Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional waterproof audio connector uses multiple components (isolation main body, side cover, terminal slot protection walls) to seal gaps, then waterproofing is improved, but device complexity increases and assembly becomes difficult
Solution Approach 1:
The patent combines multiple waterproofing components (isolation main body, side cover, terminal slot protection walls) into a single integrated isolation base structure. The isolation base includes pre-formed assembly slots with built-in waterproof features, eliminating the need for separate side covers and protection walls, thus simplifying the structure while maintaining waterproofing effectiveness.
Solution Approach 2:
The isolation base is segmented into functional regions including assembly slots with integrated waterproof sealing structures. Each signal terminal has a dedicated assembly slot with waterproof features, allowing modular assembly while maintaining overall waterproof integrity without requiring complex external sealing components.
2Manufacturing precision
If signal terminals are positioned and structured differently to correctly connect audio signals, then signal transmission accuracy is improved, but assembly difficulty increases
Solution Approach 1:
The isolation base is pre-formed with assembly slots that have specific geometries matching the signal terminal structures. The slots include positioning features and waterproof sealing structures that automatically align and seal when terminals are inserted, eliminating the need for complex post-assembly adjustments or sealing operations.
Solution Approach 2:
Different regions of the assembly slots have different structural characteristics tailored to specific signal terminal requirements. Each slot can have customized geometry, positioning features, and waterproof sealing structures appropriate for its designated terminal, allowing precise signal terminal positioning while simplifying assembly through form-fit insertion.
3Manufacturing precision
If signal terminals are extended and crisscrossed to enable precise soldering, then connection precision is improved, but manufacturing cost and yield rate deteriorate
Solution Approach 1:
Instead of extending signal terminals in three-dimensional crisscross patterns, the patent uses the vertical dimension of the assembly slots to achieve precise positioning. Terminals are inserted vertically into slots that provide positioning constraints in horizontal dimensions, achieving precise soldering alignment through vertical insertion rather than complex spatial arrangement.

AI summary
The present invention is to provide a waterproof audio connector which includes an isolation base mounted in the electronic device, having an inserting port and an assembly port respectively at a front end and a rear end thereof, having a plurality of first assembly slots longitudinally and concavely disposed at an inner surface thereof between the two ports; a plurality of signal terminals each having a contacting portion at the end thereof and fastened with the first assembly slot corresponding thereto; an isolation plate having a side surface abutted against outer edges of the first assembly slots and forming a filler space between another side surface thereof and an edge of the assembly port; and a waterproof sealant formed by waterproof glue which is filled into the filler space and solidified later, so as to watertightly seal all gaps among the signal terminals, the isolation plate and the assembly port.
