Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If right-angle connections and elevated configurations are used for connector systems, then reliable electrical connection between motherboard and graphics board is achieved, but the overall thickness and complexity of the information handling system increases
Solution Approach 1:
The patent transitions from traditional right-angle (90-degree) connector configurations to a planar/coplanar arrangement where the motherboard and graphics board lie in the same plane. This dimensional reconfiguration eliminates the need for vertical elevation and right-angle transitions, thereby reducing overall system thickness while maintaining electrical connection reliability through direct edge-to-edge contact between connector arrays.
Solution Approach 2:
The patent employs flexible jumper cables with thin-profile construction to bridge the electrical connection between the motherboard connector array and the graphics board connector array. These flexible cables can be routed in thin configurations without requiring bulky right-angle connectors, enabling reliable electrical connectivity while maintaining a reduced thickness profile for the overall system.
2Reliability
If traditional connector systems with right-angle connections are used, then electrical connectivity is established, but design complexity and manufacturing costs increase
Solution Approach 1:
The patent divides the connector system into separate, modular components: a motherboard-mounted connector array, a graphics board-mounted connector array, and intermediate flexible jumper cables. This segmentation allows each component to be optimized independently and simplifies the overall assembly process, reducing design and manufacturing complexity compared to integrated right-angle connector solutions.
Solution Approach 2:
The flexible jumper cable assembly serves multiple functions: it provides electrical connectivity, allows for planar board arrangement, and can accommodate various cable routing configurations. This multi-functionality reduces the need for specialized right-angle connectors and simplifies the overall connector system design, thereby reducing device complexity and manufacturing costs.
3Length of moving object
If coplanar arrangement of motherboard and graphics board is implemented, then thickness is reduced and heat pipe configuration is simplified, but precise alignment of connector arrays is required
Solution Approach 1:
The patent introduces flexible jumper cables as intermediary elements between the motherboard connector array and the graphics board connector array. These cables provide alignment tolerance and can accommodate minor positional variations, reducing the stringency of alignment precision requirements while maintaining the benefits of coplanar arrangement and reduced thickness.
Solution Approach 2:
The patent utilizes the flexibility and adjustability of the jumper cable parameters (length, routing angle, tension) to compensate for variations in connector array positioning. By allowing parameter changes in the cable configuration rather than requiring fixed precision alignment, the system achieves coplanar arrangement with reduced manufacturing precision requirements.
