Vehicle Input Control With Tactile Feedback and Minimal Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operation input devices require significant movement of the operating part to input operation information, which can be inconvenient and may lead to uncertainty in operation feedback.
Innovation Solution
An operation input device with a support part, an operating member, an operation sensing part, a tactile feedback generating part, and a control part, where the operating member extends in a direction intersecting the vehicle's travel direction and is restricted from rotating, allowing for minimal movement input with tactile feedback confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operating part is manually moved to input operation information, then operation information can be input, but the position of the operating part must be displaced significantly
Solution Approach 1:
The patent replaces the traditional mechanical displacement-based operation input with a tactile feedback-based sensing system. The operation sensing part detects operations through tactile feedback rather than requiring significant mechanical movement of the operating member, thereby substituting a mechanical system with a sensing system.
Solution Approach 2:
The patent introduces tactile feedback as a mediator between the operating member and the operator. The tactile feedback generating part provides sensory feedback to the operator, enabling operation input with minimal displacement by relying on tactile sensation rather than visual or mechanical feedback.
2Length of moving object
If the operating member is restricted from rotating, then minimal movement input is enabled, but the operating member cannot provide traditional lever-like swing operation
Solution Approach 1:
The patent replaces the mechanical swing operation mechanism with an operation sensing part that detects tactile feedback. This substitution allows the operating member to remain restricted while still enabling operation input through tactile sensation rather than mechanical movement.
Solution Approach 2:
The patent introduces tactile feedback as an intermediary between the restricted operating member and the operation input function. The tactile feedback generating part mediates the interaction, allowing the operator to input commands through tactile sensation even when the operating member cannot swing or rotate.

AI summary
An operation input device to be mounted on a vehicle includes a support part to be attached to the vehicle, an operating member supported by the support part and configured to be operated by a person, an operation sensing part configured to sense an operation on the operating member, a tactile feedback generating part provided inside the operating member and configured to give tactile feedback to the person, and a control part configured to control the tactile feedback generating part to produce the tactile feedback when the operation is sensed in the operation sensing part, the operating member is provided so as to extend from the support part in a first direction intersecting the traveling direction of the vehicle, and the operating member is restricted so as not to rotate in a swing operation in which a direction intersecting the first direction serves as the axis of rotation.
