Socket Protection Cover with Torsion Spring Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket protection cover devices often suffer from poor reliability, leading to accidental insertions and getting stuck, which compromises electrical safety and normal usage.
Innovation Solution
A protection cover device for sockets featuring a housing with a torsion spring, a protection cover, and specific guiding slopes and holes, where the torsion spring is lap-jointed with the protection cover and bottom plate, ensuring the protection cover can only be opened when both plug probes exert balanced downward pressure, preventing accidental insertion and ensuring reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protection cover device is added to the socket, then electrical safety is improved, but device complexity increases
Solution Approach 1:
The protection cover device is nested within the socket structure. The housing integrates with the socket body, the protection cover fits within the housing, and the torsion spring is concealed within the housing structure. This nesting approach adds safety functionality while minimizing external complexity and maintaining a compact overall form factor.
Solution Approach 2:
Multiple functional components are merged into a unified structure. The housing combines support, protection, and spring mounting functions. The protection cover integrates the driving slopes and probe hole into a single piece. The torsion spring combines both the spring body and swinging arms into one integrated component, reducing the number of separate parts while maintaining safety functionality.
2Reliability
If a torsion spring mechanism is used to reset the protection cover, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The torsion spring mechanism provides automatic reset functionality. When the protection cover is pushed down by a plugged-in appliance, the spring is compressed and stores energy. Upon release, the spring automatically propels the protection cover back to its original position, eliminating the need for manual intervention. This self-service mechanism ensures reliable resetting while maintaining operational simplicity.
Solution Approach 2:
The protection cover transitions between static (protected) and dynamic (open) states through a simple pushing motion. The driving slopes convert the vertical pushing force into the necessary movement along the distribution direction, allowing users to easily open the cover by applying force in any direction while the spring handles the return motion dynamically.
3Manufacturing precision
If driving slopes are added to guide the protection cover, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The driving slopes utilize inclined planar surfaces that guide the protection cover smoothly during movement. These sloped surfaces convert vertical pressing forces into controlled translational motion along the distribution direction of the insertion holes. The curved or inclined geometry of the slopes provides precise positioning guidance while maintaining simple geometric forms that are easy to manufacture using standard machining or molding processes.

Function Achieved in This Case
The solution effectively prevents accidental insertion and ensures reliable performance without affecting normal use by requiring balanced pressure from both plug probes to open the protection cover, thus enhancing electrical safety and usability.
Implementation Method 1
a torsion spring, which is configured to reset the protection cover. The torsion spring may include a spring body, a first swinging arm fixedly connected to the spring body and a second swinging arm fixedly connected to the spring body
Implementation Method 2
