Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If actuators are added to provide tactile stimulation, then user sensory experience is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple actuators (voice coils and vibrating motors) into a single head-mounted display device, integrating tactile stimulation functionality with the existing visual display system. This merging approach provides multi-sensory experience while consolidating components to manage complexity.
Solution Approach 2:
The head-mounted display is designed to perform multiple functions: visual display through the ocular optical system and tactile stimulation through actuators. This multi-functionality allows a single device to provide both visual and tactile sensory feedback, enhancing overall user experience.
2Adaptability or versatility
If multiple actuators are integrated into the head-mounted display, then tactile feedback capability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the actuator system into distinct components (voice coils and vibrating motors) that can be independently manufactured and then assembled into the head-mounted display. This segmentation allows for specialized manufacturing of each actuator type while simplifying the overall assembly process.
Solution Approach 2:
The patent introduces an actuator support structure that serves as an intermediary component, holding and positioning multiple actuators within the head-mounted display. This mediator structure simplifies manufacturing by providing a standardized platform for actuator installation and integration.
