Coffee Bean Roaster Internal Airflow and Chamber Partitioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee bean roasters occupy large spaces due to exposed exhaust and cooling ducts, which hinders miniaturization and aesthetics, and poses tripping hazards.
Innovation Solution
A coffee bean roaster design that partitions the casing into multiple chambers, utilizing a fan module to direct airflow internally and manage heat, eliminating the need for external ducts, with a roasting drum and heating device positioned within the machine body to facilitate efficient heat management and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If exhaust duct and cooling exhaust duct are disposed outside the machine base, then heat discharge function is achieved, but the coffee bean roaster occupies large space and aesthetics are compromised
Solution Approach 1:
The patent combines the exhaust duct and cooling exhaust duct functions into a single integrated duct structure that passes through the machine base. This merging of functions eliminates the need for separate external ducts, reducing the overall space required while maintaining both heat discharge and cooling capabilities.
Solution Approach 2:
The exhaust duct is designed to pass through the machine base structure, nesting the duct pathway within the existing machine framework rather than requiring external space. This allows the duct system to be embedded within the machine's structural volume, reducing the footprint.
2Temperature
If exhaust duct and cooling exhaust duct are disposed outside the machine base, then heat discharge function is achieved, but aesthetics are compromised and tripping hazards are created
Solution Approach 1:
The duct system is extracted from the external environment and repositioned to pass through the machine base internally. This removes the visible external ducts that cause aesthetic issues and tripping hazards, while the functional capability to discharge heat and provide cooling is preserved through the internal pathway.
Solution Approach 2:
The machine base is designed with an opening or passage that allows the duct to pass through, creating an integrated structure where the duct becomes part of the machine base rather than an external attachment. This integration eliminates visual clutter and physical trip hazards while maintaining functionality.
3Temperature
If multiple ducts are exposed outside the machine base, then heat management is achieved, but device complexity increases
Solution Approach 1:
The patent merges the exhaust duct and cooling exhaust duct into a single integrated duct structure. This consolidation reduces the number of separate components, simplifies the overall system configuration, and reduces installation and maintenance complexity while maintaining both heat discharge and cooling functions.
