Selective Vehicle Window Control via Remote Demand Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle power window systems lack the ability to control each window independently via a portable remote control, forcing users to actuate all windows simultaneously, which is inconvenient for tasks like providing fresh air or closing a specific window.
Innovation Solution
A system with a portable remote control and wireless transceivers that allow users to selectively control specific windows by generating and transmitting unique demand signals to the vehicle's electronic control unit, enabling independent operation of each window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single signal is sent to the electronic control unit to actuate all power windows simultaneously, then the system structure remains simple, but the ability to control each window independently is lost
Solution Approach 1:
The remote control system is segmented into multiple activation switches, with each switch corresponding to a specific window. When a user actuates a particular switch, only the corresponding window receives the control signal. This segmentation allows independent control of each window while maintaining a relatively simple overall system structure.
Solution Approach 2:
Each activation switch in the remote control is assigned a specific function corresponding to a particular window. The system transmits localized control signals that affect only the targeted window rather than all windows uniformly. This local quality approach enables precise control of individual windows while preserving system simplicity.
2Ease of operation
If multiple activation switches are added to the portable remote control for selective window control, then independent window control is enabled, but the complexity of the remote control increases
Solution Approach 1:
Multiple activation switches are integrated into a single portable remote control unit, allowing one device to perform multiple functions. Each switch provides a specific control function for different windows, making the remote control universal and multi-functional while keeping the overall device compact and manageable.
Solution Approach 2:
The system merges multiple control functions into a single portable remote control device. All activation switches for different windows are combined in one handheld unit, allowing users to control multiple windows from a single location without needing separate controls for each window.
3Ease of operation
If all power windows are actuated simultaneously by a single signal, then the system response is fast and simple, but user convenience for selective control is reduced
Solution Approach 1:
The remote control is prepared in advance with multiple activation switches, each pre-assigned to control a specific window. When the user needs to control a particular window, they simply actuate the corresponding pre-configured switch without needing to navigate through menus or perform additional steps, enabling quick and convenient selective control.

AI summary
A system and method for selectively controlling a specific window of a power window system of a vehicle. The system includes a portable remote control including activation switches, each corresponding to a specific power window of a vehicle, a first wireless transceiver mounted onto the vehicle, and a second wireless transceiver disposed in the portable remote control. Actuation of an activation switch causes the second wireless transceiver to communicate a demand signal to the first wireless transceiver that identifies the specific power window of the vehicle corresponding to the actuated activation switch. The first wireless transceiver receives the demand signal and communicates instruction to an electronic control unit of the vehicle to actuate the specific window identified by the demand signal. The electronic control unit then actuates the specific power window of the vehicle that corresponds to the activation switch initially actuated.
