Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in properly adjusting and comfortably wearing virtual-reality head-mounted displays integrated with audio systems, affecting user experience.
Innovation Solution
A strap system for head-mounted displays featuring a rigid segment and a latching subsystem that couples to a detachable audio system, allowing for secure and adjustable mounting, including a semi-rigid segment to conform to the user's head and a latching mechanism with serpentine springs for easy coupling and decoupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing mounting technologies are used for head-mounted displays, then the device can be worn, but it is difficult to properly adjust and comfortably wear the head-mounted display and integrated audio system
Solution Approach 1:
The mounting system is divided into separate functional segments: a rigid segment for structural support and coupling to the head-mounted display, a semi-rigid segment for conforming to the user's head, and a latching subsystem for secure attachment. This segmentation allows each component to be optimized for its specific function while working together to solve the contradiction between adjustability and secure mounting.
Solution Approach 2:
The latching subsystem incorporates movable latches that can transition between engaged and disengaged states, allowing the system to dynamically adjust between secure mounting and easy removal. The latches move along curved paths defined by the slots in the plate, enabling smooth transitions while maintaining reliable connection during use.
2Adaptability or versatility
If a detachable audio system is added to the head-mounted display, then audio functionality is improved, but the complexity of coupling and securing the audio system increases
Solution Approach 1:
The latching subsystem serves multiple functions: it couples the detachable audio system to the head-mounted display, provides secure retention during use, and enables easy detachment when needed. The same plate and latch mechanism handles both the structural coupling and the security function, reducing overall system complexity despite the added audio functionality.
Solution Approach 2:
The audio system is extracted as a detachable component rather than being permanently integrated into the head-mounted display. This allows the audio functionality to be added or removed based on user needs without increasing the permanent complexity of the base device. The coupling mechanism is designed to handle this extractable component independently.
3Reliability
If a secure latching mechanism is used to attach the audio system, then reliable coupling is achieved, but ease of detachment is reduced
Solution Approach 1:
The plate with slots acts as an intermediary element between the latches and the posts of the audio system. The slots guide the movement of the posts and latches, mediating the interaction between the coupling and retention functions. This intermediary structure allows the latches to engage securely with the posts while still permitting easy release by moving along the defined slot paths.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user experience by providing a secure and adjustable fit for both the head-mounted display and detachable audio subsystem, allowing for comfortable wear and easy detachment without removing the headset.
Implementation Method 1
Each latch of the pair of latches includes a pair of members and a serpentine spring. The pair of members join at a first end and are unconnected at a second end to define the opening. The serpentine spring is coupled to the first end of the pair of members.
