Vehicle Power Window Automatic Mode via Extended Switch Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power window apparatuses for vehicles do not allow non-driver seat windows to be opened or closed in automatic operation mode when the operation switch on the non-driver seat lacks an automatic operation function, and the configuration of switches with automatic operation functions becomes complicated due to the need for multiple switchable positions.
Innovation Solution
A power window apparatus with a driver seat unit and a non-driver seat switch that includes a manual switch for manual operation, a switching circuit, and a detecting unit (voltage and current detection circuits) to transition the operation to automatic mode after extended operation, allowing automatic opening or closing of non-driver seat windows even when the switch is released.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a manual switch is used for non-driver seat window operation, then the switch configuration is simple, but automatic operation mode cannot be achieved
Solution Approach 1:
The patent applies the dynamics principle by enabling the manual switch to dynamically transition between manual operation mode and automatic operation mode based on the duration of switch activation. When the switch is pressed for a predetermined time or more, the system automatically transitions to automatic operation mode, allowing the window to open or close completely without continuous switch activation. This dynamic behavior resolves the contradiction by maintaining a simple manual switch configuration while achieving automatic operation functionality.
2Extent of automation
If a switch with automatic operation function is provided, then automatic window operation is enabled, but the switch requires multiple operation positions which complicates the configuration
Solution Approach 1:
The patent applies the universality principle by designing a manual switch that serves multiple functions: it can operate in manual mode for short presses and in automatic mode for long presses (predetermined time or more). This multi-functional switch eliminates the need for separate switches or complex multi-position switches, thereby simplifying the switch configuration while maintaining automatic operation capability and ease of use.
3Device complexity
If manual operation mode is used, then the switch configuration remains simple, but continuous manual activation is required for window operation
Solution Approach 1:
The patent applies the preliminary action principle by requiring the user to press the switch for a predetermined time duration to preliminarily activate automatic operation mode. Once this preliminary action is completed, the window operation proceeds automatically without requiring continuous manual activation. This resolves the contradiction by maintaining simple switch configuration while significantly reducing the time and effort required for window operation.

AI summary
A vehicle power window apparatus includes: a driver seat unit and a first non-driver seat switch which is a manual switch provided on a non-driver seat to open and close a non-driver seat window. The driver seat unit includes a switching circuit operated based on a predetermined operation of the first non-driver seat switch. When an extended operation of the first non-driver seat switch set by operating the first non-driver seat switch for a certain time period or more is detected, the control unit drives the switching circuit. After the extended operation of the first non-driver seat switch is released, the control unit fully opens or closes the non-driver seat window in an automatic operation mode by energizing the non-driver seat motor via the switching circuit and the first non-driver seat switch by the power supply.
