Multi-PCB Battery Layout With Overlapping Connection Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with limited internal space, the increasing number of electronic components and larger connectors on printed circuit boards (PCBs) lead to reduced design efficiency and increased manufacturing costs, while integrating PCBs and connection members can complicate repairs.
Innovation Solution
The electronic device configures multiple PCBs with a battery positioned between them, using separate connection members that overlap or pass by the battery to electrically connect the PCBs, allowing for efficient component arrangement and reducing costs by avoiding integral configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more electronic components are included to increase device functionality, then the device can perform more functions, but the area available for printed circuit board installation decreases due to limited internal space
Solution Approach 1:
The printed circuit board system is divided into multiple separate PCBs (first PCB, second PCB, third PCB) instead of using a single large PCB. This segmentation allows the components to be distributed across multiple smaller boards that can be arranged to fit within the limited internal space while maintaining all required functionalities.
Solution Approach 2:
The patent transitions from a two-dimensional layout on a single PCB to a three-dimensional arrangement of multiple PCBs stacked or positioned at different levels within the device housing. This dimensional change enables better space utilization by arranging PCBs around the battery and other components in the vertical and lateral dimensions.
2Adaptability or versatility
If the number of connection terminals is increased to support more components, then more components can be connected, but the connector size increases which reduces PCB design efficiency
Solution Approach 1:
The connection system is segmented into multiple connection members (first connection member, second connection member, third connection member) distributed across different PCBs. Each connection member handles a subset of the total connections, avoiding the need for a single large connector with many terminals. This distributes the connection load and maintains manageable connector sizes.
Solution Approach 2:
The patent introduces connection members that act as intermediaries between different PCBs, allowing electrical connections to be established through multiple smaller interface points rather than requiring direct large-scale connectivity. The connection members serve as intermediate connection points that simplify the overall connection architecture.
3Device complexity
If connectors are removed and PCBs are integrally configured with connection members, then connector size issues are eliminated, but manufacturing cost increases and ease of repair deteriorates
Solution Approach 1:
The system maintains segmentation between PCBs and connection members as separate, removable components rather than integrating them into a single inseparable unit. This allows individual PCBs and connection members to be independently replaced or repaired, improving maintainability while avoiding the need for complex integral configurations.
