Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holder systems for electronic devices in vehicles are bulky, visually distracting, and require specific adaptations for different devices, making them inconvenient and inefficient for modern telecommunications devices with varying dimensions and charging methods.
Innovation Solution
A holder system featuring L-shaped lugs and bayonet lock mechanisms with magnetic attraction for secure attachment, a compact design with magnetic guidance, and adjustable arms for universal compatibility, allowing for easy alignment and secure positioning of devices without visible locking elements, and enabling inductive charging without a galvanic connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a built-in holder for electronic devices is installed in the vehicle, then the device can be securely held and charged, but the holder becomes visually distracting and bulky in the vehicle interior
Solution Approach 1:
The holder system is divided into two separate components: a receiving part built into the vehicle and a holder that can be detached. This segmentation allows the vehicle interior to remain clean and uncluttered when the holder is not in use, while still providing secure holding capability when needed.
Solution Approach 2:
The holder can be inserted into the receiving part, creating a nested configuration where the holder fits within the vehicle's built-in structure. This nesting approach minimizes the visible footprint in the vehicle interior while maintaining full functionality.
2Reliability
If the holder is mechanically and electrically adapted to a specific device type, then reliable connection is achieved, but the system lacks adaptability to different telecommunications devices
Solution Approach 1:
The holder and receiving part are designed with universal interfaces that can accommodate different types of telecommunications devices. The electrical connection system uses standardized contacts that can work with various device types, eliminating the need for device-specific adaptations while maintaining reliable connections.
3Reliability
If contact connections are used for power supply, then reliable electrical connection is achieved, but the system requires precise alignment and increases device complexity
Solution Approach 1:
The patent replaces traditional mechanical contact connections with inductive coupling for power transmission. This substitution eliminates the need for precise mechanical alignment of electrical contacts, reduces wear and tear, and simplifies the overall connection mechanism while maintaining reliable power supply.
4Area of stationary object
If the holder is made compact and discreet, then aesthetic appearance is improved, but the holding strength and security are reduced
Solution Approach 1:
The holder incorporates a spring mechanism that预先 stores mechanical energy. When the holder is inserted into the receiving part, the spring automatically engages and provides strong holding force, ensuring secure attachment even though the holder itself remains compact and discreet in appearance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a compact, visually appealing, and user-friendly solution for attaching and charging various electronic devices, ensuring secure attachment, efficient charging, and adaptability to different devices, while preventing accidental polarity reversal and short circuits.
Implementation Method 1
magnets or ferromagnetic pieces are inserted into the fastening plate on the one hand and into the rear wall on the other hand
Implementation Method 2
telecommunications devices have been known and marketed for some time now that can be inductively charged via an induction coil rather than a cable connection
