Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional artificial reality headsets are designed with sufficient battery capacity and performance components, then performance and battery life are improved, but weight and size increase making the device uncomfortable to wear
Solution Approach 1:
The headset is divided into two separate frame plates: an electronics-holding frame plate that contains all electrical components (battery, PCB, antenna, projector) and a frame backplate that attaches to the user's head. This segmentation allows the heavy electronics to be concentrated in one module, potentially optimizing weight distribution and reducing overall headset size while maintaining performance.
Solution Approach 2:
Multiple electrical components are nested within the electronics-holding frame plate cavity. The PCB is positioned within the cavity, the antenna is attached to the plate, and the projector is mounted on the plate. This nesting approach consolidates components into a compact arrangement, reducing overall device size and weight while maintaining full functionality.
2Ease of manufacture
If off-the-shelf components are used in traditional headsets, then device assembly is simplified, but the device size and weight increase compromising comfort
Solution Approach 1:
Multiple standard components (PCB, antenna, projector, battery) are merged into a single integrated electronics-holding frame plate assembly. This consolidation creates a compact module that reduces overall device size and weight while maintaining ease of manufacture through standardized component interfaces and a unified attachment structure to the frame.
3Stability of the object's composition
If electrical components are distributed throughout the headset structure, then structural stability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The headset structure is segmented into distinct functional modules: the electronics-holding frame plate contains all electrical components, while the frame backplate provides structural support and user interface elements. This clear segmentation simplifies manufacturing by allowing each module to be assembled and tested independently before final integration, reducing overall device complexity while maintaining structural stability.

AI summary
An augmented-reality headset comprises one or more lenses within a housing of the artificial-reality headset, and at least one of the one or more lenses is configured to present an augmented reality user interface to a wearer of the artificial-reality headset. The augmented-reality headset comprises one or more flexures coupled to a lens of the one or more lenses, and each respective flexure of the one or more flexures is configured to: (i) compress when a force is applied to the housing, thereby reducing a load received at the lens, and (ii) be coupled to the lens to orient the lens to have a predetermined orientation within the housing.
