Shell-Integrated Capacitor for Ear-Worn Device Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in developing ear-worn electronic devices is to reduce the size of power management electronics and increase the capacitance of RC circuits while minimizing the form factor, as existing capacitors with small form factors have limited capacitance values and bulky power sources like batteries are difficult to integrate.
Innovation Solution
Incorporating one or more capacitors, including supercapacitors and resistors, directly into the shell of the ear-worn electronic device to form an RC circuit, eliminating the need for a separate circuit board and providing power storage within the shell, using fiber capacitors and resistors to enhance capacitance and reduce size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional capacitors and power management circuits are used, then the device can provide power management functionality, but the device size and form factor increase
Solution Approach 1:
The patent merges the capacitor into the shell structure of the ear-worn device, making the shell itself serve as both structural enclosure and power storage component. This integration eliminates the need for separate power management circuit boards and discrete capacitor components, directly reducing device complexity and weight while maintaining power management functionality
Solution Approach 2:
The shell of the device is designed to serve multiple functions: it provides structural enclosure, acts as a mounting surface for electronics, and incorporates capacitor functionality for power storage and management. This multi-functionality reduces the overall component count and device size
2Quantity of substance
If fiber supercapacitors are used, then capacitance is increased, but manufacturing complexity increases
Solution Approach 1:
The patent transitions from traditional capacitor technologies to fiber supercapacitor technology, representing a significant parameter change in capacitance density. This enables achieving high capacitance values in a compact form factor suitable for ear-worn devices, despite the increased manufacturing complexity of integrating fiber-based components
3Use of energy by moving object
If batteries are used for power storage, then energy capacity is increased, but device size and integration difficulty increase
Solution Approach 1:
The patent extracts the power storage function from traditional battery implementations and repositions it within the shell structure using capacitor technology. This extraction allows for reduced size and simplified integration compared to conventional batteries, while still providing adequate power storage capacity for the device's operational requirements
