Solution Overview
Problem
Existing coffee brewing devices have limited movement trajectories for the coffee box assembly, restricting its ability to move directionally and perform tasks such as adding coffee powder, brewing, pushing out residues, and scraping residues effectively.
Innovation Solution
A coffee brewing device with a body fixing frame assembly featuring multiple segment movement trajectories on both sides, allowing the powder box assembly to move directionally and swing to various positions for powder addition, brewing, residue removal, and scraping, utilizing a screw assembly and supporting frames to drive these movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a screw assembly is used to drive a coffee box assembly to move, then the coffee box assembly can be driven to move along a one-segment linear or annular movement trajectory, but the movement trajectory is relatively single and lacks direction variability
Solution Approach 1:
The movement trajectory is divided into multiple segments (first movement trajectory and second movement trajectory) with different movement directions. The coffee box assembly moves along the first trajectory for powder addition and along the second trajectory for residue removal, enabling direction-variable movement through trajectory segmentation rather than requiring a single complex trajectory structure.
Solution Approach 2:
The system transitions from static fixed trajectories to dynamic adaptable trajectories. The screw assembly can switch between driving the coffee box along different trajectories based on operational requirements, making the movement path flexible and adaptable to different functional states (powder addition, brewing, residue removal).
2Productivity
If the coffee box assembly is limited to one-segment linear or annular movement, then the device structure is simple, but it cannot efficiently perform multiple tasks such as adding coffee powder, brewing, pushing out residues, and scraping residues
Solution Approach 1:
The coffee box assembly is designed to perform multiple functions by moving along different trajectories: powder addition (first trajectory), brewing (first trajectory), residue pushing out (second trajectory), and residue scraping (second trajectory). This multi-functionality is achieved through the universal design of the coffee box that can adapt to different operational modes without requiring separate mechanisms for each function.
Solution Approach 2:
The system adds the dimension of trajectory selection to the traditional single-path movement. By introducing the concept of multiple trajectory segments with different spatial orientations and functions, the system transforms from a one-dimensional movement path to a multi-dimensional trajectory system, enabling efficient performance of multiple tasks.
3Adaptability or versatility
If separate independent structures or integral structure is used for left and right body fixing frames, then the frames can jointly realize direction-variable movement, but the structural design becomes complex
Solution Approach 1:
The left and right body fixing frames are designed with asymmetric trajectory configurations - the left frame has a first movement trajectory while the right frame has a second movement trajectory. This asymmetric design allows each frame to specialize in specific movement functions, enabling direction-variable movement capability while maintaining clear functional differentiation that simplifies the overall control logic.
