Head-Mounted Display Counterweight Brackets for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display devices suffer from instability due to concentrated weight at the front, leading to easy displacement during dynamic movements.
Innovation Solution
A head-mounted display device design featuring a front-end assembly, support arms, counterweight parts, and adjustable brackets that distribute weight evenly across the back of the user's head, allowing for adjustable counterweight placement and improved stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the weight is concentrated on the front assembly, then the device structure is simple, but the wearing stability deteriorates
Solution Approach 1:
The patent introduces counterweight parts that slide along the support arms to balance the weight distribution. These counterweight parts are positioned on the rear side of the head-mounted device to offset the front-heavy weight concentration, thereby improving wearing stability without significantly complicating the overall device structure.
Solution Approach 2:
The counterweight parts are designed to be slidable along the support arms, allowing dynamic adjustment of the counterweight position. This enables the device to adapt to different head sizes and shapes, optimizing weight distribution and wearing stability for each user while maintaining a relatively simple device structure.
2Device complexity
If the brackets are fixed in position, then the device structure is simple, but the adaptability to different head sizes deteriorates
Solution Approach 1:
The brackets are designed to slide along the support arms to different positions, allowing adjustment to accommodate various head sizes and shapes. This dynamic positioning capability enables the device to adapt to different users without requiring multiple fixed-size models, while the sliding mechanism remains relatively simple in structure.
Solution Approach 2:
The slidable bracket design allows a single device model to serve multiple head sizes and shapes, making the device universal rather than requiring separate models for different head dimensions. This multi-functional capability is achieved through a relatively simple sliding adjustment mechanism.

AI summary
A head-mounted display device includes a front-end assembly, a plurality of support arms, a plurality of counterweight parts and a plurality of brackets. The plurality of support arms are respectively connected to the front-end assembly. The plurality of counterweight parts are respectively slidably arranged to the plurality of support arms and away from the front assembly. The plurality of brackets are respectively connected to the plurality of counterweight parts and used for contacting the head of the user. The brackets are separated from each other. Each of the brackets has an upper part and a lower part. The upper parts of the brackets are adapted to support the upper part of the back of the user's head. The lower parts of the brackets are adapted to support the lower part of the back of the user's head.
