Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for interfacing batteries with information handling systems face challenges due to varying battery sizes, shapes, and locations, leading to increased inventory, manufacturing complexity, and potential system damage during battery removal or assembly, especially when the system gets stuck in a powered-up state.
Innovation Solution
A battery connector system with a switch that enables and disables power transfer and includes a detection circuit, allowing for standardized connections across multiple platforms, with flexible placement and fitting options, and initiates a hard reset upon connection or disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple battery types with different sizes, shapes, and locations are supported, then adaptability is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The patent implements a universal battery connector design that can accommodate multiple battery types (different sizes, shapes, and locations) through a single standardized connector interface. This universal connector reduces the number of SKU codes and inventory requirements while maintaining compatibility across various battery configurations, directly resolving the contradiction between adaptability and device complexity
2Ease of operation
If the system remains powered on during battery removal or assembly, then ease of operation is improved, but reliability deteriorates due to potential discharge damage
Solution Approach 1:
The patent incorporates a detection circuit that automatically detects battery connector insertion or removal and triggers a system reset before power management logic can respond. This preliminary action ensures the system is safely powered off during battery replacement operations, preventing discharge damage while allowing users to perform battery changes without manual power-off steps, thus resolving the contradiction between ease of operation and reliability

AI summary
An information handling system battery interfaces with a motherboard through a connector and receptacle that contribute to a standardized coupling arrangement while accommodating a wide variety of footprints and component configurations. The connector terminates to pin terminals that mount to a circuit board and gap terminals that accept a wire to accommodate different coupling arrangements. The connector conductive elements slide horizontally into receptacle conductive members or alternatively press down for a vertical coupling. Insertion of the battery connector into the battery receptacle completes a circuit detected by an embedded controller that can selectively reset the system in the event of a hangup.
