Charging Attachments/Accumulators TRIZ Cases

Conductive adhesive replaces springs or foam to fix and connect a hearing aid battery, while a coating blocks moisture, earwax, leakage, and corrosion.

An arc-shaped hanging rod replaces soft wire links to keep the earplug stable, improve wearing comfort, and simplify charging and carrying.

A curved-top earbud charging case adds mouse buttons and a sliding lid so earbuds stay easy to access without disrupting grip.

Using an LED as both transmitter and receiver, this case replaces moisture-prone contacts and detects charger placement to suspend hearing functions.

Detecting an unworn state before a specific input enables timely headphone pairing without extra case hardware or unintended lid-triggered actions.

Movement sensors recognize taps, rolls, and shakes on audio accessory cases, reducing user inputs while conserving power.

This case combines camera shooting, on-cabin image viewing, charging, audio playback, and file storage in one earphone cabin.

Dynamic timestamp alignment coordinates internal and external speaker signals to resolve synchronization trade-offs during multi-speaker distribution.

Charging case distributes segmented firmware packages to TWS earphones, resolving compatibility issues across independent audio devices.

A speaker device controller assigns processes to input keys based on whether the unit is stored in a charging case.

Spacing the retention portion from the hook segment widens the structure to lower the center of gravity and prevent dislodging during head movements.

A removable speaker charges within a computing device socket, resolving battery drain and poor sound quality in compact electronics.

Control circuit compares paired earpiece battery levels to distribute audio workload, preventing premature shutdown from voltage discrepancies.

A wireless headset powers RF and baseband circuits directly from an external charger, enabling instant audio output.
