Innovation Solution
The development of head-worn computing systems that include adjustable ear horn assemblies, rotatable temple and ear horn sections for secure closure, an adjustable nose bridge, and removable speaker assemblies, along with a stiff ear horn with a touch pad for counteracting forces, to ensure comfort and stability during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the head worn computer includes adjustable ear horn assemblies and stiff members extending behind the ear, then the stability and secure fit is improved, but the weight and device complexity increase
Solution Approach 1:
The patent employs stiff members extending behind the ear to create counterbalancing forces that offset the weight of the display portion positioned on the forehead. This counterweight approach distributes the mechanical load more evenly across the head, improving stability without requiring excessive overall weight in any single component.
Solution Approach 2:
The head worn computer is divided into distinct functional segments: a display portion mounted on the forehead, temple portions extending along the sides, and ear horn assemblies positioned at the ears. This segmentation allows each component to be optimized independently for its specific function while collectively achieving overall stability.
2Adaptability or versatility
If the head worn computer includes adjustable ear horn assemblies and rotatable temple sections, then the adaptability and secure fit are improved, but the device complexity increases
Solution Approach 1:
The patent incorporates rotatable temple sections and adjustable ear horn assemblies that can be dynamically repositioned to accommodate different head shapes and sizes. These dynamic adjustment mechanisms allow the device to adapt to various users while maintaining a relatively simple overall structure through the use of straightforward rotational and sliding joints.
Solution Approach 2:
The temple portions serve multiple functions: they provide structural support, enable adjustment for different head sizes through rotation, and connect the display portion to the ear horn assemblies. This multi-functionality reduces the need for separate components, thereby managing device complexity while enhancing adaptability.
3Weight of moving object
If the head worn computer uses a lightweight and compact design, then the comfort is improved, but the structural strength and stability may be compromised
Solution Approach 1:
The patent utilizes composite material construction for the temple portions and ear horn assemblies, combining materials with different properties to achieve optimal strength-to-weight ratios. This allows the structure to maintain adequate strength and stability while keeping the overall weight low for user comfort.
Solution Approach 2:
The ear horn assemblies are designed to follow the natural curvature of the ear, distributing contact forces more evenly across the ear structure. This curved geometry enhances structural efficiency, allowing thinner and lighter components to achieve the same load-bearing capacity as heavier straight structures.
