Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard-sized in-ear wearable devices are uncomfortable and prone to falling off due to varying user ear shapes and sizes, limiting wearing time and application scenarios.
Innovation Solution
A customized in-ear wearable device with a panel assembly that compactly arranges components like a touchpad and charging device, overlapping their projections to minimize space usage and ensure normal function, while using a customized housing that fits the user's ear shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If components are arranged separately on the panel, then each component has sufficient space for normal operation, but the panel area and device size increase
Solution Approach 1:
The patent merges the manipulation device and charging device into a overlapping spatial arrangement where their orthographic projections partially coincide. This allows both devices to share the same panel area rather than requiring separate dedicated spaces, thereby reducing the total panel area while maintaining operational functionality of both components.
Solution Approach 2:
The patent transitions from a two-dimensional separate layout to a three-dimensional overlapping arrangement. By allowing components to occupy different vertical layers or depths within the same projected area, the design reduces the horizontal panel area requirement while ensuring each component has adequate operational space in its functional dimension.
2Adaptability or versatility
If device size is reduced to improve comfort, then wearing comfort and stability improve, but component arrangement becomes more difficult
Solution Approach 1:
The patent combines multiple functions (manipulation and charging) into a compact overlapping arrangement, reducing the overall device size to improve wearing comfort while maintaining all necessary component functions through intelligent spatial integration rather than simple reduction.
Solution Approach 2:
The patent employs a nested arrangement where the charging device is positioned to overlap with the manipulation device, creating a compact integrated structure. This nesting approach allows smaller device dimensions while accommodating all components within the reduced form factor, improving adaptability to user ears.
3Ease of manufacture
If standard-sized devices are used, then manufacturing is simpler, but wearing comfort deteriorates due to varying ear shapes
Solution Approach 1:
The patent applies local quality by creating customized housings with specific geometric parameters (outer diameter D1, inner diameter D2, height H1) that can be tailored to individual user ear characteristics. This allows standard manufacturing processes to produce customized devices by adjusting local dimensional parameters rather than requiring completely custom manufacturing for each user.

AI summary
The present disclosure relates to an in-ear wearable device and a panel assembly thereof. The panel assembly of the in-ear wearable device includes a panel, a mainboard, a manipulation device, a charging device, a battery, an antenna device, a sound pickup device, a speaker assembly, and a wireless communication module. In a plane perpendicular to the panel or the manipulation device, an orthographic projection of the manipulation device partially overlaps an orthographic projection of the charging device; in a plane where the panel or the manipulation device is located, minimum circumscribed circles of the orthographic projections of the manipulation device and the charging device at least partially overlap each other.
