Haptic Pressure Receiver Structure for Low-Power Vibration Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional haptic information presentation systems require high power consumption to transmit vibrations, and the actuator is subjected to high loads when transmitting physical stimuli through input devices like sticks or buttons, leading to increased power consumption and potential inefficiencies.
Innovation Solution
The stimulus transmission device separates the actuator from the housing, using a supporting portion that does not move with the actuator, allowing the actuator and pressure receiving portion to move independently and efficiently transmit vibrations without moving the housing, thereby reducing power consumption and enhancing stimulus transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the actuator is integrated with the housing to transmit vibration stimulus, then the vibration stimulus is transmitted to the user, but high power consumption is required to vibrate the entire housing
Solution Approach 1:
The patent divides the housing into a fixed portion and a movable portion, allowing only the movable portion to vibrate while the fixed portion remains stationary. This segmentation reduces the mass that needs to be accelerated, thereby reducing power consumption while maintaining effective vibration transmission to the user.
Solution Approach 2:
The patent extracts the vibration transmission function from the entire housing and concentrates it in a specific movable portion. By isolating the vibration-generating components and their immediate support structure from the main housing body, the system achieves efficient stimulus transmission with minimal power consumption.
2Device complexity
If the actuator is integrated with the housing, then the structure is simplified, but high load is applied to the actuator and power consumption increases
Solution Approach 1:
The patent segments the housing structure into fixed and movable portions, allowing the actuator to drive only the necessary movable components rather than the entire housing. This reduces the mechanical load on the actuator while maintaining structural integrity through the fixed portion.
Solution Approach 2:
The patent applies different structural properties to different portions of the housing: the fixed portion provides stable support with high rigidity, while the movable portion is designed for vibration with appropriate flexibility. This local differentiation optimizes both structural strength and vibration transmission efficiency.

AI summary
A stimulus transmission device suppresses power consumption, and effectively transmits a physical stimulus to a user. The stimulus transmission device has a pressure receiving portion which receives pressure from part of a human body, an actuator which drives the pressure receiving portion, and a supporting portion which supports the actuator. The actuator does not move in conjunction with the supporting portion.
