Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If visual perception only is used for VR feedback, then the device structure remains simple, but user immersion and feedback timeliness are reduced
Solution Approach 1:
The patent combines multiple haptic feedback components (vibration motor, temperature control module, pressure feedback mechanism) into the VR device to create multi-sensory feedback. This merging of different feedback modalities enriches the user experience and improves immersion without significantly complicating the overall device architecture.
Solution Approach 2:
The VR device is designed with multi-functional output capabilities, integrating visual display, haptic vibration, temperature control, and pressure feedback into a single system. This allows the device to provide diverse feedback types through unified control, enhancing immersion while maintaining structural efficiency.
2Device complexity
If visual perception only is used for VR feedback, then the device maintains simplicity, but feedback timeliness is reduced
Solution Approach 1:
The patent incorporates a vibration motor that can generate immediate haptic feedback through mechanical vibration. This provides rapid tactile response to user interactions with the virtual environment, significantly improving feedback timeliness compared to visual-only systems.
Solution Approach 2:
The temperature control module can rapidly adjust temperature parameters to provide immediate thermal feedback corresponding to virtual events. This quick parameter change capability enhances feedback timeliness by delivering instantaneous thermal responses to user actions.
3Reliability
If haptic components are added to provide multi-sensory feedback, then user immersion is improved, but device complexity increases
Solution Approach 1:
The patent integrates haptic components within the existing VR device structure, nesting the vibration motor, temperature control module, and pressure feedback mechanism inside the head-mounted display framework. This nesting approach adds multi-sensory capabilities while minimizing external structural additions.
Solution Approach 2:
The patent employs flexible contact interfaces and thin-film heating elements that can be integrated into the VR device's existing shell structure. These flexible components adapt to the device's form factor without requiring bulky additional structures, maintaining a relatively simple overall design.

AI summary
An electronic device includes a fixing device and an output device. The fixing device is provided for, after the electronic device is worn by the user, maintaining a relative positional relationship between the electronic device and the at least one part of the user's body. The output device is provided for, after the electronic device is worn by the user, responding to an obtained control command and performing an operation causing the user to receive haptic feedback from the electronic device based on the relative positional relationship.
