Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a complicated overall structure with numerous parts and components is used, then automation level is improved, but device complexity increases and service life decreases
Solution Approach 1:
The patent combines multiple functions into integrated components. The brewing mechanism integrates the brewing head, drive parts, and large gear into a unified assembly. The coffee box mechanism merges the coffee box, residue ejecting mechanism, and resetting mechanism into a coordinated system. This merging reduces the number of separate components while maintaining full automation capabilities.
Solution Approach 2:
The drive component serves multiple functions: it drives the brewing mechanism, controls the coffee box mechanism, and coordinates the water feeding and discharging mechanism. The large gear both drives the brewing head and engages with the drive component. This multi-functionality reduces the need for separate dedicated components for each function.
2Extent of automation
If numerous parts and components are used, then automation level is improved, but ease of repair worsens
Solution Approach 1:
The device is divided into distinct modular mechanisms: the brewing mechanism, coffee box mechanism, and water feeding and discharging mechanism. Each mechanism can be accessed and repaired independently. The brewing mechanism can be serviced separately from the coffee box mechanism, and the water feeding mechanism is accessible through the side opening.
Solution Approach 2:
The residue ejecting mechanism and resetting mechanism are extracted as separate functional units within the coffee box mechanism. The residue ejecting rod can be removed and cleaned independently. The water distribution plate component can be extracted for separate cleaning and maintenance without disassembling the entire device.
3Manufacturing precision
If a complicated water feeding structure is used, then brewing precision is improved, but device complexity increases
Solution Approach 1:
The water feeding and discharging mechanism uses a stepping motor to control water flow through a water feeding switch. The water is delivered through a simplified water way system with a coffee box water inlet and outlet. This hydraulic control system achieves precise water delivery without requiring complex mechanical feeding structures.
4Extent of automation
If numerous mechanical parts are used, then automation level is improved, but service life decreases
Solution Approach 1:
The patent replaces purely mechanical drive systems with a combination of electromagnetic and hydraulic control. The stepping motor provides precise control with fewer mechanical wear points compared to traditional mechanical cams and linkages. The water feeding switch uses electromagnetic control rather than mechanical valves, reducing wear and extending service life.

AI summary
Disclosed is a coffee brewing device, comprising a coffee box, brewing mechanism, water feeding and discharging mechanism and main body bracket. The coffee box is inside the lower end of the main body bracket; the brewing mechanism at the upper end. The coffee box mechanism is connected to the brewing mechanism, with water feeding and discharging mechanism on one side of the main body bracket, connected to a water way of the coffee box mechanism. The main body bracket has a coffee inlet, a drive component for driving and connecting the brewing mechanism, a first assembling hole for installing one end of the coffee box mechanism, and a second moving guide groove for movably installing the other end of the coffee box mechanism. The coffee brewing device has accurate drive control, simple water feed, quiet, quick, stable, no dismantling or washing, long service life, reliable, and few mechanical parts.
