Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing information handling systems face challenges with non-standardized battery connections, leading to increased inventory, manufacturing complexity, and potential system damage during battery removal or assembly, especially in portable configurations.
Innovation Solution
A battery connector system with a switch that enables and disables power transfer, allowing for standardized connections across multiple platforms, and includes a detection circuit for initiating a hard reset during battery connection/disconnection, supporting both horizontal sliding and vertical insertion methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-standardized battery connections are used to accommodate different internal space configurations, then the battery can fit within the portable housing, but inventory and manufacturing complexity increase
Solution Approach 1:
The battery connector is designed with a universal structure that can accommodate different internal space configurations through standardized connection interfaces. The connector includes a housing with positioning features and electrical contacts that work across multiple battery types and configurations, eliminating the need for multiple specialized connectors while maintaining adaptability to different housing layouts
2Duration of action of stationary object
If the system remains powered on during battery removal or assembly, then system operation is maintained, but system damage can occur from inadvertent discharge
Solution Approach 1:
The connector incorporates a switch mechanism that automatically disables power transfer before the battery is fully removed or during the connection process. This preliminary action of cutting power prevents inadvertent discharge and system damage while allowing the system to remain powered on through alternative power sources or graceful shutdown procedures
Solution Approach 2:
A switch component acts as an intermediary between the battery connector and the system motherboard, controlling the flow of electrical power. This intermediary mechanism ensures that power transfer is selectively enabled or disabled based on the connection state, preventing harmful discharge while maintaining system operation continuity
3Adaptability or versatility
If multiple battery connector types are maintained for different configurations, then specific connection requirements are met, but inventory expense increases
Solution Approach 1:
A single standardized battery connector design is developed that can serve multiple connection configurations through its universal interface. The connector incorporates positioning features, electrical contacts, and mechanical engagement elements that work across different battery types and housing layouts, eliminating the need to maintain multiple specialized connector inventories while preserving compatibility with various system configurations

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. A switch included in the connector cuts of power communication from the battery by disconnecting an SMBus data interface when the switch moves to an off position.
