Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional lighting systems are installed for retrofit applications, then lighting coverage is achieved, but wiring and power expenses increase significantly

Engineering Contradiction:

Improveinstallation costVSAvoidpower expense

Core Design Contradiction:

Ease of manufactureVSUse of energy by moving object

Solution Approach 1:

The lighting system is divided into modular fixtures that can be independently installed and configured. Each fixture operates as a discrete unit with its own power management, allowing selective installation in specific areas rather than requiring complete system-wide wiring renovations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lighting fixtures incorporate integrated power management and control capabilities, enabling them to autonomously regulate their power consumption based on environmental conditions and operational requirements, thereby reducing overall power expenses without requiring extensive external control infrastructure.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If conventional lighting systems are deployed, then basic illumination is provided, but adaptability to different environments and electricity pricing models is limited

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidsystem configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lighting system incorporates dynamic control capabilities that allow real-time adjustment of illumination parameters based on environmental conditions, occupancy detection, and electricity pricing signals. This enables the system to adapt to varying environmental requirements without requiring complex manual reconfiguration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The lighting fixtures are designed with multi-functional capabilities including illumination, occupancy sensing, ambient light detection, and communication interfaces. This universal design allows the same fixture type to serve multiple functions across diverse environments, reducing the need for specialized configurations for different applications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If modular lighting systems with sensors and network integration are implemented, then intelligent management based on energy demand is achieved, but device complexity increases

Engineering Contradiction:

Improveenergy management efficiencyVSAvoidsystem integration

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Multiple functional components including sensors, communication modules, power management circuits, and control logic are integrated into unified fixture assemblies. This consolidation reduces the number of separate components and connections required, thereby managing complexity while maintaining intelligent energy management capabilities.

Inventive Principle:

Principle #5Merging (Combining)
