Stepped Battery Layout With Bent Display Substrate for Slim Endurance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing power consumption in electronic devices due to added features leads to higher battery capacity requirements, which often results in larger, thicker batteries that compromise device usability.
Innovation Solution
The electronic device incorporates a stepped battery arrangement, where the battery is partially housed in a second accommodating cavity defined by the first support plate, optimizing space utilization and enhancing battery capacity without increasing device thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery capacity is increased to meet higher power consumption requirements, then device endurance time is extended, but device thickness increases compromising usability
Solution Approach 1:
The bent part of the array substrate is nested within the first accommodating cavity formed by the support body, transition part, and step part. This allows the substrate to utilize the vertical space within the cavity, enabling increased battery capacity without increasing the overall device thickness.
Solution Approach 2:
The array substrate transitions from a flat two-dimensional structure to a three-dimensional bent structure by forming a bent part that extends into the first accommodating cavity. This dimensional change allows the substrate to occupy additional vertical space, accommodating the increased battery capacity requirement while maintaining the device's thin profile.
2Quantity of substance
If battery size is increased to provide higher capacity, then power consumption requirements are met, but device volume increases negatively impacting usability
Solution Approach 1:
The support plate is segmented into multiple functional parts: a support body, a transition part, and a step part. These segments create distinct accommodating cavities that efficiently organize and maximize the battery's placement, allowing increased battery capacity within the same device volume.
Solution Approach 2:
The battery is arranged in a stepped configuration that utilizes the vertical dimension created by the first and second accommodating cavities. This three-dimensional arrangement allows the battery to achieve higher capacity without proportionally increasing the device's overall volume.
