Innovation Solution
The Animal Wearable Head Mountable Display (AW-HMD) device, which includes a headset with a ruggedized goggle design, light source, lens array, camera optics, and controls for auditory, olfactory, and tactile data, providing visual cues directly to animals and enabling human viewing of their perspective, with integrated sensors and custom software for mammal-specific visual acuity and other species-specific needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If human-designed HMD devices are used for animals, then visual display functionality is provided, but the device form factor and optical parameters are not suitable for animal anatomy and visual acuity
Solution Approach 1:
The patent applies local quality by customizing specific components of the HMD device for animal use. The optical parameters (lens focal length, display resolution, field of view) are locally optimized to match animal visual acuity and head anatomy, while maintaining the overall HMD device structure. This allows adaptation to animal-specific requirements without completely redesigning the entire system.
Solution Approach 2:
The patent implements parameter changes by adjusting key optical and physical parameters of the HMD device. The display resolution, refresh rate, luminance, and optical focal length are modified to correspond to animal visual capabilities. The head mount structure parameters are also changed to fit animal head shapes, transforming the device from human-optimized to animal-optimized specifications.
2Reliability
If standard HMD devices are adapted for animals, then visual cues can be provided, but image stability and alignment with animal perspective are compromised
Solution Approach 1:
The patent employs feedback mechanisms to maintain image stability and proper alignment. Sensors detect the animal's head position, movement, and eye orientation, providing real-time feedback to the control system. The system automatically adjusts the display content and optical parameters based on this feedback, ensuring the visual cues remain stable and correctly aligned with the animal's perspective during movement.
Solution Approach 2:
The patent replaces manual alignment and mechanical adjustment mechanisms with automated sensor-based systems. Instead of requiring physical adjustment of optical components to match animal perspective, the system uses cameras, accelerometers, and gyroscopes to detect animal orientation and automatically computes the correct display transformation, substituting mechanical complexity with electronic control.
3Measurement precision
If human-optimized optical arrays are used, then display functionality is achieved, but visual acuity optimization for specific animal species is lost
Solution Approach 1:
The patent applies parameter changes by adjusting optical display parameters based on species-specific visual acuity data. For each animal species, the system modifies display resolution, pixel density, field of view angle, and luminance levels to match that species' visual capabilities. This allows the same HMD platform to be optimized for different species (dogs, cats, horses) by changing software parameters and optical configurations.
Solution Approach 2:
The patent implements universality by designing a multi-functional HMD system that can serve multiple animal species. The device incorporates adjustable optical parameters and configurable display settings that can be adapted to match the visual requirements of different species, making a single device design versatile enough to accommodate dogs, cats, horses, and other animals with varying visual acuity.
