Universal Cradle with Stepped Cavity for Multi-Format Music Players
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio devices with cradles for portable music players are often proprietary, limiting compatibility with different music player sizes and shapes, requiring additional cables for power and audio connections when unsupported players are used.
Innovation Solution
A cradle system with a stepped cavity and power port that supports multiple digital music players of varying sizes, providing power through a connector and allowing for flexible audio connections, ensuring compatibility and power supply across different devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a proprietary cradle/jack system is used for a specific music player, then the connection and power supply are integrated and simple, but the system cannot support other music players of different sizes and shapes
Solution Approach 1:
The cradle is designed with a universal cavity and integrated jack system that can accommodate multiple music player models simultaneously. The cavity includesledges and support surfaces that adapt to different device dimensions, while the integrated jack provides both audio connection and power supply through a single interface, eliminating the need for separate power cables for supported devices.
Solution Approach 2:
The cradle structure is segmented into functional zones: a cavity for device placement, ledges for mechanical support, and an integrated jack for electrical connection. This segmentation allows each component to be optimized for its specific function while working together to support various music player form factors.
2Ease of operation
If a non-supported music player is used with the cradle, then the player can be connected via audio cables, but additional power cables are required and the player cannot be held securely in the cradle
Solution Approach 1:
The cradle integrates the audio jack and power supply functionality into a single unified interface. When a compatible music player is placed in the cradle cavity, both audio connection and power supply are established simultaneously through the integrated jack, eliminating the need for separate power cables and simplifying the connection process.
3Adaptability or versatility
If the cradle cavity is designed to fit the largest music player, then larger players can be supported, but smaller players may not be held securely without additional support structures
Solution Approach 1:
The cradle cavity incorporates ledges at specific locations that provide localized support for different music player sizes. The ledges are positioned to accommodate the varying dimensions of different players, with the cavity overall sized to fit the largest player while the ledges provide additional support points for smaller devices, eliminating the need for complex adjustable support structures.

AI summary
An audio device supports a variety of digital music players and includes a cradle that physically holds any of a plurality of digital music players. A power port on the audio device provides power to a selected one of the digital music players, through a cable that is specific to the selected digital music player through a cable that connects between the power port and the selected digital music player while the selected digital music player is held within the cradle.
