Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter circuit is added on the PCB or filtering wire is used to remove noises and interference, then voltage stabilization is achieved, but production cost increases
Solution Approach 1:
The patent combines the filter circuit with the DC connector by integrating the first and second connecting parts directly into the connector structure. This merging eliminates the need for separate filtering components on the PCB, achieving voltage stabilization while reducing overall production cost through component consolidation.
Solution Approach 2:
The DC connector acts as an intermediary component that incorporates filtering functionality. By placing the filter circuit within the connector itself, it mediates between the power source and the electronic device, providing noise filtering and voltage stabilization at the point of connection rather than requiring additional components elsewhere in the system.
2Object-affected harmful factors
If filtering components are added to stabilize voltage, then signal interference is reduced, but device complexity increases
Solution Approach 1:
The filter circuit is merged with the DC connector structure, combining multiple functions (connection and filtering) into a single component. This reduces device complexity by eliminating separate filtering stages while still effectively reducing signal interference through the integrated filtering capability.

AI summary
A DC connector with a voltage-stabilizing function has a tube and a wire connected with a noise-resistant filter between the tube and the wire. The tube has an upper cap and a lower opening. The lower opening has an internal terminal for electrical connection when the tube is inserted into a corresponding socket. The upper cap of the tube has a first connecting part. An outer wall of the tube near the upper ring has a second connecting part. The filter has two electrode terminals electrically connecting to the first and second connecting parts, respectively. The first and second connecting parts also electrically connect to the anode and cathode of the wires. Therefore, when an electrical signal is sent from the wire to the first connecting part, the filter provides the functions of filtering noises for stabilizing voltage.
