Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the plug and socket are encapsulated to achieve waterproof connection, then waterproof performance is improved, but the connector cannot be directly used in water or other conducting media
Solution Approach 1:
The connector is divided into separate functional zones: the isolating cavity that provides waterproof enclosure, the gating isolate component with dielectric elastomer that enables selective isolation, and the contact elements. This segmentation allows different parts to perform specialized functions - the cavity provides baseline waterproofing while the gating component adds the capability for controlled isolation when in water.
Solution Approach 2:
The dielectric elastomer acts as an intermediary element between the conductor and the external environment. It provides electrical isolation while allowing mechanical deformation, enabling the connector to adapt to water immersion while maintaining safe electrical isolation. The elastomer mediates between the need for electrical conduction and the need for waterproof isolation.
2Reliability
If the plug and socket are connected to enable electrical conduction, then electrical connectivity is improved, but water or other media can cause damage or electric shocks
Solution Approach 1:
The harmful factor (water/media) is extracted from the electrical conduction path by introducing the isolating cavity and gating isolate component. These elements physically separate the conductor from direct contact with water while maintaining electrical functionality through the dielectric elastomer mechanism.
Solution Approach 2:
The gating isolate component is designed to preemptively prevent water ingress and electrical short circuits before they can occur. The dielectric elastomer provides preliminary isolation protection, and the structure is configured to maintain safe isolation states before any harmful contact can happen.
3Ease of manufacture
If the connector structure is simplified for ease of manufacture, then manufacturing cost is reduced, but waterproof and insulation performance cannot be completely realized
Solution Approach 1:
The dielectric elastomer is implemented as a thin flexible film that provides both structural integrity and electrical isolation functionality. This thin-film approach achieves comprehensive waterproof and insulation protection without requiring bulky or complex structures, maintaining manufacturing feasibility while ensuring complete isolation performance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables electrical devices to function safely and maintain waterproof insulation in water or other media, preventing damage and electric shocks by isolating the contact points and ensuring continuous conduction through the conductors.
Implementation Method 1
the component may be subject to elastic deformation to move the moving conductor within the elastic deformation range of the dielectric elastomer
Implementation Method 2
a gating isolate component made of conductor and dielectric elastomer... The gating isolate component isolates passing of water and other media and solely allows conduction of electricity
Implementation Method 3
the isolating cavity, consisting of a shell and a hollow waterproof ring, is deformed as the hollow water rings undergoes elastic deformation when connected

AI summary
A water-proof insulation connector includes a gating isolation assembly. A contactor (13) and an isolation cavity are isolated by the gating isolation assembly. The contactor is connected with a device connected by an interface. The gating isolation assembly includes a movable conductor (14) and an elastic insulator (15), and is used to isolate water or other mediums. The elastic insulator can have elastic deformation so as to make the movable conductor move in the range of its elastic deformation to achieve disconnection or connection of the movable conductor and the contactor.
