Pivoting Headset Bracket for Adjustable Foot Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted displays lack adjustable maximum spacing between feet, making them unsuitable for users with varying head sizes, as they cannot be intentionally adjusted to fit different head sizes effectively.
Innovation Solution
A wearable device with pivoting modules comprising a first and second bracket, where the second bracket is pivotally coupled to the first and features a positioning member with slots and a stopper, allowing the maximum outreaching volume to be adjusted by inserting an inserting member into different slots, thereby changing the maximum spacing between the feet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the maximum spacing between feet is fixed, then the structure is simple, but the device cannot be adjusted to fit different head sizes
Solution Approach 1:
The patent implements adjustability by making the bracket structure dynamically configurable through pivoting motion. The second bracket is pivotally coupled to the first bracket, allowing the maximum spacing between feet to be adjusted by rotating the second bracket relative to the first bracket around a pivot axis. This dynamic adjustment mechanism resolves the contradiction by enabling adaptability to different head sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent divides the bracket into multiple separable components: a first bracket fixed to the frame, a second bracket fixed to the foot, and a pivoting connection between them. This segmentation allows independent adjustment of the second bracket's position while keeping the first bracket stable, thereby achieving adjustability without significantly increasing overall structural complexity.
2Adaptability or versatility
If the maximum spacing between feet is adjustable, then the device can fit different head sizes, but the structure becomes complex
Solution Approach 1:
The patent implements adjustability by making the bracket structure dynamically configurable through pivoting motion. The second bracket is pivotally coupled to the first bracket, allowing the maximum spacing between feet to be adjusted by rotating the second bracket relative to the first bracket around a pivot axis. This dynamic adjustment mechanism resolves the contradiction by enabling adaptability to different head sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent divides the bracket into multiple separable components: a first bracket fixed to the frame, a second bracket fixed to the foot, and a pivoting connection between them. This segmentation allows independent adjustment of the second bracket's position while keeping the first bracket stable, thereby achieving adjustability without significantly increasing overall structural complexity.
3Adaptability or versatility
If a pivoting mechanism is added to adjust spacing, then adaptability improves, but the device complexity increases
Solution Approach 1:
The patent employs a simple pivoting mechanism where the second bracket is pivotally coupled to the first bracket. This pivotal connection allows the second bracket to rotate relative to the first bracket around a pivot axis, enabling adjustment of the maximum spacing between feet. The mechanism achieves adaptability through this single degree of freedom pivoting motion while keeping the structural complexity relatively low.
Solution Approach 2:
The pivoting mechanism is pre-configured with predetermined pivot positions that correspond to different maximum spacing settings. This preliminary arrangement of pivot positions allows users to directly select the desired spacing without requiring complex adjustment procedures, thereby improving adaptability while controlling the complexity of the adjustment mechanism.

AI summary
A wearable device includes a frame, two feet, and two pivoting modules. Each of the pivoting modules includes a first bracket fixedly connected to the frame, and a second bracket fixedly connected to one of the feet and pivotally coupled to the first bracket. The second bracket includes a positioning member and an inserting member. The positioning member is located in the first bracket, and the positioning member includes a plurality of slots. The inserting member is switchably inserted into one of the slots for adjusting a maximum outreaching volume from the frame to the feet.
