Engineering Contradiction Analysis
1Power
If two DC-in jacks are used to achieve high power, then power output increases to 500 watts or more, but device complexity increases and manufacturing costs rise
Solution Approach 1:
The patent combines multiple power input functions into a single DC-in jack. The system connector integrates multiple terminals (system input terminal, system positive terminal, system negative terminal) that can accept different power supply configurations, eliminating the need for separate DC-in jacks while maintaining the capability to deliver 500 watts or more power output.
2Power
If two DC-in jacks are used to achieve high power, then power output increases to 500 watts or more, but manufacturing costs increase due to complex structure and mold making
Solution Approach 1:
The patent consolidates what would require two separate DC-in jacks into a single integrated system connector. This reduces the number of components, simplifies mold making, and decreases assembly complexity, thereby lowering manufacturing costs while maintaining the high power output capability of 500 watts or more.

If system positive lines and system negative lines are disposed on the circuit board with overlapping projections, then space is saved, but short circuit risk increases and heat dissipation deteriorates
Solution Approach 1:
The patent transitions from a two-dimensional overlapping layout to a three-dimensional spatial separation. The system positive terminal and system negative terminal are positioned at different locations on the circuit board such that their orthographic projections do not overlap. This spatial separation prevents short circuits while maintaining efficient space utilization through optimized routing of the system positive lines and system negative lines.
Solution Approach 2:
The patent segments the power transmission paths by separating the system positive lines and system negative lines into distinct routing paths on the circuit board. This segmentation ensures that the orthographic projections of the terminals do not overlap, eliminating short circuit risks while allowing independent optimization of each line's heat dissipation characteristics.
4Area of stationary object
If system positive lines and system negative lines are disposed on the circuit board with overlapping projections, then space is saved, but heat dissipation deteriorates
Solution Approach 1:
The patent uses spatial separation in the planar dimension to improve thermal management. By positioning the system positive terminal and system negative terminal such that their orthographic projections do not overlap, the design creates sufficient physical distance between high-current paths, reducing thermal interference and improving heat dissipation while maintaining compact overall device dimensions.
