Problem
Miniaturized automobile chargers, known as 'bullet chargers,' are difficult to track and store within a vehicle's shifting environment, leading to potential loss, and existing solutions do not effectively provide a unified charging solution between automobile DC sources and home AC outlets.
Innovation Solution
A compact home wall charger with pivotal AC prongs and a cylindrical compartment for storing a bullet charger, equipped with an AC to DC power converter, allowing the bullet charger to be used with both automobile DC sources and home AC outlets, and featuring a movable cover for easy access and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If bullet chargers are miniaturized for portability, then they become easier to carry, but they become difficult to track and store within the automobile interior
Solution Approach 1:
The patent implements a nested storage solution where the cylindrical compartment houses the bullet charger within the wall charger housing. The bullet charger is stored inside the housing structure, with the cylindrical compartment acting as a container within the larger wall charger unit. This nesting approach allows the miniaturized charger to be conveniently stored and tracked within the automobile's wall charger, preventing loss while maintaining portability.
2Ease of operation
If a wall charger with storage compartment is designed, then bullet charger storage and organization is improved, but device complexity increases
Solution Approach 1:
The wall charger is segmented into distinct functional components: the main housing structure, the cylindrical storage compartment, the movable cover mechanism, and the bullet charger. This segmentation allows each component to perform its specific function independently while contributing to the overall storage organization capability. The modular design manages complexity by dividing the system into manageable, functionally-specific segments.
Solution Approach 2:
The cylindrical compartment is nested within the wall charger housing, creating a compact integrated storage solution. This nesting approach organizes the bullet charger within the wall charger structure without requiring separate external storage devices, thereby improving storage organization while controlling overall device complexity through integrated design.
3Adaptability or versatility
If AC to DC power converter is added to enable bullet charger use with AC outlets, then charging versatility is improved, but device complexity and cost increase
Solution Approach 1:
The wall charger system achieves multi-functionality by incorporating an AC to DC power converter that enables the bullet charger to operate with both AC wall outlets and DC automobile outlets. The same bullet charger design can be used in both charging environments, providing universal charging capability. This multi-functional approach improves adaptability while managing complexity by using a single charger design for multiple power sources.
Solution Approach 2:
The AC to DC power converter acts as an intermediary component that adapts AC power from wall outlets into DC power compatible with the bullet charger. This intermediary device enables the bullet charger to function with AC outlets without modifying the charger itself, thereby improving charging versatility while isolating the power conversion complexity from the charger design.
4Ease of operation
If movable cover is added to cylindrical compartment for easy access, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The cylindrical compartment incorporates a movable cover that can be opened and closed to provide access to the stored bullet charger. This dynamic element allows easy access to the charger when needed while maintaining a compact, organized storage configuration when the cover is closed. The movable cover mechanism provides operational convenience with minimal added complexity through a simple opening/closing action.
