Shock-Mounted Camera for VR Headsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual-reality gaming systems lack an image-capture device capable of tracking a user's physical hand motions and are not shock-mounted to a user-mounted display, leading to limited 'reality' experience and potential camera damage upon impact.
Innovation Solution
A virtual-reality system with a camera shock-mounted to a head-mounted display (HMD) that protrudes outward, using a compressible shock mount to absorb impact and maintain electrical coupling, allowing for increased field of view and precise repositioning while resisting breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is rigidly mounted to the HMD, then the camera maintains stable position and field of view, but the camera is vulnerable to damage upon impact
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a compressible shock mount between the camera and HMD that is designed to compress upon impact, absorbing shock forces before they can damage the camera or dislodge it from its mounting position
Solution Approach 2:
The patent applies dynamics by using a shock mount that transitions from a rigid mounting state during normal operation to a compressed cushioning state upon impact, allowing the mounting system to adapt its mechanical properties based on operational conditions
2Area of stationary object
If the camera protrudes outward from the HMD, then the field of view is maximized, but the camera is more exposed to impact forces
Solution Approach 1:
The compressible shock mount provides beforehand cushioning by being pre-positioned between the camera and HMD to absorb impact forces that would otherwise be directly transmitted to the protruding camera, allowing the camera to maintain its forward-protruding position for optimal field of view while being protected from impact damage
3Reliability
If the shock mount is highly compliant, then the camera is well-protected from impact, but the camera position becomes less precise
Solution Approach 1:
The patent applies local quality by designing the shock mount with differentiated compliance characteristics in different spatial directions, providing high compliance and protection along the impact axis while maintaining tighter constraints and more precise positioning in lateral directions

Function Achieved in This Case
The solution enhances the virtual-reality experience by accurately tracking hand motions and minimizing camera damage during drops, providing an improved sense of reality and durability.
Implementation Method 1
a compressible shock mount mounting the camera on the surface. The shock mount is to retract the camera towards the head-mounted display when compressed
Implementation Method 2
The shock mount comprises an elastic polymer

AI summary
A virtual-reality system includes a head-mounted display, a camera protruding from a surface of the head-mounted display, and a compressible shock mount mounting the camera to the head-mounted display. The shock mount is to retract the camera towards the head-mounted display when compressed. The shock mount protects the camera from damage when the head-mounted display is dropped.
