Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cable connectors are used, then cable connection is achieved, but the connection process is complex and requires cutting and stripping of cables
Solution Approach 1:
The connector is divided into a housing base and a cover element that can be displaced between open and closed positions. This segmentation allows the cable connection process to be simplified: the cover element opens to receive the cable and closes to secure it, eliminating the need for complex cutting and stripping operations.
Solution Approach 2:
The housing base and cover element are pre-configured with receiving spaces and fixing elements positioned to automatically engage with the cable. When the cover element is closed, the fixing elements are already in the correct positions to secure the cable, eliminating the need for on-site cutting and stripping preparations.
2Reliability
If conventional cable connectors are used, then cable connection is achieved, but mechanical loads and vibrations are not adequately withstood
Solution Approach 1:
The connector combines features of both cable connectors and PCB connectors into a single integrated device. The housing base can be mounted on a PCB while the cover element provides cable securing capabilities, allowing the same component to handle both PCB integration and cable mechanical loading reliably.
Solution Approach 2:
The fixing elements are designed with curved surfaces that conform to the cable geometry. This curved design allows the fixing elements to evenly distribute mechanical loads and vibrations across the cable surface, enhancing mechanical stability while maintaining ease of cable insertion.
3Productivity
If cable connection requires cutting and stripping, then electrical contact can be made, but time is lost in preparation
Solution Approach 1:
The fixing elements are designed to automatically engage with the cable when the cover element is closed. The cable simply needs to be inserted into the receiving space, and the fixing elements self-adjust to secure it, eliminating the need for manual cutting and stripping operations and significantly reducing connection time.
Solution Approach 2:
The receiving spaces and fixing elements are pre-configured in the housing base before the cable is connected. This preliminary arrangement of components allows the cable to be directly inserted and secured without any preparation steps, maximizing connection speed and minimizing time loss.
4Adaptability or versatility
If stationary electronic device connectors are used, then PCB connection is achieved, but mechanical load resistance is insufficient
Solution Approach 1:
The connector merges the PCB mounting functionality with cable securing capabilities in a single integrated design. The housing base provides PCB mounting surfaces while the cover element with fixing elements provides mechanical load resistance, making the connector adaptable to PCB connections while withstanding mechanical stresses.
Solution Approach 2:
The connector is designed as a composite structure with the housing base and cover element working together as integrated components. This composite design allows the PCB mounting features to provide electrical connection adaptability while the cover element and fixing elements provide enhanced mechanical strength and vibration resistance.
