Solution Overview

Problem

Conventional sockets have poor assembly due to inconvenient solder bonding methods and low conductivity caused by brass conductive terminals, leading to inefficient and less reliable connections.

Innovation Solution

The socket employs a mechanical securing method using screws to secure conductive terminals within a housing, replacing chemical bonding, and utilizes a pure copper connecting part with a stainless steel securing part for enhanced conductivity and stability.

1Stability of the object's composition

If solder bonding method is used to secure conductive terminals, then the terminals are fixed in the housing, but the assembly process becomes inconvenient and complex

Engineering Contradiction:

Improveterminal fixationVSAvoidassembly convenience

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent replaces the chemical solder bonding method with a mechanical pressing method. The pressing device applies mechanical force through a pressing element that contacts the conductive terminal, securing it to the housing without requiring soldering operations. This substitution eliminates the need for soldering equipment and procedures, making the assembly process more convenient and accessible.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the bonding mechanism from chemical (solder) to mechanical (pressing force). By adjusting the pressing force parameter and the contact area between the pressing element and the terminal, the system achieves reliable fixation without the complexity of solder bonding. The pressing force can be controlled and adjusted to ensure proper securing of terminals.

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent employs a composite material structure where the conductive terminal is made of pure copper material to ensure high conductivity, while the housing or securing components may use other materials optimized for mechanical properties. This composite approach allows each component to be made from materials best suited for its specific function - copper for electrical conduction and other materials for structural support and securing.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent applies different material qualities to different parts of the terminal assembly. The conductive portion is made of pure copper with high electrical conductivity, while other portions may use materials with different properties optimized for their specific functions. This local differentiation of material quality ensures optimal performance in both conductivity and mechanical aspects.
