Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial plugs lack universality, causing inconvenience when marine containers need to be powered in different configurations, as they are not adaptable to switch between 3 o'clock and 6 o'clock earthing contact positions.
Innovation Solution
An industrial plug design featuring a rotary braking pin system that allows the earthing insertion core component to switch between 3 o'clock and 6 o'clock positions by rotating the clamping block between two grooves, enabling flexible adaptation to different voltage configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the industrial plug uses a fixed earthing contact position (either 3h or 6h), then the plug meets specific voltage configuration requirements, but the plug lacks universality and cannot adapt to different power interfaces
Solution Approach 1:
The patent applies the dynamics principle by making the earthing contact position changeable rather than fixed. The rotary braking pin mechanism allows the plug to dynamically switch between 3h and 6h earthing contact positions, enabling adaptation to different voltage configurations without requiring multiple separate plugs. This dynamic adjustability directly resolves the contradiction between adaptability and structural complexity.
Solution Approach 2:
The patent implements universality by designing a single plug that can perform multiple functions - specifically, it can operate with either 3h or 6h earthing contact positions depending on the power interface requirements. The rotary braking pin system enables one plug to replace what would traditionally require two different plugs, achieving multi-functionality and broadening applicability across different marine container power systems.
2Ease of operation
If the industrial plug is designed for a specific earthing contact position, then it meets precise configuration requirements, but it causes inconvenience and requires plug replacement when moving between different power interfaces
Solution Approach 1:
The rotary braking pin mechanism provides dynamic switching capability that allows users to change earthing contact positions without replacing the entire plug. This dynamic adjustment feature eliminates the time loss associated with plug replacement and significantly improves ease of operation when moving between different power interfaces with different earthing configurations.
3Adaptability or versatility
If the plug uses a rotary braking pin mechanism with clamping blocks and grooves, then it achieves flexible switching between positions, but the device complexity increases
Solution Approach 1:
The rotary braking pin mechanism is segmented into distinct functional components: the rotary braking pin itself, the clamping blocks, the first and second grooves, and the compression spring. This segmentation allows each component to perform its specific function independently while working together as a unified switching system. The modular segmentation makes the complex mechanism more manageable and maintainable while achieving the desired switching flexibility.
Solution Approach 2:
The compression spring acts as an intermediary element in the rotary braking pin mechanism, providing the necessary force to maintain clamping block engagement with the grooves during rotation. This intermediary component enables smooth transitions between 3h and 6h positions while maintaining reliable electrical contact, resolving the complexity issue by introducing a simple mechanical element that facilitates the switching action.
