Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact compressor assembly is used to provide haptic feedback, then the device size and weight are reduced for wearable applications, but the compressor generates vibration and noise that can interfere with natural hand interaction
Solution Approach 1:
The patent applies vibration cancellation by using a second compressor positioned to generate opposing vibrations that cancel out the harmful vibrations from the first compressor. This converts the harmful vibration effect into a beneficial cancellation mechanism, allowing the compressors to coexist in a compact wearable design without generating disruptive vibrations or noise.
2Device complexity
If multiple components (compressors, valves, desiccant portions) are integrated into a single housing, then device complexity and component count are reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent integrates multiple functional components including compressors, valves, desiccant portions, and pneumatic conduits into a single compressor assembly housing. This merging of components reduces the overall device complexity and component count, making the haptic feedback system more suitable for wearable applications while maintaining functional integrity through careful integration.
3Reliability
If a pneumatic system is used to provide haptic feedback through the glove, then realistic tactile sensation is achieved, but the system requires compressed air supply and moisture control mechanisms
Solution Approach 1:
The patent incorporates desiccant portions within the pneumatic system that automatically absorb moisture from the compressed air without requiring external intervention or complex moisture control mechanisms. This self-service approach maintains reliable haptic feedback quality by preventing condensation and moisture-related issues while minimizing the added complexity of moisture management.

AI summary
A human-computer interface may include a compressor housing, a brake, a multi-channel pneumatic connector, a haptic glove counterpressure assembly, a haptic peripheral assembly, and/or a compressor assembly. The compressor assembly may include a housing, a first compressor, a second compressor, and an outlet portion. The housing defines a first end and a second end opposing the first end, the first compressor is disposed at the first end of the housing and is positioned in a first orientation, the second compressor is disposed at the second end of the housing and is positioned in a second orientation that opposes vibration of the first compressor in the first orientation, the the outlet portion provides compressed air from the compressor assembly.
