Outdoor Musical Instrument with QR Code and Mobile Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor musical instruments lack interactive features and usability enhancements, such as compatibility with mobile devices for interactive functions and convenient viewing angles, which limits their educational and entertainment value in outdoor settings.
Innovation Solution
Design of outdoor musical instruments with integrated machine-readable codes (e.g., QR codes) that enable interactive features on mobile devices, such as song sheets, training tools, and recording options, along with a stand that supports mobile devices at a suitable angle for viewing and video recording, enhancing user interaction and experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If outdoor musical instruments are designed without mobile device integration, then the device complexity is reduced, but the interactivity and educational value are limited
Solution Approach 1:
The patent uses a mobile computing device as an intermediary to provide interactive features. The instrument includes a machine-readable code that, when scanned by a mobile device, enables additional functions such as song sheets, training tools, and recording capabilities. This allows the instrument to gain enhanced interactivity without the complexity being built directly into the instrument structure.
2Ease of operation
If a stand is added to support mobile devices, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The stand is designed to automatically position the mobile computing device at optimal viewing angles and recording positions without requiring manual adjustment. The stand includes a camera mount that self-aligns to provide the camera with a field of view conducive to video recording, eliminating the need for complex adjustment mechanisms while improving ease of operation.
3Ease of operation
If the stand positions the device for optimal viewing, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The stand is designed with asymmetric geometry that naturally guides the mobile device into the correct position and angle. Rather than requiring precise manufacturing tolerances, the stand uses its asymmetric shape to physically constrain the device at the optimal viewing angle and recording position, reducing manufacturing precision requirements while maintaining ease of operation.

AI summary
An outdoor musical instrument, such as may be installed in a playground or other public outdoor recreational area, includes a machine-readable code. The code is readable by a mobile computing device, such as a smartphone or tablet, and, when read, furnishes the device with one or more interactive functions relating to the musical instrument and that provide enhanced play opportunities. The musical instrument may also include a stand configured for a user to place the device after reading the code in order to utilize the interactive functions while playing the instrument.
