Solution Overview

Problem

Hydraulic systems often require additional piping and increased construction costs to accommodate pressure boosters, and existing systems lack efficient pressure management, leading to unnecessary energy consumption and operational limitations.

Innovation Solution

A hydraulic system with a booster module integrated into the valve block, featuring a pressure booster that can be activated or inactivated as needed, using hydraulic or electrically operated inactivating means to supply pressure on demand, allowing for efficient pressure management and reduced energy usage by only delivering higher pressure when required.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a pressure booster is integrated into the valve block, then the system construction is simplified and additional piping is eliminated, but the device complexity increases due to the integration of multiple modules

Engineering Contradiction:
Improvesystem constructionVSAvoidmodule integration
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The booster module is integrated directly into the valve block, merging the pressure boosting function with the valve control system. This eliminates the need for separate piping connections between the booster and valve modules, simplifying the overall system construction while managing complexity through functional integration

Inventive Principle:
Principle #5Merging (Combining)

2Use of energy by moving object

If the pressure booster is activated only when required, then energy consumption is reduced, but the system control complexity increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidpressure management
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The system dynamically activates or deactivates the pressure booster based on real-time pressure requirements. The inactivating means respond to pressure conditions, automatically switching the booster on or off to maintain optimal pressure levels while minimizing energy consumption, thus balancing energy efficiency with control complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational state of the pressure booster based on pressure parameters. When pressure exceeds a certain threshold, the inactivating means deactivate the booster; when pressure drops below the threshold, the booster is reactivated. This parameter-based control optimizes energy usage while managing system complexity through clear activation criteria

Inventive Principle:
Principle #35Parameter changes

3Stress or pressure

If the valve block is dimensioned to withstand higher pressure, then the system can handle boosted pressure, but the weight and size of the valve block increase

Engineering Contradiction:
Improvepressure toleranceVSAvoidvalve block weight
Core Design Contradiction:
Stress or pressureVSWeight of moving object

Solution Approach 1:

The valve block is designed with localized reinforcement only in the areas where high pressure is applied, rather than uniformly strengthening the entire block. This allows the valve block to withstand boosted pressure from the integrated booster module while minimizing unnecessary weight and material usage in areas not subjected to high stress

Inventive Principle:
Principle #3Local quality
