Electrical Socket Plastic Peg Elastic Buckle Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical sockets with metal electrodes and pins experience poor locking due to low friction coefficient and electrode wear over time, leading to instability and easy detachment of plugs.
Innovation Solution
An electrical socket design featuring a housing with elastic buckles, a slider, and a first peg made of plastic, which inserts through holes to securely lock the plug by increasing the distance between elastic pieces and engaging with locking holes, providing a stable locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal electrodes press upon metal pins to hold them, then the electrical socket has a locking function, but the friction coefficient is small and the locking effect is reduced over time
Solution Approach 1:
The patent changes the material parameter of the locking component from metal to plastic, which has a higher friction coefficient. This parameter change increases the friction between the locking component and the pin, thereby improving the locking effect and its duration without requiring continuous electrode pressure.
Solution Approach 2:
The patent introduces a plastic locking component as an intermediary between the electrode and the pin. This locking component mediates the holding function by providing increased friction and a mechanical interlocking mechanism through the through-hole structure, replacing the direct metal-to-metal contact that provided insufficient friction.
2Reliability
If metal electrodes are used for connection, then electrical conductivity is achieved, but the electrodes are prone to wear out reducing locking effect
Solution Approach 1:
The patent segments the locking function from the electrical connection function. The electrode remains solely for electrical connection, while a separate plastic locking component handles the mechanical holding function. This segmentation prevents wear on the electrode from affecting the locking effect, as the locking component is designed to accommodate normal connection/disconnection cycles.
Solution Approach 2:
The patent uses composite material strategy by combining metal electrodes for electrical conductivity with a plastic locking component for mechanical strength and friction. The plastic material provides wear resistance and high friction coefficient, while the metal electrode maintains electrical connection, creating a system where each material performs its optimal function.
3Reliability
If a locking mechanism is added to prevent detachment, then security is improved, but the device complexity increases
Solution Approach 1:
The patent merges the locking component with the existing electrode structure by positioning the locking component on the electrode and using the electrode's through-hole as the locking mechanism's through-hole. This merging allows the locking function to be achieved without adding completely separate structural elements, thereby limiting the increase in device complexity.
