Engineering Contradiction Analysis
1Reliability
If solid printed circuit boards are used for interconnectivity, then electrical connection is achieved, but substantial space is required in the enclosure
Solution Approach 1:
The solid printed circuit board is segmented into a lattice structure consisting of intersecting strips that form framed slots. This segmentation reduces the material usage and space occupation while maintaining the electrical connection function through the connector elements that engage within the framed slots.
Solution Approach 2:
The solid PCB is replaced with a porous lattice structure that has gaps and framed slots. This porous design allows cooling air to flow through the enclosure while maintaining structural support and electrical connectivity, thereby reducing space requirements without compromising functionality.
2Reliability
If solid printed circuit boards are used for interconnectivity, then electrical connection is achieved, but cooling air circulation is hindered
Solution Approach 1:
The lattice structure with gaps and framed slots creates a porous configuration that permits cooling air to circulate freely through the enclosure. This design maintains electrical connectivity through the connector elements while eliminating the barrier effect of solid PCBs, thereby improving thermal management.
Solution Approach 2:
By segmenting the solid board into intersecting strips with gaps, the design creates pathways for air flow. The segmented structure reduces thermal resistance and enables efficient heat dissipation while preserving the electrical connection functionality.
3Area of stationary object
If a lattice structure is used to reduce space and improve air flow, then space efficiency and cooling are enhanced, but alignment precision of connectors is required
Solution Approach 1:
The framed slots in the lattice structure serve as intermediary elements that guide and align the connector elements. The slots act as mechanical guides that ensure precise positioning and orthogonal engagement of connectors, thereby reducing the tolerance requirements and simplifying the alignment process.
Solution Approach 2:
The lattice structure with framed slots provides self-aligning features that automatically position the connectors during assembly. The geometric constraints of the slots and strips create natural alignment paths, enabling the system to self-correct minor positioning errors without requiring high-precision manufacturing.
