Solution Overview

Problem

Existing ultra-high pressure press systems are not compact enough and suffer from hydraulic fluid losses, necessitating a more efficient and space-saving design for generating ultra-high pressures of at least 1 GPa.

Innovation Solution

A cubic press system with a cartridge assembly featuring an electro-mechanical drive mechanism using a servomotor and threaded beams to reciprocate an intensifier rod within a housing, minimizing space requirements and reducing hydraulic fluid losses by eliminating the need for extensive tubing and seals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a traditional hydraulic press system is used, then ultra-high pressure can be generated, but the system occupies large space and suffers from hydraulic fluid losses

Engineering Contradiction:
Improvesystem volumeVSAvoidhydraulic fluid loss
Core Design Contradiction:
Volume of moving objectVSLoss of energy

Solution Approach 1:

The patent extracts and eliminates the hydraulic fluid transmission system (tubing, seals, reservoirs) from the press system. By directly coupling the servo motor to the intensifier rod through a threaded beam mechanism, the system removes the intermediary hydraulic fluid pathway, thereby eliminating fluid losses while reducing overall system volume.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the hydraulic transmission system with a direct electro-mechanical drive system. The servo motor converts electrical energy to mechanical motion, which is then transmitted through a threaded beam to the intensifier rod, eliminating the need for hydraulic fluid and associated loss-prone components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Volume of moving object

If a compact cartridge design is implemented, then space requirements are reduced, but manufacturing complexity increases

Engineering Contradiction:
Improvecartridge volumeVSAvoidmanufacturing complexity
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The patent employs a nested cartridge assembly where the intensifier rod, piston, chamber, and drive mechanism are concentrically arranged within a single cylindrical housing. This nested configuration achieves compactness while using standardized cylindrical components that are relatively straightforward to manufacture and assemble.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The cartridge assembly is designed as a self-contained module that integrates multiple functions: the housing serves as both structural support and fluid containment, the threaded beam provides both motion transmission and positioning, and the intensifier rod performs both actuation and sealing functions. This multi-functionality reduces the number of separate components needed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A cartridge assembly comprising a chamber for containing hydraulic fluid, an intensifier element capable of reciprocating in the chamber and displacing the hydraulic fluid responsive to a drive means acting on the intensifier element, and a piston capable of reciprocating in the chamber and being displaceable responsive to a change in the pressure of the hydraulic fluid. The cartridge assembly is configured so that when the pressure in the fluid increases responsive to a first force being applied by the drive means on the intensifier, the hydraulic fluid will exert a second force on the piston, the second force being greater than the first force; the mass of the hydraulic fluid being substantially conserved within the cartridge assembly.
