Solution Overview
Problem
Current paint mixing systems lack the ability to dynamically generate customized sizes of paint containers based on the determined amount of paint requested, leading to inefficiencies in paint usage and storage.
Innovation Solution
A paint mixing system that includes a first computing system with a database to receive color inputs, retrieve identifiers, and transmit them to a second computing system connected to a paint mixer and 3-D printer, which generates the specified amount of paint and fabricates a three-dimensional container of the appropriate size for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional fixed-size paint containers are used, then storage and handling are simplified, but paint usage efficiency deteriorates due to waste from excess capacity
Solution Approach 1:
The patent implements dynamic container sizing where the container volume is adjusted based on the actual paint quantity required for each mixing job. The system calculates the exact paint volume needed based on the color formula and batch size, then selects or configures a container of matching capacity, ensuring near-complete utilization of painted material without significant waste.
Solution Approach 2:
The system changes the container volume parameter dynamically according to the paint batch requirements. Instead of using fixed container sizes, the system varies container capacity as a function of the requested paint amount, allowing optimization of paint usage efficiency for different batch sizes from small touch-up jobs to large production batches.
2Quantity of substance
If standardized containers are used for all paint batches, then manufacturing and inventory management are simplified, but storage space utilization deteriorates due to empty space in oversized containers
Solution Approach 1:
The system dynamically matches container size to paint batch size, improving storage space utilization by minimizing empty space. The container selection or fabrication process is adjusted based on the calculated paint volume, ensuring that containers are appropriately sized for each specific application rather than using one-size-fits-all standardized containers.
3Loss of substance
If large containers are used for small paint batches, then fewer container types are needed, but paint waste increases due to unused capacity
Solution Approach 1:
The system changes container size parameters to match the actual paint batch requirements. For small batches, small containers are selected or fabricated; for large batches, larger containers are used. This parameter adaptation minimizes paint waste by ensuring the container capacity closely matches the paint quantity, eliminating the excess capacity that would lead to waste in traditional fixed-size containers.
4Productivity
If custom-sized containers are fabricated for each batch, then paint usage efficiency is optimized, but system complexity and fabrication time increase
Solution Approach 1:
The patent merges the container fabrication function (3-D printing) with the paint mixing operation into an integrated system. The 3-D printer is positioned to receive containers directly from the fabrication station, and the mixing apparatus is configured to transfer paint directly into the freshly printed containers. This consolidation of functions reduces overall system complexity despite the added capability of custom container fabrication.
Solution Approach 2:
The system performs preliminary container fabrication before the paint mixing operation begins. The 3-D printer creates the customized containers in advance, allowing them to be ready for immediate receipt of the mixed paint. This preliminary action enables the subsequent mixing and transfer operations to proceed efficiently without waiting for container preparation.
