Modular Wireless Charging Cradle for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional docking stations for mobile devices are inflexible and require replacement when users upgrade to new devices, as they are often designed specifically for a particular device and lack compatibility with different models, leading to unnecessary accessory replacement.
Innovation Solution
A modular docking system with a removable wireless charging unit that can be used across various devices, featuring a self-contained wireless charger with an internal power supply and interchangeable components, allowing for customization and reuse of accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If docking stations are designed specifically to match the contour and shape of a particular mobile device, then the device fit and security within the docking station is improved, but the adaptability to different mobile devices deteriorates
Solution Approach 1:
The docking station is designed with a universal interface and standardized mounting mechanisms that can accommodate multiple mobile device models and types. The cradle structure includes adjustable components and universal connection interfaces that maintain secure holding while being compatible across different device form factors, eliminating the need for device-specific docking stations.
2Duration of action of stationary object
If docking stations are designed for long-term use with a single device, then the durability and stability are improved, but the flexibility to accommodate new devices deteriorates
Solution Approach 1:
The docking station incorporates dynamic and adjustable components including reconfigurable cradle positions, adjustable clamping mechanisms, and modular attachments that can be reconfigured to suit different device types. This allows the stationary docking station to adapt its structure over time while maintaining durability, accommodating device upgrades without replacement.
3Reliability
If users purchase a new docking station with each new mobile device, then the compatibility and optimized performance for each device is improved, but the loss of resources and increased cost deteriorates
Solution Approach 1:
The docking station design allows users to retain and reuse the main docking unit when upgrading mobile devices. Only the mobile device itself needs replacement, while the docking station, cradle, and accessories can be recovered and continued to be used with new devices, significantly reducing accessory waste and replacement costs.
4Reliability
If conventional docking stations use wired charging connections, then the charging reliability is improved, but the complexity of wire management and potential for damage deteriorates
Solution Approach 1:
The patent extracts the charging connection from external wires and integrates it directly into the docking station structure. The charging contacts are built-in and automatically engage when the mobile device is placed in the cradle, eliminating the need for separate wire management while maintaining reliable charging connections.
