Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional method of peeling sheaths and wrapping with insulating tape is used, then electrical connection can be achieved, but the operation becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple functions into a single connector device: the connector housing integrates sheath peeling (via cutting blades), core connection (via conductive members), and insulation (via the housing itself replacing separate insulating tape). This merging eliminates the need for separate tools and materials, reducing operational complexity while maintaining reliable electrical connection.
Solution Approach 2:
The connector serves multiple functions simultaneously: it acts as a sheath cutter, a connection terminal, and an insulating cover. The single device performs what previously required separate operations (peeling, connecting, and insulating), making the connection process simpler and more efficient.
2Reliability
If the conventional method using insulating tape is used, then wire connection can be achieved, but special tools are required and the process becomes troublesome
Solution Approach 1:
The connector integrates the cutting blades and conductive members within a single housing that users can manipulate with one hand. The sheath peeling and wire connection functions are combined in one device that requires no separate tools, making the operation easier and more convenient.
Solution Approach 2:
The connector is designed to be self-contained with all necessary components (cutting blades, conductive members, insulating housing) integrated into a single unit that users can operate independently without requiring additional tools or materials like insulating tape.
3Ease of operation
If the conventional method is used, then wire connection can be achieved, but safety against electric shock is not guaranteed
Solution Approach 1:
The connector uses an insulating housing (shell) that completely encloses the conductive members and cutting blades after operation. This insulating shell prevents exposed conductive parts from contacting users or other conductors, eliminating electric shock risks while maintaining simple operation.
Solution Approach 2:
The insulating housing is designed to cover and protect the conductive members before any electrical connection is made or during use. This beforehand protection ensures that users are never exposed to live conductors, preventing electric shock hazards from the outset.
4Productivity
If rapid connection without tools is desired, then operation speed improves, but secure electrical connection and safety may be compromised
Solution Approach 1:
The connector combines the cutting blades and conductive members in a single integrated device, allowing sheath removal and electrical connection to occur in one continuous motion without tool changes or additional steps. This merging enables rapid connection while ensuring secure electrical contact through the integrated conductive members.
Solution Approach 2:
The self-contained design with integrated cutting blades and conductive members allows the connector to perform all necessary functions (peeling and connecting) in one operation without requiring separate tools or materials, achieving both speed and reliability.
