Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management circuit modules with single connectors require additional volume for components on the printed circuit board, reducing battery capacity and necessitating larger cutouts for S-bend service loops, which limits packaging efficiency and flexibility in portable electronic devices.
Innovation Solution
A dual board-to-board connector battery management circuit module utilizing a switch-back service loop, allowing for increased connector length and reduced cutouts, enabling efficient packaging and improved connection flexibility by using two connectors positioned at opposite ends of the module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single connector is used to couple the battery pack to system components, then the printed circuit board must house numerous components, but this requires additional volume within the portable electronic device, reducing battery capacity
Solution Approach 1:
The single connector is segmented into two separate board-to-board connectors positioned at opposite ends of the management circuit module. This segmentation allows components to be distributed across multiple boards rather than consolidated on one board, reducing the volume requirement for any single printed circuit board and increasing space available for the battery pack.
Solution Approach 2:
The connector arrangement transitions from a single-point connection to a distributed multi-point connection across different spatial locations. By positioning connectors at opposite ends of the module and utilizing a switch-back service loop configuration, the system distributes connections across multiple dimensions, reducing concentration of components in any single area.
2Ease of operation
If an S-bend service loop is used to enable connection between battery pack and printed circuit board, then connection is enabled, but the S-bend service loop provides insufficient length to adequately manipulate the connector and requires a larger cutout in the printed circuit board
Solution Approach 1:
The service loop is segmented into multiple sections forming a switch-back configuration rather than a single S-bend. This segmentation provides intermediate connection points and increases the effective length of the service loop, allowing adequate manipulation of connectors while reducing the size of any single cutout required in the printed circuit board.
Solution Approach 2:
The service loop configuration transitions from a planar S-bend to a three-dimensional switch-back path that utilizes vertical and horizontal spaces. This dimensional change increases the effective length of the service loop without requiring proportionally larger cutouts, as the loop可以利用s space more efficiently through its folded configuration.
