Solution Overview

Problem

Small-scale malting plants face challenges with high investment costs and incorrectly chosen dimensions due to fluctuating demand, limiting their ability to expand without significant peripheral equipment changes.

Innovation Solution

A modular and compact malting plant design that allows adjustable batch sizes by connecting a heating building to germination drying units via ducts, using a central drying fan and heat exchanger, and enabling expansion through removable modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-size malting plant is installed, then initial investment is made, but the plant cannot adapt to fluctuating demand and may have incorrectly chosen dimensions

Engineering Contradiction:
Improveadaptability to demand fluctuationsVSAvoidplant configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The malting plant is divided into modular germination drying units that can be independently connected or disconnected from the heating building. Each unit is a self-contained module with standardized interfaces, allowing the system to be configured in different sizes (16t, 24t, 32t, 40t, 48t, 56t batch capacity) by simply adding or removing modules without redesigning the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The plant configuration is made dynamically adjustable through removable germination drying units that can be connected via standardized duct interfaces. The system transitions from a static fixed-size design to a dynamic reconfigurable system where capacity can be changed by connecting or disconnecting modules, enabling adaptation to varying production demands.

Inventive Principle:
Principle #15Dynamics

2Productivity

If the plant is expanded to increase capacity, then production capacity increases, but peripheral equipment must be significantly changed

Engineering Contradiction:
Improvebatch capacityVSAvoidexpansion difficulty
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The plant is segmented into standardized germination drying units with uniform dimensions and connection interfaces. To expand capacity from 16t to 32t or 56t batch, identical modular units are simply added in series, connected through standardized air duct interfaces, eliminating the need to redesign or replace existing peripheral equipment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heating building and air handling equipment are designed with universal capacity to serve multiple germination drying units of the same model. A single heating building can support different numbers of germination drying units (1-7 units), making the peripheral equipment multi-functional and eliminating the need for separate equipment for each capacity level.

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

3Adaptability or versatility

If a larger plant is installed to cover future demand, then future capacity is secured, but investment costs increase and resource use is optimized only at higher volumes

Engineering Contradiction:
Improvefuture demand coverageVSAvoidinvestment resources
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The plant capacity is segmented into discrete modular units that can be acquired incrementally. Instead of investing in a large 56t plant immediately, the customer can start with one 16t unit and add three more units as demand grows, spreading investment over time and matching resource expenditure with actual production needs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows installing exactly the plant size needed for current demand (partial action) rather than over-building for future possibilities. The modular design enables starting with minimal capacity and adding units only when demand justifies the expansion, avoiding excessive investment in unused capacity.

Inventive Principle:
Principle #16Partial or excessive action

4Adaptability or versatility

If modular design is implemented for flexibility, then capacity can be adjusted, but system complexity increases

Engineering Contradiction:
Improvecapacity adjustabilityVSAvoidmodular system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is segmented into standardized modules with uniform connection interfaces and dimensions. This segmentation creates apparent complexity in module数量配置 but simplifies the actual connection process, as each module connects identically to the heating building and to each other, reducing operational complexity despite increased configurability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system maintains constant physical parameters (module dimensions, connection interface specifications, air flow rates) while changing only the number of modules. This parameter standardization allows capacity adjustment through quantity changes rather than design changes, reducing the complexity of modular integration despite increased adaptability.

Inventive Principle:
Principle #35Parameter changes
