Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted virtual reality products face issues with head-wearing spacing control, resilience, lifespan, and comfort due to limitations in binding belt and gear rack type locking mechanisms, including poor elasticity, short lifespan, and inconvenient regulation.
Innovation Solution
A head-mounted resilient auxiliary locking mechanism featuring a connecting band with a resilient band and locking module, which provides elastic tension to prevent disengagement and facilitates automatic return to the starting position, enhancing comfort and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If binding belt type locking mechanism is used, then the structure is simple, but the elasticity and comfort are poor
Solution Approach 1:
The patent combines the binding belt type locking mechanism with the gear rack type locking mechanism into a unified structure. The connecting band integrates both the belt-like flexibility and the gear rack engagement features, allowing the system to benefit from both simplicity and elastic resilience simultaneously.
Solution Approach 2:
The connecting band is constructed as a composite structure incorporating elastic resilient bands integrated with the gear rack mechanism. This composite design provides both the structural integrity needed for locking and the elastic properties needed for comfort and automatic return.
2Measurement precision
If gear rack type locking mechanism is used, then head wearing spacing can be controlled, but the lifespan is short due to intertooth jumping
Solution Approach 1:
The resilient band acts as a cushioning element that absorbs shocks and impacts before they can cause damage to the gear teeth. By providing this protective cushioning in advance, the mechanism prevents intertooth jumping and extends the lifespan of the gear rack while maintaining precise spacing control.
3Measurement precision
If gear rack type locking mechanism is used, then spacing regulation is precise, but the operation is inconvenient due to lack of automatic return
Solution Approach 1:
The resilient band provides a periodic restoring force that automatically returns the gear rack to its initial position after each adjustment. This periodic action eliminates the need for manual resetting and makes the spacing regulation process more convenient while maintaining precision.
4Reliability
If resilient band is added to prevent disengagement, then reliability improves, but device complexity increases
Solution Approach 1:
The resilient band is merged with the existing gear rack structure of the connecting band rather than being added as a separate component. This integration allows the system to gain improved engagement stability through the resilient band while minimizing the increase in overall device complexity by reusing existing structural elements.
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
The mechanism offers improved comfort through resilient tensioning, automatic regulation, prevention of intertooth jumping, and extended usage life, while allowing quick adjustment of tightness in virtual reality experiences.
Implementation Method 1
a resilient band connected between the connecting band and the rear housing; when the locking module locks the racks, the resilient band prevents the engaging between the racks and the locking module from loosing; and when the locking module releases the racks, the resilient band drives the racks to return
