Removable Power Source Module for Hearing Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing instruments face challenges in efficiently replacing power sources and power regulation circuitry without requiring disassembly, which complicates maintenance and upgrades.
Innovation Solution
The introduction of a removable power source module with a power source, cap, and electrical contacts, which can be affixed to the faceplate and removed without separating the faceplate from the shell, allowing for simple replacement and improved sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the power source is permanently integrated into the hearing instrument housing, then the device structure is simplified and sealing is improved, but replacement of the power source requires disassembly of the housing which complicates maintenance
Solution Approach 1:
The power source module is segmented from the main housing by creating a removable module that can be detached without disassembling the entire device. The module includes the power source and associated circuitry as a separate unit that interfaces with the housing through a standardized connection interface.
Solution Approach 2:
The removable power source module is nested within the housing structure, fitting into a dedicated compartment. The module can be inserted and secured within the housing, allowing it to be contained within the overall device structure while remaining independently replaceable.
2Device complexity
If the power source module is made removable without separating the faceplate from the shell, then maintenance complexity is reduced, but the sealing between power source and housing must be improved
Solution Approach 1:
The sealing interface is pre-configured on both the power source module and the housing before assembly. Gaskets or sealing elements are pre-installed on the module components, ensuring that when the module is inserted, the sealing is automatically established without requiring additional assembly steps or compromising the seal integrity.
3Ease of repair
If the power source module includes integrated power regulation circuitry, then replacement of defective circuitry is simplified, but the module design becomes more complex
Solution Approach 1:
The power regulation circuitry is merged with the power source into a single integrated module. This combination allows the entire power management system to be replaced as one unit, simplifying maintenance while the internal integration manages the complexity within the module itself.
Solution Approach 2:
The power source module is designed as a universal unit that handles multiple functions: power storage, power regulation, and electrical connection. This multi-functionality consolidates what would otherwise be separate components, making replacement simpler while containing the design complexity within a standardized module.
