Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a compact hearing device design is used, then the device size is reduced, but battery exchange becomes difficult and design flexibility is limited

Engineering Contradiction:

Improvedevice sizeVSAvoiddesign flexibility

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The battery module is divided into separate components: a battery element and a housing with engagement features. This segmentation allows the battery to be exchanged independently while maintaining the compact overall device structure, resolving the contradiction between small size and battery replaceability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The battery module design with standardized engagement features enables universal compatibility across different hearing device models. The same battery module can be used in various device types (BTE, RIE, etc.), providing design flexibility and adaptability while maintaining compact dimensions

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Volume of moving object

If a compact hearing device design is used, then the device size is reduced, but assembly complexity increases

Engineering Contradiction:

Improvedevice sizeVSAvoidassembly complexity

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The battery module combines the battery element, housing, and engagement features into a single integrated unit. This merging simplifies assembly by reducing the number of separate components that need to be assembled, while still maintaining the compact device size through efficient space utilization

Inventive Principle:

Principle #5Merging (Combining)

3Ease of repair

If independent battery exchange is enabled, then user serviceability is improved, but manufacturing cost increases

Engineering Contradiction:

Improveuser serviceabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Ease of repairVSEase of manufacture

Solution Approach 1:

The battery module is designed with user-friendly engagement and disengagement features that enable end users to perform battery changes themselves without requiring specialized tools or technical expertise. This self-service capability improves user serviceability while avoiding the need for complex manufacturing processes

Inventive Principle:

Principle #25Self-service
