Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotating components in wearable devices, such as head-mounted displays, are limited in their ability to house electronics and connectors, leading to compromised system design when integrating other components.
Innovation Solution
The development of an audio system architecture that allows electronic ports and audio components to rotate with a rotatable housing unit, enabling the simultaneous rotation of external connectors, audio systems, and subsystems without degradation over thousands of rotation cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotating components are designed to house electronics and connectors, then system integration capability is improved, but reliability deteriorates due to degradation over rotation cycles
Solution Approach 1:
The patent implements a dynamic rotation mechanism where the housing unit can rotate between locked and unlocked positions. The rotation indicator provides real-time feedback on the rotation state, enabling the system to adapt its configuration dynamically. This dynamic capability allows the rotating components to maintain reliable electrical connections while achieving versatile system integration, as the rotation can be controlled to specific positions rather than being continuously variable.
Solution Approach 2:
The patent incorporates a rotation indicator that provides feedback on the rotation state of the housing unit. This feedback mechanism allows the system to monitor and control the rotation cycles, ensuring that electrical connections are maintained within reliable parameters. The indicator enables users or control systems to track the number of rotations and prevent excessive cycling that would degrade connection reliability.
2Adaptability or versatility
If multiple components are integrated within a single housing, then design flexibility is improved, but device complexity increases
Solution Approach 1:
The patent divides the device into distinct modular components: a main housing and a rotatable housing unit that can be independently assembled and configured. This segmentation allows each module to be optimized separately while maintaining overall design flexibility. The rotatable housing can be attached or detached as needed, reducing the complexity of integrating multiple components into a single fixed structure.
Solution Approach 2:
The rotatable housing unit serves multiple functions: it can house electronics, contain connectors, provide rotation capability, and offer structural support. By designing this single component to fulfill multiple roles, the patent reduces overall device complexity compared to using separate dedicated components for each function. The universal design of the rotatable housing allows it to adapt to different configuration requirements without increasing structural complexity.
