HMD Wearable Member with Hinge and Rear Band Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Head Mounted Displays (HMDs) face challenges in providing a simple and convenient mechanism for users to adjust the position and fit of the display body on their head, leading to increased manufacturing costs and difficulty in fine adjustments for sliding or tilting.
Innovation Solution
The HMD features a wearable member with a front band part, hinge members, and a rear band part that includes slide rails and a rotation gear system, allowing for easy adjustment and secure fitting by tightening or loosening the wearable member, enabling smooth sliding and tilting of the display body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complicated structure is employed to enable body movement and adjustment, then the HMD can achieve stable fitting and adjustment functionality, but the manufacturing cost increases and fine adjustment becomes difficult
Solution Approach 1:
The wearable member is divided into distinct functional components: front band part for positioning, hinge members for pivoting motion, rear band part for securing, and adjustment members for tension control. Each segment performs a specific function, simplifying the overall design while maintaining adjustment capability and stable fitting.
2Reliability
If a complicated structure is employed to enable body movement and adjustment, then the HMD can achieve stable fitting and adjustment functionality, but the manufacturing cost increases
Solution Approach 1:
By segmenting the wearable member into standardizable components (front band part, hinge members, rear band part, adjustment members), each part can be manufactured independently using simpler processes and then assembled, reducing overall manufacturing complexity and cost while ensuring reliable assembly.
Solution Approach 2:
The hinge members serve multiple functions: they connect the front and rear band parts, enable pivoting motion of the body, and provide a mounting structure for the adjustment members. This multi-functionality reduces the total number of components needed, simplifying manufacturing.
3Reliability
If a complicated structure is employed for wearable member adjustment, then the HMD can achieve stable fitting, but fine adjustment for sliding or tilting becomes difficult
Solution Approach 1:
The hinge members enable dynamic pivoting motion of the body relative to the front band part, allowing users to easily adjust the tilting angle. The adjustment members provide dynamic tension control, enabling fine adjustment of the wearable member's fit by sliding along the front band part.
