Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If solar cells are independently provided and connected with additional cable connections, then power supply functionality is achieved, but device complexity and installation difficulty increase

Engineering Contradiction:
Improvepower supply functionalityVSAvoidarrangement complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent integrates the solar cell directly into the housing structure, merging the power supply component with the main body. The solar cell is positioned to extend through the housing with its light-receiving surface exposed, eliminating the need for separate cable connections while maintaining power supply functionality.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If solar cells are integrally provided with the irrigation controller body, then installation simplicity is improved, but installation flexibility and setup possibilities are limited

Engineering Contradiction:
Improveinstallation simplicityVSAvoidinstallation flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The housing is divided into multiple sections with the solar cell positioned in a specific region that extends through the housing. This segmentation allows the solar cell to be integrated into the structure while maintaining exposure to light, enabling both simplified installation and flexibility for various mounting positions including wall-mounted and hanging configurations.

Inventive Principle:
Principle #1Segmentation

3Volume of moving object

If the irrigation controller is designed for compact integration, then space efficiency is improved, but access to components for maintenance becomes difficult

Engineering Contradiction:
Improvecontroller compactnessVSAvoidcomponent accessibility
Core Design Contradiction:
Volume of moving objectVSEase of repair

Solution Approach 1:

The housing structure is designed to provide multiple functions: it encloses internal components for compact integration while simultaneously providing access points and mounting features. The solar cell's extended position and the housing's structural design allow maintenance access without requiring disassembly, achieving both compactness and ease of repair.

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