Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The helix hearing instrument's limited capabilities and battery life are constrained by the size of its electronics assembly and available space, hindering the addition of new functions and extended battery life.
Innovation Solution
A behind-the-ear accessory module is introduced, which houses additional components like batteries, a directional microphone, and wireless capabilities, connected to the helix hearing instrument via an interconnecting cable and electronics pod, enhancing functionality and battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronics assembly size is increased to provide additional capabilities and longer battery life, then the hearing instrument's functionality and battery life are improved, but the device becomes larger and more complex
Solution Approach 1:
The hearing instrument is divided into two separate modules: a compact helix hearing instrument containing the receiver and a behind-the-ear accessory module containing the electronics assembly, battery, and additional components. This segmentation allows each module to be optimized independently - the helix instrument remains small for comfort while the accessory module provides extended functionality and power.
Solution Approach 2:
A cable connection serves as an intermediary between the helix hearing instrument and the behind-the-ear accessory module, enabling wireless and wired communication while allowing flexible positioning of the electronics assembly away from the ear canal.
2Duration of action of stationary object
If the battery size is increased to extend battery life, then the hearing instrument's operational duration is improved, but the device volume and weight increase
Solution Approach 1:
The battery is segregated into the behind-the-ear accessory module rather than being integrated into the helix hearing instrument. This allows the battery to be sized for extended operation while keeping the ear canal component compact and lightweight.
Solution Approach 2:
The battery and electronics assembly are positioned in a different spatial location (behind the ear) rather than confining all components within the ear canal, utilizing available space in a different dimensional region.
3Adaptability or versatility
If additional components are added to enhance functionality, then the hearing instrument's features are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Additional components such as the directional microphone, wireless transceiver, and processing unit are consolidated into a separate accessory module that can be manufactured independently using established behind-the-ear hearing instrument manufacturing processes, then integrated with the helix receiver through standardized cable connections.
