Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If head mounted devices are connected with peripheral devices for operation, then the device can function properly, but the portability and ease of operation deteriorate
Solution Approach 1:
The patent integrates the signal source, control panel, power supply, and wireless connection unit into a control section that is wirelessly connected to the virtual reality helmet. This merging of functions into an integrated control system eliminates the need for external peripheral devices while maintaining full operational capability, thereby improving portability without sacrificing device functionality
Solution Approach 2:
The control section is designed with multi-functionality, incorporating a signal source for video output, a control panel for user interaction, a power supply for energy provision, and a wireless connection unit for peripheral communication. This universal design allows the device to perform multiple functions independently, eliminating the need for separate peripheral devices and enhancing ease of operation
2Device complexity
If the head band is fixed for mounting the virtual reality helmet, then the structure is simple, but the adaptability and user comfort deteriorate
Solution Approach 1:
The head band is designed with rotational capability around the virtual reality helmet, transforming it from a static fixed structure to a dynamic adjustable one. This allows the head band to rotate and adapt to different head shapes and sizes, improving user comfort and adaptability while maintaining relatively simple structural implementation through rotational joints
3Ease of operation
If adjustment mechanisms are added to the head band for better fit, then user comfort improves, but the device complexity increases
Solution Approach 1:
The head band is divided into multiple segments including a first head band and a second head band that can be independently adjusted. This segmentation allows each part to be optimized for specific adjustment functions, providing better user comfort through localized adjustments without requiring complex overall structural changes
4Adaptability or versatility
If external devices are required for operation, then device functionality is comprehensive, but the ease of operation and accessibility to external information deteriorate
Solution Approach 1:
The wireless connection unit acts as an intermediary between the virtual reality helmet and external peripheral devices, enabling communication and data exchange without physical connections. This allows users to access external information and maintain comprehensive device functionality while enjoying the ease of wireless operation and improved accessibility

AI summary
A head mounted device includes a virtual reality helmet, a control section, a transmission line and a head band portion. The head band portion includes a rotatable head band detachably positioned on the virtual reality helmet via a connection mechanism including a catching connection portion and a fixing portion having a main body portion. The catching connection portion is mounted in a counterbore of the rotatable head band and includes a catching fixture, two catching halves, a push button and a first elastic part. A driving portion of the bush button moves upward vertically and drives the action of the two driven portions of two catching halves to open or close two catching portions of the catching halves transversely, and thus perform the connection or detachment with the caught portion on the main body portion of the fixing portion.
