Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head mounted devices require manual adjustment for fit, leading to user discomfort and instability due to incorrect sizing, and the adjustment process is time-consuming.
Innovation Solution
A head mounted device with an elongate member that expands and contracts to conform to the user's head, featuring an elongate member control mechanism and retaining mechanism to simplify adjustment, ensuring a secure and comfortable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If manual adjustment is used for head mounted device fit, then device stability can be improved, but user comfort deteriorates due to incorrect sizing
Solution Approach 1:
The patent applies dynamics by making the elongate member adjustable and movable rather than fixed. The elongate member can be extended or retracted to accommodate different head sizes, transforming a static structure into a dynamic one that adapts to user needs, thereby resolving the contradiction between stability and comfort.
Solution Approach 2:
The patent changes the length parameter of the elongate member to fit different users. By allowing the elongate member to be adjusted in length, the device can maintain stability while adapting to various head sizes, thus improving user comfort without sacrificing device stability.
2Stability of the object's composition
If manual adjustment is used for head mounted device fit, then device stability can be improved, but adjustment time increases making the process time-consuming
Solution Approach 1:
The patent enables self-service adjustment through the adjustable elongate member that users can easily extend or retract themselves. This eliminates the need for complex manual adjustment mechanisms or assistance from others, reducing adjustment time while maintaining device stability.
Solution Approach 2:
The dynamic nature of the adjustable elongate member allows for quick size changes without complex procedures. Users can rapidly adjust the device to their head size, significantly reducing the time required for setup while ensuring stable device positioning.
3Manufacturing precision
If fixed size head mounted device is used, then manufacturing precision can be improved, but adaptability deteriorates due to inability to fit various head sizes
Solution Approach 1:
The patent transforms the fixed-size device into an adaptable one by introducing an adjustable elongate member. This dynamic component allows the same manufactured device to fit various head sizes, maintaining manufacturing precision while achieving broad adaptability across different users.
Solution Approach 2:
The adjustable elongate member enables a single device design to serve multiple functions - accommodating different head sizes and user preferences. This universality allows the device to maintain precise manufacturing specifications while adapting to diverse user needs, eliminating the need for multiple fixed-size variants.
