Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adapter plug projects outward relative to the surface of the adapter body, then the electrical connection is achieved, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The adapter plug is nested within the adapter body through a recess structure. The plug housing is received within a recess of the adapter body, allowing the plug to be integrated into the body rather than projecting outward. This nesting approach simplifies the overall structure and makes the plastic molding process easier and more cost-effective while maintaining electrical connection functionality.
Solution Approach 2:
Instead of having the plug project outward from the body surface, the design inverts the arrangement by creating a recess in the body that receives the plug. This inversion of the traditional projection approach resolves the manufacturing complexity issue while achieving the same electrical connection function.
2Reliability
If the adapter plug projects outward, then the contact pins can be connected with the plug, but the structural complexity increases making it difficult to fabricate
Solution Approach 1:
The plug housing is nested within the recess of the adapter body, creating a compact integrated structure. The contact pins are positioned within the plug housing, and the electrode structures are received within half-pipe portions of the electrode structures on the circuit board. This nested arrangement reduces structural complexity compared to a projecting plug design.
Solution Approach 2:
The recess structure of the adapter body and the plug housing are designed to combine into a unified assembly. The engagement between the recess and plug housing merges the body and plug into a single functional unit, reducing the number of separate components and simplifying the overall structure while maintaining electrical connection capabilities.

AI summary
The invention provides a power adapter combination including an adapter body and an adapter plug. The adapter body comprises a first casing having an inner space and a receiving recess structure with one side opened through the inner space, a circuit board disposed in the inner space, and a pair of connection terminals electrically connected with the circuit board and partially extending into the receiving recess structure. The adapter plug is detachably engaged into the receiving recess structure and comprises a second casing having a pair of slots thereon and a rear wall having a pair of holes, a bottom plate adapted to be assembled with the second casing, a pair of contact pins of which each has one pivoted end, is placed in one of the slots and is enabled to extend out of said one slot by rotation, and a pair of electrode structures mounted on the bottom plate and electrically connected with the contact pins, respectively. Each electrode structure has a half-pipe portion, wherein the pair of connection terminals are allowed to pass through the pair of holes of the rear wall of the second casing to electrically plug into the pair of half-pipe portions, respectively.
