Adjustable Hand Controller Strap via Slide Rail Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality hand controllers often interfere with users due to varying palm sizes, affecting user experience as the fixed hand strap can hinder button pressing.
Innovation Solution
A hand controller assembly featuring a slide rail and detachable strap with a metal member and sliding block, allowing adjustable connection points to accommodate different palm sizes by moving the metal member along the slide rail, which restricts movement with a limiting portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hand strap is fixed to the hand controller, then the hand controller can be securely held, but the strap interferes with users of different palm sizes when pressing buttons
Solution Approach 1:
The patent applies the dynamics principle by making the strap connection position adjustable rather than fixed. The sliding block mechanism allows the metal member to move along the slide rail, enabling users to dynamically adjust the strap's connection point on the hand controller to suit their palm size, thus resolving the conflict between secure holding and button pressing comfort
Solution Approach 2:
The patent segments the connection system into detachable components: a sliding block on the strap, a slide rail on the hand controller, and a metal member that connects them. This segmentation allows the strap connection position to be independently adjusted without affecting the overall structure, enabling users to optimize the connection point for their specific needs
2Adaptability or versatility
If the strap connection position is fixed, then the structure is simple, but it cannot accommodate users with different palm sizes
Solution Approach 1:
The patent transforms the static fixed connection into a dynamic adjustable connection using a sliding block mechanism. The metal member can slide along the slide rail to different positions, providing adaptability for various palm sizes while maintaining a relatively simple overall structure through the use of straightforward mechanical components
Solution Approach 2:
The patent introduces an intermediary mechanism (the sliding block and slide rail system) between the strap and the hand controller. This intermediary allows for position adjustment without requiring complex reconfiguration of the entire strap system, achieving adaptability through a dedicated adjustment mechanism that adds minimal complexity

AI summary
A hand controller assembly including a hand controller, a slide rail and a strap. The hand controller has a top and a bottom opposite to each other. The slide rail is disposed at the top and has an entrance and a limiting portion adjacent to the entrance. The strap is detachably assembled to the slide rail and the bottom. The strap includes a body and a metal member. The metal member is assembled to one end of the body. The metal member has a sliding block. The sliding block is adapted to be detachably assembled to the slide rail via the entrance along a direction. The sliding block is adapted to move along the limiting portion. The limiting portion restricts the movement of the sliding block along the direction.
