Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial industrial sockets for electric vehicles lack effective dustproof and contact terminal protection designs, leading to potential charging performance issues and safety risks due to dust accumulation, which can cause unexpected temperature increases and even spontaneous combustion.
Innovation Solution
An industrial socket design featuring an insulation body with actuating units and elastic elements, where slant surface portions and cover portions shield electrical ends when not in use, but retract to allow plug insertion and connection, providing fool-proof, dustproof, and contact protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective cover is added to shield the receiving opening, then dustproof performance is improved, but device complexity increases
Solution Approach 1:
The patent combines the protective cover function with the actuating unit mechanism into a single integrated assembly. The cover portion and actuating unit form one component that performs both protection and controlled opening functions, eliminating the need for separate protective cover and actuating mechanisms.
Solution Approach 2:
The actuating unit serves multiple functions: it acts as both the protective cover shield and the mechanism for opening/closing the receiving opening. This multi-functional design reduces the number of separate components needed in the system.
2Reliability
If multiple elements are added for contact protection, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the contact protection function into the actuating unit mechanism. The cover portion naturally shields the electrical connectors when closed, and the same mechanism that opens the receiving opening also exposes the contacts for connection, eliminating the need for separate contact protection components.
3Reliability
If a complex locking mechanism is added, then fool-proof performance is improved, but ease of operation deteriorates
Solution Approach 1:
The actuating unit is designed as a dynamic component that automatically transitions between closed and open states based on plug insertion. The elastic element provides automatic resetting action, creating a dynamic system that adapts to the presence or absence of a plug without requiring manual intervention.
Solution Approach 2:
The elastic element automatically returns the actuating unit to its initial closed state after plug removal, providing self-service functionality. The system automatically resets itself without requiring user action, maintaining the protective state ready for the next connection.

AI summary
Disclosures of the present invention describe an industrial socket, comprising: an insulation body, a plurality of electrical connectors, a plurality of actuating units, and a plurality of elastic elements, wherein each of the actuating units comprises a slant surface portion and a cover portion. It is worth explaining that, when an electrical plug is inserted into a receiving opening of the insulation body, the slant surface portion enters a notch by a pushing force applied by the electrical plug, such that the cover portion correspondingly moves with the motion of the slant surface portion, so as to stop the shielding to an electrical end of the electrical connector. Therefore, this novel industrial socket has many outstanding functions of fool-proof, dustproof and contact protection.
