Curved Housing Battery Stacking for Ergonomic Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld devices with curved ergonomic designs are hindered by battery placement, which prevents a smooth arc shape due to the battery's proximity to the housing, limiting ergonomic comfort and space utilization.
Innovation Solution
The electronic apparatus design includes a housing with an accommodating space where the battery module is stacked over the motherboard, allowing the battery to be positioned between the motherboard and display module, widening its width to maintain a smooth curved surface while increasing battery capacity, and incorporating a second circuit board with a speaker that does not obstruct the curved shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the battery is placed closer to the housing to increase battery capacity, then the battery capacity increases, but the housing surface cannot present a smooth arc shape
Solution Approach 1:
The patent changes the spatial arrangement by stacking the battery module over the first circuit board in the vertical dimension, rather than placing it laterally adjacent to the housing. This vertical stacking allows the battery to be positioned between the motherboard and display module, enabling the housing surface to maintain a smooth curved shape while still accommodating a widened battery module that increases capacity.
2Quantity of substance
If the battery module is widened to increase capacity, then the battery capacity increases, but it obstructs the curved shape of the housing
Solution Approach 1:
The battery module is positioned in the vertical stacking arrangement between the first circuit board and display module, utilizing the Z-axis dimension rather than expanding laterally in the X-Y plane. This dimensional shift allows the battery to be widened in capacity without protruding laterally to obstruct the curved housing surface continuity.
3Adaptability or versatility
If additional components like speakers are added to increase functionality, then the device functionality increases, but the internal space utilization becomes more complex
Solution Approach 1:
The second circuit board with the speaker is integrated into the existing stacking arrangement beside the battery module, sharing the vertical space between the first circuit board and display module. This merging approach allows additional functionality to be added without creating separate lateral compartments, thereby managing internal space complexity while increasing device versatility.
