Multifunction Button for Audio Storage Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio storage devices require multiple single-function buttons for various operations, which can be cumbersome and inefficient, whereas the goal is to control an audio storage device with a single multifunction button that can record, lock, unlock, transfer, and play back audio recordings based on different button interactions.
Innovation Solution
A single multifunction button on an audio storage device performs multiple functions by varying the duration and pattern of button presses, such as tapping, double tapping, holding for different thresholds, to initiate recording, playback, transfer, locking, and unlocking of audio recordings, with audible cues guiding user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple single-function buttons are used for various operations, then each button has a dedicated function, but the device complexity and ease of operation deteriorate due to the number of buttons required
Solution Approach 1:
The patent implements a single button that can perform multiple functions (recording, playback, transferring, locking, unlocking) by detecting different press patterns including tap count, hold duration, and press intensity. This multi-functional button design directly applies the universality principle to reduce the total number of physical buttons while maintaining comprehensive operational capability.
Solution Approach 2:
The button system dynamically adapts its function based on the detected press pattern characteristics. The controller interprets various interaction modes (single tap, double tap, long press, hard press) to dynamically assign different operations, making the static button physically dynamic in its functional output.
2Adaptability or versatility
If multiple single-function buttons are used for various operations, then each operation has a dedicated control, but the ease of operation worsens due to the cumbersome nature of multiple buttons
Solution Approach 1:
By consolidating multiple operations into a single button interface, the patent improves ease of operation. Users can access all essential functions (record, play, transfer, lock, unlock) through one familiar interaction point rather than navigating multiple separate buttons, enhancing user convenience while preserving full operational capability.
Solution Approach 2:
The system uses periodic or repeated tap actions (single tap, double tap, multiple taps) as distinct command inputs. This periodic interaction pattern provides intuitive and easy-to-learn gestures that improve ease of operation compared to requiring users to locate and press different buttons for different functions.
3Device complexity
If a single multifunction button is used, then device complexity is reduced, but the difficulty of detecting and measuring worsens due to distinguishing different press patterns
Solution Approach 1:
The system incorporates feedback mechanisms where the controller continuously monitors button press characteristics (duration, intensity, repetition) and provides audible cues to confirm detected patterns. This feedback loop helps verify correct pattern recognition and allows the system to adaptively distinguish between different press patterns more reliably.
Solution Approach 2:
The patent detects different press patterns by measuring changes in physical parameters including press duration, press intensity (force), and tap frequency. By monitoring these parameter variations, the system can reliably distinguish between different user intentions (tap vs. hold, soft press vs. hard press) without increasing physical button complexity.
4Device complexity
If different button press patterns are used for different functions, then functionality is consolidated in one button, but the ease of operation worsens due to learning multiple interaction patterns
Solution Approach 1:
The system uses intuitive periodic actions (taps) that follow natural user behavior patterns. Single tap, double tap, and multiple tap sequences are universally understood gestures that reduce learning curve compared to arbitrary button combinations, making the consolidated single-button interface easier to operate despite multiple functions.
Solution Approach 2:
Audible feedback cues are provided to confirm which function is activated by each press pattern. This immediate feedback helps users learn and remember the mapping between press patterns and functions more quickly, reducing the operational learning burden while maintaining the benefits of a simplified single-button control structure.

AI summary
Aspects of the present invention enable a storage device (e.g., a recordable book, toy, computing device) to be controlled with a single control button that performs multiple functions. Different interactions with the button produce a different control input. In one aspect, the storage device is an audio recording device that can record, lock, unlock, transfer to a separate storage device, or play back one or more audio recordings. These five functions (i.e., recording, locking, unlocking, transferring, and playing back) are initiated or facilitated by depressing a single button located on the audio storage device for different lengths of time or in different patterns. Audio recordings may be played in response to user interactions with the button to help the user interact with the button properly and warn the user of action that is about to be taken.
