Wrist Rest with Vibration Isolation for Stable Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrist rest designs with haptic feedback either cause discomfort or interfere with gaming input devices due to direct vibration of the housing or cushion, leading to instability and discomfort.
Innovation Solution
A wrist rest design featuring a base structure with flexible supports isolating a vibration assembly, which is concealed beneath a cushion, allowing for subtle haptic feedback without direct contact, using a lubricating layer to minimize vibration loss and facilitate movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the vibration assembly is isolated from the base structure using flexible supports, then the housing remains stable, but vibration energy may be lost
Solution Approach 1:
The flexible supports are designed with specific material and structural parameters that allow them to be compliant enough to isolate vibrations from the housing while maintaining sufficient stiffness to transmit vibration energy effectively to the cushion assembly.
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
Delivers refined and subtle haptic feedback that minimizes discomfort and interference with gaming input devices, ensuring stability and comfort during use.
Implementation Method 1
The at least two flexible supports are configured to isolate the base structure from a vibrating motion of the vibration assembly
Implementation Method 2
The lubricating layer may be configured to minimise vibration losses of the vibration member of the vibration assembly and facilitate the relative movement between the vibration member of the vibration assembly and the cushion of the cushion assembly

AI summary
The wrist rest may include a base structure; at least two flexible supports extending from the base structure; a vibration assembly supported on the at least two flexible supports in a manner such that the vibration assembly may be spaced apart from the base structure; and a cushion assembly including a cushion disposed over the vibration assembly in a manner so as to conceal the vibration assembly between the base structure and the cushion. The cushion may be secured to the base structure. The at least two flexible supports may be configured to isolate the base structure from a vibrating motion of the vibration assembly. A surface of the vibration assembly directed towards the cushion assembly may move relative to a corresponding surface of the cushion assembly in a manner so as to allow the vibration motion of the vibration assembly to be sensed through the cushion.
