Casing-Type Charging Module with Transparent Back Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile device charging solutions that integrate an auxiliary battery into a casing often completely cover the rear surface of the device, obscuring its design and providing inadequate protection against external impacts and flexural deformation, while separate charging systems are inconvenient due to the need for additional cables and separate handling of the battery and device.
Innovation Solution
A casing-type charging module that surrounds the edges and rear surface of the mobile device with a protective casing assembly, incorporating a detachable battery assembly with magnetic and positioning guides to ensure secure coupling and exposure of the device's rear surface design, while providing impact protection and power through pogo pin connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the auxiliary battery is integrated into a casing that completely covers the rear surface of the mobile device, then the device is protected from external impacts and scratches, but the rear surface design of the mobile device is obscured and cannot be viewed
Solution Approach 1:
The back cover is made of transparent material specifically at the region where the rear surface design needs to be visible, while maintaining protective coverage. This allows different parts of the back cover to have different properties - transparent for visibility and opaque/protective for other areas, resolving the contradiction between protection and visibility.
2Illumination intensity
If the back cover is made of a transparent material to expose the rear surface design, then the design is visible, but the auxiliary battery cannot be stably coupled to the casing and the casing becomes weak in strength
Solution Approach 1:
The back cover uses a composite structure combining transparent material with reinforcement elements. The transparent portion allows visibility while embedded reinforcement structures (such as ribs or integrated mounting features) provide the necessary mechanical strength and stable coupling for the auxiliary battery, resolving the contradiction between transparency and structural integrity.
3Adaptability or versatility
If the auxiliary battery and mobile device are provided separately, then the device can be charged via auxiliary battery, but a separate charging cable must be additionally provided and it is inconvenient to grasp both items simultaneously
Solution Approach 1:
The auxiliary battery is integrated into the casing structure, merging two previously separate items (battery and device) into a single unified unit. This eliminates the need for separate handling and charging cables, as the battery is already positioned to make direct electrical contact with the mobile device through the casing, resolving the contradiction between charging versatility and ease of operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for the mobile device's rear surface design to be fully visible and protected from external impacts and scratches, with stable and secure integration of the battery assembly, enhancing user satisfaction and protection without the need for additional charging cables.
Implementation Method 1
a battery terminal electrically connected to the casing terminal of the casing assembly to provide a power supply to the mobile device
Implementation Method 2
a back cover provided to block an inner space of the main casing and made of a transparent material
