Solution Overview

Problem

Existing audio and video players lack intuitive navigation tools for skipping, scanning, and scrubbing through content, with no support for variable-rate scrubbing or proportional skipping, limiting user control over playback.

Innovation Solution

A versatile audio and video content playback navigation system with an interactive navigation tool that responds to taps, drags, and swipes, allowing users to skip and scan through content at configurable rates, and play sequentially sampled snippets, enabling precise control over playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing audio and video players provide only basic play/pause buttons and fixed-rate fast forward/rewind, then the device complexity remains low, but the ease of operation deteriorates because users cannot intuitively control playback navigation

Engineering Contradiction:
Improveintuitive playback navigationVSAvoidnavigation tool complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The navigation tool is designed to perform multiple functions through different user interactions: tapping the button plays/pauses content, swiping left skips backward by a first time increment, swiping right skips forward by a second time increment, dragging upward scrubs backward through the timeline, and dragging downward scrubs forward through the timeline. This multi-functionality resolves the contradiction by providing intuitive gesture-based control without requiring multiple separate controls.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The navigation tool implements variable-rate scrubbing where the scrubbing speed dynamically adjusts based on the duration of the drag gesture. Longer drag gestures result in faster scrubbing rates, while shorter drags produce slower rates. This dynamic behavior provides intuitive control matching user expectations while maintaining operational simplicity.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If existing players provide fixed-rate scrubbing only, then the device complexity remains low, but the adaptability deteriorates because users cannot vary the scrubbing speed to match their needs

Engineering Contradiction:
Improvescrubbing rate variabilityVSAvoidscrubbing control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements variable-rate scrubbing by dynamically adjusting the scrubbing speed based on the duration of the user's drag gesture. When a user drags the navigation tool upward or downward, the system calculates the drag duration and adjusts the scrubbing rate proportionally. This allows users to scrub through content at different speeds without requiring separate controls for each rate, resolving the contradiction between adaptability and complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The navigation tool automatically determines the appropriate scrubbing rate based on the user's gesture characteristics without requiring the user to select from predefined options. The system self-adjusts the scrubbing speed based on drag duration, providing adaptive control that responds to user intent without adding interface complexity.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If existing players provide only proportional skipping based on swipe distance, then the ease of operation improves, but the productivity deteriorates because users cannot quickly skip large portions of content

Engineering Contradiction:
Improveproportional skipping controlVSAvoidcontent navigation speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The navigation system segments the skipping function into two distinct modes: proportional skipping for precise navigation and fixed-rate skipping for rapid navigation. Swipe gestures trigger proportional skipping where the skip distance corresponds to the swipe distance, while drag gestures trigger variable-rate scrubbing that can cover larger time increments. This segmentation allows users to choose the appropriate mode for their needs, resolving the contradiction between ease of operation and productivity.

Inventive Principle:
Principle #1Segmentation

AI summary

A versatile audio and video content playback navigation system and processes for versatile navigation of audio and video content during playback are disclosed which enable skipping, scanning (and getting snippets of audio while scanning), and swiping (past ads) through audio (e.g., podcast) and setting precision controlled skip and scan distance parameters. The versatile audio and video content playback navigation system and processes allow users to hear snippets of the audio being skipped, and also enables variably-proportionate amounts of audio to be skipped via a single interactive navigation tool, output as a button, so that users can be much more precise with how much audio and/or video to skip.
