Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing electrical connector designs are used, then current interrupting functionality is provided, but the device is cumbersome and lacks self-powering capabilities

Engineering Contradiction:
Improvemanual installation and operationVSAvoidconnector structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single integrated connector device: current interruption capability, self-powering through energy harvesting from the current path, and control apparatus for resetting the circuit. This integration eliminates the need for separate external power sources and control systems, making the device compact and easy to operate manually while maintaining full functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector is designed to harvest electrical energy from the current path itself to power its control apparatus and resetting mechanisms. This self-powering capability eliminates dependence on external power sources, allowing the device to autonomously reset after current interruption and simplifying installation and operation without requiring additional infrastructure.

Inventive Principle:
Principle #25Self-service

2Productivity

If compact design is implemented, then installation efficiency is improved, but space for switching apparatus and control components is reduced

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidhousing space
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The patent employs a nested arrangement where the control apparatus, switching apparatus, and power harvesting components are positioned within compartments and sections of the housing that optimize space utilization. The mechanical interface, current path, and control elements are arranged in a compact configuration where smaller components are embedded within or adjacent to larger structural elements, achieving a compact overall volume while accommodating all necessary functional elements.

Inventive Principle:
Principle #7Nested doll (Nesting)
