Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fixing method is used for leads to connectors, then the connection is stable, but the assembly and disassembly process becomes complicated and time-consuming
Solution Approach 1:
The connector is divided into an upper cover and a base that can be separated, with the lead passing through both parts. The fastener is a separate component that can be independently inserted and operated. This segmentation allows the lead to be fixed securely when assembled but easily released when disassembled, resolving the contradiction between stable connection and easy assembly/disassembly.
Solution Approach 2:
The fixing mechanism transitions from a static conventional method to a dynamic system where the fastener can be inserted to secure the lead or removed to release it. The upper cover and base can be separated, allowing the lead to be quickly released without complex tools. This dynamic design enables both stable fixation during use and convenient assembly/disassembly.
2Reliability
If the lead is firmly fixed to ensure electrical connection, then the connection reliability improves, but the time required for assembly and disassembly increases
Solution Approach 1:
The fastener is pre-positioned in the upper cover, and the lead is pre-routed through both the upper cover and base. When assembling, the fastener is simply inserted to immediately secure the lead, and when disassembling, the fastener is removed to instantly release the lead. This preliminary arrangement of components eliminates time-consuming adjustment steps while ensuring reliable electrical connection when assembled.
Solution Approach 2:
The fastener is extracted as a separate, removable component from the connector assembly. This allows the lead to be firmly fixed when the fastener is inserted, but enables quick release by simply removing the fastener without disassembling the entire connector. This extraction principle resolves the contradiction between firm fixation and quick assembly/disassembly.
3Ease of manufacture
If a simple fastening structure is used, then the assembly process is simplified, but the electrical connection stability may be compromised
Solution Approach 1:
The connector combines multiple functions into a unified structure: the upper cover and base form a protective enclosure, the fastener provides both mechanical fixation and electrical contact, and the lead routing through both parts ensures stable positioning. This merged design achieves reliable electrical connection through the combined action of multiple simple components without requiring complex assembly procedures.

AI summary
A connector, an electrical stimulation system, and an assembly method of the electrical stimulation system are provided. The connector is adapted to fix a lead and to electrically connect the lead to an electrical stimulation device. The lead includes a filament and an insulation layer. The connector includes an upper cover, a base, an electrical pad, and a first fastener. The upper cover has a top portion. The base combined with the upper cover has a bottom portion. At least one of the upper cover and the base forms an opening. The electrical pad is disposed on the bottom portion. The first fastener is passed through the top potion and is locked toward a direction of the bottom portion. The lead is inserted into the connector from the opening. The first fastener moves along the direction toward the bottom portion to damage the insulation layer of the lead.
