Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices for motor vehicles often compromise actuation convenience while inadequately preventing undesirable component control, leading to impaired usability and incorrect triggering.
Innovation Solution
A remote control device with a transmitting device and position detection system that allows for two operating modes based on the device's actual position, enabling convenient and reliable control of motor vehicle components by varying the actuation method and signal emission criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remote control device emits signals based on simple switch actuation without position detection, then the actuation convenience is high, but incorrect triggering occurs when the device is in unintended positions (e.g., in a pocket)
Solution Approach 1:
The patent changes the operational parameters of the remote control device based on the detected actual position. When the device detects it is in a horizontal position (likely in a pocket), it requires a different actuation pattern (e.g., longer press duration or specific sequence) compared to when held in a vertical position (normal use). This parameter adaptation prevents accidental triggering while maintaining ease of use in the correct orientation.
Solution Approach 2:
The remote control device dynamically adjusts its signal emission behavior based on real-time position detection. The system transitions between different operational states (modes) depending on the detected orientation, making the actuation requirements dynamic rather than static. This allows the device to be more restrictive when horizontally positioned and more responsive when vertically positioned, resolving the contradiction between reliability and ease of operation.
2Reliability
If the remote control device requires complex actuation procedures to prevent incorrect triggering, then the reliability improves, but the actuation convenience deteriorates
Solution Approach 1:
The system dynamically adapts the actuation complexity based on the detected position. In horizontal positions where incorrect triggering is likely, the system implements more complex actuation requirements. In vertical positions where correct usage is assumed, the system simplifies the actuation process. This dynamic adjustment ensures high reliability only when needed, maintaining actuation convenience during normal use.
3Reliability
If the remote control device operates in a single mode regardless of position, then the device complexity is low, but the ability to prevent incorrect control in varying orientations is insufficient
Solution Approach 1:
The patent implements a dynamic operating mode system where the remote control device automatically switches between at least two different operating modes based on the detected actual position. The position detection device continuously monitors the device orientation and triggers mode transitions accordingly. This dynamic multi-mode operation enables the system to prevent incorrect triggering in varying orientations while keeping the overall device architecture relatively simple, as the mode switching is automatically driven by position detection rather than requiring complex user configuration.

AI summary
A remote control device for a motor vehicle has a transmitting unit to transmit at least one signal, for remote control of at least one component of the motor vehicle. A switch effects transmission of the signal by operating the switch. A position detection device is provided, by which an actual position of the remote control device relative to a specifiable reference position can be detected. The signal is transmitted on the basis of the detected actual position. A method operates such a remote control device.
