Wireless Power Bank Packaging for Retail Charging Demo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power banks require direct contact for charging, which can be inconvenient and may not allow for efficient wireless charging of portable devices when packaged for retail display, as they consume battery power without providing functionality testing.
Innovation Solution
A power bank system with a packaging container and a power bank that includes a primary coil and sensor, allowing for wireless charging of portable devices by positioning the power bank within the container such that the coil and sensor are proximate to an external surface, enabling induction charging and minimizing battery consumption for sensor operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the power bank is positioned within the packaging container with the coil and sensor proximate to the external surface, then wireless charging functionality is enabled and battery power consumption is reduced, but the device complexity and packaging structure complexity increase
Solution Approach 1:
The packaging container is merged with the wireless charging functionality by integrating the external receiving surface and coil structure into the container itself. The container serves dual purposes: protecting the power bank during transport and enabling wireless charging when the power bank is positioned within it, thereby eliminating the need for separate charging infrastructure and reducing overall system complexity.
Solution Approach 2:
The packaging container is designed with multi-functionality, serving both as protective packaging and as a wireless charging station. The external receiving surface on the container can detect and charge portable devices placed on it, allowing the same structure to fulfill multiple roles throughout the product lifecycle from retail display to post-purchase charging.
2Ease of operation
If the power bank requires direct contact for charging, then the charging mechanism is simple and reliable, but the ease of operation and user convenience are reduced
Solution Approach 1:
The mechanical direct contact charging system is replaced with a wireless electromagnetic induction system. The coil generates an electromagnetic field that transfers power to the portable device without physical contact, eliminating the need for plugging and unplugging cables, thereby improving user convenience while maintaining charging reliability through sensor-activated control.
Solution Approach 2:
The wireless charging system incorporates automatic detection and activation through sensors that detect the presence of a portable device on the external receiving surface. The system automatically initiates charging without user intervention, adjusts power delivery based on device requirements, and eliminates the need for manual connection steps, thereby enhancing ease of operation.
3Reliability
If the sensor operates using the power bank's battery power, then the system is simpler with fewer components, but the battery power is consumed without providing functional testing benefit
Solution Approach 1:
The power supply system is segmented into two independent sources: the power bank's battery for power delivery functions and a separate power source for sensor operation. This segmentation allows the sensor to operate continuously during retail display and functionality testing without depleting the power bank's battery, while still enabling the power bank to charge portable devices when needed.
Solution Approach 2:
A separate power source acts as an intermediary to supply power specifically to the sensor system. This intermediary power source enables the sensor to perform its detection and testing functions independently, preventing battery power consumption while maintaining the ability to test and demonstrate wireless charging functionality to consumers before purchase.

Function Achieved in This Case
Enables efficient wireless charging of portable devices without direct contact and conserves battery power by using a separate power source for the sensor, allowing consumers to test the power bank's functionality before purchase.
Implementation Method 1
The power bank is configured to deliver power from the battery to the portable device wirelessly via the primary coil and through the external receiving surface

AI summary
A power bank system includes a packaging container and a power bank. The packaging container defines an internal cavity and has an external receiving surface. The power bank has a battery, a primary coil, and a sensor. The power bank is positioned within the internal cavity such that the primary coil and the sensor are disposed proximate to an opposing side of the external receiving surface. The external receiving surface is configured to receive a portable device. The power bank is configured to deliver power from the battery to the portable device wirelessly via the primary coil and though the external receiving surface in response to the sensor detecting the portable device being positioned proximate the external receiving surface.
