Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If building control systems use traditional fixed installations, then system stability is maintained, but accessibility and ease of configuration deteriorate

Engineering Contradiction:
Improvecomponent accessibilityVSAvoidsystem configuration stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The building control system is divided into modular components (control modules, transformers, relays) that can be independently accessed and configured. Each component is mounted on removable panels that can be slid out of the rack, allowing individual access without disturbing the entire system configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates slidable panels with slides that enable dynamic access to components. The panels can be positioned at different locations along the slides, allowing flexible configuration and maintenance access while maintaining system stability when closed.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If building control systems integrate multiple components, then functionality is improved, but device complexity increases

Engineering Contradiction:
Improvesystem functionalityVSAvoidwiring complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple building control components (control modules, transformers, relays) are integrated into a single rack system with unified wiring infrastructure. The terminal panel provides centralized connection points that simplify wiring by consolidating multiple connections into organized access points.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rack system is designed as a universal platform that can accommodate various types of building control components. The standardized mounting panels and terminal connections allow different components to be integrated using the same infrastructure, reducing overall system complexity.

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

3Adaptability or versatility

If building control systems use modular components, then adaptability is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveconfiguration flexibilityVSAvoidcomponent mounting precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system uses standardized modular panels with consistent mounting interfaces. Each panel is designed with uniform dimensions and mounting hole patterns, allowing components to be mounted with standard tolerances while maintaining overall system precision through modular assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The slidable panels are designed to engage with the rack at standardized positions along the slides, creating equipotential mounting locations. This ensures that components mounted on different panels maintain consistent spatial relationships without requiring high-precision individual mounting.

Inventive Principle:
Principle #12Equipotentiality

4Productivity

If building control systems are installed traditionally, then installation stability is maintained, but productivity deteriorates

Engineering Contradiction:
Improvedeployment speedVSAvoidtesting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system incorporates a terminal panel with pre-organized connection terminals that are wired in advance during manufacturing. This preliminary wiring organization eliminates the need for time-consuming field wiring and testing, allowing faster deployment while maintaining installation stability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal panel serves as an intermediary between the internal rack components and external building systems. By consolidating all connections at this single interface, the system reduces the time required for installation and testing while maintaining the stability of internal component connections.

Inventive Principle:
Principle #24Intermediary (Mediator)
