Solution Overview
Problem
The battery duration and charging capacity of mobile devices, particularly those with multiple display units, have not kept pace with advancements in cellular phone technology, leading to short usage times before needing recharging, especially due to high energy consumption from display screens and everyday activities.
Innovation Solution
A rechargeable battery case system designed as a carrying case that provides a non-removable power source, capable of being charged via external sources, and equipped with a modular battery that can power mobile devices continuously for extended periods, up to seven days, through various charging mechanisms including USB, wireless, and solar power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a larger battery is installed in the mobile device, then battery duration is improved, but device size and weight increase
Solution Approach 1:
The battery system is divided into two separate components: a small battery integrated into the mobile device for immediate use, and a larger external battery pack that can be carried separately and connected when needed. This segmentation allows the device to maintain its original lightweight design while providing access to extended battery capacity through the external pack.
Solution Approach 2:
The invention employs a nested structure where the mobile device can be placed inside or connected to the external battery pack, which contains its own power source. The device essentially nests within or connects to the larger battery system, allowing the smaller device battery to operate independently while the external pack provides supplemental power when connected.
2Duration of action of moving object
If a larger battery is installed in the mobile device, then battery duration is improved, but device volume increases
Solution Approach 1:
The battery capacity is segmented between the mobile device and an external battery pack. The device maintains its original compact volume with its native battery, while the external pack provides additional capacity that can be attached or detached as needed, eliminating the need to increase device volume.
Solution Approach 2:
Instead of increasing battery capacity within the same dimensional space (which would increase device volume), the invention extends the power system into an external dimension. The additional battery capacity resides in a separate external unit that connects to the device, effectively adding power capacity without adding internal volume.
3Adaptability or versatility
If multiple display screens are added to the device, then functionality and user interface are improved, but energy consumption increases
Solution Approach 1:
The external battery pack performs preliminary action by storing additional energy in advance. When the device with multiple power-hungry displays is connected to the external pack, the additional capacity is already available to support the high energy demands of multiple screens, preventing battery depletion during extended usage.
Solution Approach 2:
The invention changes the power availability parameter by introducing an external energy source with higher total capacity. This parameter change allows the device to sustain multiple display screens for longer periods, effectively supporting the increased functionality without being constrained by the original battery's energy limits.
4Duration of action of moving object
If a portable power bank is carried, then battery duration is improved, but convenience and portability are reduced
Solution Approach 1:
The invention merges the protective case function with the external battery pack into a single integrated unit. The case not only protects the mobile device but also houses the additional battery capacity and provides charging functionality. This merging eliminates the need to carry separate power bank and case, improving convenience by combining multiple functions into one accessory.
Solution Approach 2:
The external battery pack is designed with multi-functionality, serving as both a protective case for the device and a portable power source. This universal design allows the single accessory to fulfill multiple roles: protection, extended power supply, and potential charging protection, thereby improving ease of operation by reducing the number of separate items needed.
