Solution Overview

Problem

Existing coffee brewing devices have limited movement trajectories for the coffee box assembly, resulting in single-directional and inefficient operations such as adding coffee powder, brewing, pushing out residues, and scraping residues.

Innovation Solution

A coffee brewing device with a body fixing frame assembly featuring left and right body fixing frames, each with multi-segment direction-variable movement trajectories, allowing the powder box assembly to swing and move to various positions for adding coffee powder, brewing, pushing out residues, and scraping residues, utilizing a screw assembly for coordinated movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single-segment linear or annular movement trajectory is used for the coffee box assembly, then the device structure is simple, but the movement trajectory is single and operational efficiency is limited

Engineering Contradiction:
Improveoperational efficiencyVSAvoidmovement trajectory structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The movement trajectory is divided into multiple segments (first movement trajectory and second movement trajectory) with different functional zones. Each segment handles specific operations such as adding coffee powder, brewing, pushing out residues, and scraping residues, allowing the coffee box assembly to follow optimized paths for each operation type thereby improving overall operational efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces multi-directional movement by providing both first and second movement trajectories that operate in different spatial dimensions and directions. This enables the coffee box assembly to swing to different positions and access various functional areas, transforming the single-directional movement into multi-dimensional operation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the body fixing frame is designed as an integral structure, then manufacturing is simpler, but flexibility in implementing multi-directional movement is reduced

Engineering Contradiction:
Improvemulti-directional operation capabilityVSAvoidframe structure fabrication
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The body fixing frame is divided into left and right separate frames, each independently providing movement trajectories. This segmentation allows each frame to be manufactured and adjusted independently, facilitating the implementation of complex multi-directional movement while maintaining manufacturing simplicity through modular construction

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The body fixing frame incorporates movable components and adjustable mechanisms that allow the frame structure to dynamically adapt to different operational requirements. This enables multi-directional movement capability while maintaining structural integrity and ease of assembly

Inventive Principle:
Principle #15Dynamics
