2D Input Apparatus with Directional Determination for Unintended Operation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input apparatuses for vehicles often result in unintended operations when an operator accidentally touches the operation member, leading to cumbersome additional operations required to prevent such unintended functions, such as pressing a separate switch for determination.
Innovation Solution
An input apparatus with an operation member supported movably on a two-dimensional plane, including a section detection mechanism and a determination operation detection system that performs processes based on the detected section and determination operation, where the determination operation is done in a direction parallel to the plane, simplifying the structure and operation by eliminating the need for a separate switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a determination operation is performed through a separate switch, then unintended operations are prevented, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent merges the determination operation function into the operation member itself by enabling determination through movement in a specific direction (determination direction) within the two-dimensional plane. This eliminates the need for a separate switch or button, thereby preventing unintended operations while maintaining simple structure and ease of operation.
Solution Approach 2:
The operation member is designed to perform multiple functions: it can be moved in various directions to select different sections, and movement in the determination direction serves as both selection and determination. This multi-functionality prevents unintended operations without adding separate determination mechanisms.
2Reliability
If a separate switch is provided for determination operation, then unintended operations are prevented, but the ease of operation deteriorates
Solution Approach 1:
The determination operation is merged into the movement operation itself. By moving the operation member in the determination direction within the two-dimensional plane, the user simultaneously performs selection and determination, eliminating the need for separate determination actions and maintaining operational simplicity.
Solution Approach 2:
The operation member serves universal purposes: movement in any direction selects sections, and movement in the determination direction also determines the selection. This eliminates the need for separate determination operations, keeping the interface simple while preventing unintended operations.
3Reliability
If an operation other than movement along the two-dimensional plane is required for determination, then unintended operations are prevented, but the ease of operation and structure simplicity deteriorate
Solution Approach 1:
The determination operation is merged into the two-dimensional movement itself. By defining movement in a specific direction (determination direction) within the existing two-dimensional plane as the determination action, the system prevents unintended operations without requiring additional operational dimensions or separate controls.
Solution Approach 2:
The operation member maintains its two-dimensional movement capability while adding determination function through directional movement. This universal design allows the same movement mechanism to serve both selection and determination purposes, keeping the structure simple while preventing unintended operations.

AI summary
An input apparatus includes an operation member supported movably in accordance with a plurality of sections set on a two-dimensional plane, a section detection section configured to detect a section in which the operation member is located, a determination operation detection section configured to detect a determination operation performed using the operation member, and an execution section configured to perform a process corresponding to the section in which the operation member is located on the basis of the section detected by the section detection section and the determination operation detected by the determination operation detection section. The determination operation is movement of the operation member in a determination direction (y1 direction), which is a direction parallel to the two-dimensional plane.
