Integrated Laptop Power Pack Merging Adapter and Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laptop computers face a trade-off between long battery life and convenience, as conventional designs require a separate AC/DC adapter 'brick' that adds bulk and weight, necessitating a compromise on battery life for portability.
Innovation Solution
Integration of the AC/DC adapter with the battery pack within a single detachable housing, allowing for a power pack that includes both the battery and adapter, with a control circuit to manage power from either internal or external sources, ensuring 100% battery life when AC power is available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a separate AC/DC adapter brick is used to extend power capability, then power availability is improved, but device weight and bulk increase
Solution Approach 1:
The patent combines the AC/DC adapter and battery pack into a single integrated power pack unit. The adapter housing contains both the battery pack and AC/DC adapter components, eliminating the need for a separate brick and reducing overall weight and bulk while maintaining power availability.
2Use of energy by moving object
If a separate AC/DC adapter brick is used to extend power capability, then power availability is improved, but device complexity increases
Solution Approach 1:
The patent merges the AC/DC adapter and battery pack into a single integrated unit, reducing the number of separate components and connections required. This integration simplifies the overall system architecture and reduces device complexity while maintaining power availability.
Solution Approach 2:
The integrated power pack serves multiple functions: it acts as both a battery pack and an AC/DC adapter. The universal design allows the single unit to provide power in multiple modes (battery power and AC power) without requiring separate dedicated devices.
3Duration of action of moving object
If battery capacity is increased to extend battery life, then duration of action is improved, but weight and volume increase
Solution Approach 1:
The patent combines the AC/DC adapter and battery pack into a single integrated power pack unit. The adapter housing contains both the battery pack and AC/DC adapter components, eliminating the need for a separate brick and reducing overall weight and bulk while maintaining power availability.
