Solution Overview

Problem

Existing wearable devices often have acoustic output ends that are not optimally positioned for effective sound transmission to the user, leading to suboptimal sound quality and user experience.

Innovation Solution

The wearable device incorporates a concave section on the wearing part that depresses downward, positioning the acoustic output end closer to the user's ear, such as near the tragus, and includes a connection section that stabilizes the device on the user's auricle, with adjustable elements for enhanced fit and sound transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the acoustic output end is positioned away from the user's ear, then the device structure is simpler and easier to manufacture, but the sound transmission quality deteriorates

Engineering Contradiction:
Improvedevice structure simplicityVSAvoidsound transmission quality
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent introduces a concave section that creates a three-dimensional depression on the wearing part, moving the acoustic output end closer to the user's ear in a spatial dimension. This dimensional change allows the sound output to be positioned optimally near the ear without complicating the overall device structure, resolving the contradiction between structural simplicity and sound transmission quality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent modifies the geometric parameters of the wearing part by adding a concave section with specific depth and curvature characteristics. This parameter change enables the acoustic output end to be positioned closer to the ear (within 5mm distance), improving sound transmission quality while maintaining manufacturability through standardized geometric features.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If the wearing part is made rigid for stable contact, then the stability improves, but the adaptability to different head shapes deteriorates

Engineering Contradiction:
Improvecontact stabilityVSAvoidfit adaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The wearing part is segmented into multiple functional sections: a connection section for stable contact with the auricle, and a concave section for housing the acoustic output end. This segmentation allows each section to be optimized independently - the connection section provides stability while the concave section provides adaptability through its depression geometry that can accommodate various ear shapes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different sections of the wearing part are given different geometric qualities - the connection section has a geometry optimized for stable contact with the auricle, while the concave section has a depression geometry that adapts to different ear canal positions. This local quality differentiation resolves the contradiction between overall stability and local adaptability.

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If the acoustic output end is positioned closer to the ear, then the sound transmission quality improves, but the device complexity increases

Engineering Contradiction:
Improvesound transmission qualityVSAvoidwearing part structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent merges the acoustic output positioning function with the existing wearing part structure by integrating the concave section directly into the wearing part. This merging eliminates the need for separate positioning mechanisms or additional components, achieving close positioning of the acoustic output end to the ear without increasing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)
