Integrated Grip Vibration Handle for Operator Feedback and Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation handle structures for devices like vehicles face challenges in efficiently notifying information to the operator while suppressing grip vibration, due to limited space and increased costs associated with mounting transducers and handle weights on grips.
Innovation Solution
An operation handle structure that integrates a vibration device, including an actuator and an eccentric weight, within the grip, allowing it to function as both a vibration notifier and a handle weight, thus eliminating the need for a separate handle weight and reducing spatial and cost constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a handle weight is mounted separately on the grip to suppress vibration, then grip vibration is suppressed, but the space required and part cost increase
Solution Approach 1:
The patent combines the vibration notification device with the handle weight function by positioning the vibration device at the end portion of the grip, where it serves dual purposes: generating vibration for information notification and acting as a counterweight to suppress grip vibration. This merging eliminates the need for a separate handle weight, reducing space requirements and part costs while maintaining vibration suppression effectiveness.
Solution Approach 2:
The vibration device is designed to perform multiple functions simultaneously: it generates vibration for notifying the operator of device states and operates as a handle weight to suppress unwanted grip vibration. This multi-functionality approach allows a single component to address both information notification and vibration control needs, reducing the overall number of parts and space required.
2Reliability
If both transducer and handle weight are mounted on the grip, then vibration notification and suppression are achieved, but part cost increases
Solution Approach 1:
The patent merges the transducer (vibration device) with the handle weight into a single integrated solution. The vibration device positioned at the grip's end portion serves both as the notification transducer and as the handle weight, eliminating the need for separate components and reducing overall part cost while maintaining both notification reliability and vibration suppression.
Solution Approach 2:
The vibration device is designed with multi-functionality to simultaneously provide information notification through vibration and serve as a handle weight for vibration suppression. This approach reduces part cost by eliminating redundant components while ensuring both notification and vibration control functions are effectively performed.
3Reliability
If both transducer and handle weight are mounted on the grip, then vibration notification and suppression are achieved, but the number of parts increases
Solution Approach 1:
The patent combines the transducer and handle weight into a single integrated system by positioning the vibration device at the end portion of the grip. This merging reduces the number of parts from two separate components (transducer plus handle weight) to one unified component, simplifying the device while maintaining both notification and vibration suppression reliability.
Solution Approach 2:
The vibration device is designed to perform multiple functions simultaneously, eliminating the need for separate transducer and handle weight components. This multi-functionality approach reduces device complexity and the number of parts while ensuring both information notification and vibration suppression are reliably achieved.
