Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic packages with molded battery holders face issues such as high temperatures affecting battery performance, battery expansion/contraction causing damage, increased size and cost due to battery placement next to components, and limitations in component packaging density.
Innovation Solution
An electronic package design using a domed lid to enclose a battery and die, eliminating molded holders, with electrical connections through the lid and substrate, allowing for compact size and efficient component integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If molded battery holders are used to secure batteries, then battery positioning is improved, but package size increases and manufacturing complexity increases
Solution Approach 1:
The patent merges the battery holder function with the domed lid structure. The domed lid itself serves as both the protective enclosure and the battery mounting surface, eliminating the need for separate molded battery holders. The battery is directly attached to the inner surface of the domed lid, integrating multiple functions into a single component.
Solution Approach 2:
The domed lid performs multiple functions: it provides mechanical protection for the battery, serves as the mounting structure for battery attachment, and acts as part of the electrical connection path. This multi-functional design eliminates the need for dedicated battery holders while maintaining secure battery positioning.
2Reliability
If molded battery holders are used to secure batteries, then battery positioning is improved, but device complexity increases
Solution Approach 1:
The patent combines the battery holder function with the domed lid structure. The domed lid itself serves as both the protective enclosure and the battery mounting surface, eliminating the need for separate molded battery holders. The battery is directly attached to the inner surface of the domed lid, integrating multiple functions into a single component.
Solution Approach 2:
The patent extracts and eliminates the separate molded battery holder component from the packaging structure. By removing this unnecessary intermediate component and directly attaching the battery to the domed lid, the overall device complexity is reduced while maintaining functional integrity.
3Device complexity
If battery is placed next to electronic components, then electrical connection is simplified, but package size increases
Solution Approach 1:
The patent changes the spatial arrangement from a lateral placement (battery next to components on the same plane) to a vertical integration (battery enclosed within the domed lid structure). The battery is positioned in the vertical space above the substrate, connected through the domed lid, which reduces the horizontal footprint while maintaining electrical connectivity.
Solution Approach 2:
The patent nests the battery within the domed lid enclosure, which itself is mounted on the substrate containing electronic components. This nested arrangement allows the battery and electronic components to occupy different spatial zones within the same package volume, reducing overall package size while maintaining functional separation and connection.
4Ease of manufacture
If conventional packaging is used, then manufacturing process is simple, but component density is limited
Solution Approach 1:
The patent transitions from two-dimensional planar packaging to three-dimensional vertical integration. The domed lid structure creates a vertical enclosure that accommodates the battery above the substrate level, utilizing the third dimension (height) to increase component density without complicating the manufacturing process.
Solution Approach 2:
The patent implements a nested packaging structure where the battery is enclosed within the domed lid, which is mounted on the substrate. This nested arrangement maximizes the use of available package volume by stacking components vertically, thereby increasing component density while maintaining manufacturing simplicity.
