eliminating the need to turn the container over.
