Seatback Holder with Retractable Arm and Rotating Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device holders for vehicles, such as aircrafts and trains, fail to provide stable and comfortable device support for various formats like smartphones and tablets while minimizing space usage and avoiding uncomfortable projections, and they do not adequately address the need for adaptability and protection during vibrations and jerks.
Innovation Solution
A plate-like holder with an extendable arm and rotating holding elements, featuring locking teeth, that can adapt to different device formats by adjusting its position to ensure maximum stability and protection, and remains virtually invisible when not in use by minimizing projections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If projecting hooks and resting bases are used to hold the device, then the device can be securely held, but the holder becomes uncomfortable and undesirable when the device is not in use
Solution Approach 1:
The holder employs dynamic elements including a retractable arm that can extend to support the device and retract when not in use, and rotating holding elements that can pivot between a vertical adhered position and a rotated operational position. This allows the holder to adapt its configuration based on whether the device is being used, eliminating unwanted projections when the device is removed while maintaining secure holding capability when needed.
2Adaptability or versatility
If the holder structure is made more complex to accommodate various device formats, then adaptability improves, but the holder occupies more space and becomes more visible when not in use
Solution Approach 1:
The holder integrates the retractable arm within the plate-like holder body, allowing the arm to be stored inside or alongside the holder structure when not in use. This nesting approach enables the holder to maintain a compact profile while providing extended functionality when needed, accommodating various device formats without permanently occupying additional space.
Solution Approach 2:
The rotating holding elements can pivot between a vertical adhered position (minimal profile) and a rotated operational position (device-supporting configuration). This dynamic transformation allows the holder to adapt its structure for different device formats while maintaining a compact, minimal appearance when not in use.
3Weight of moving object
If the holder structure is made lighter to reduce weight, then weight control is improved, but the holder may have reduced stability during vehicle movements
Solution Approach 1:
The holder is constructed from composite materials that provide high strength-to-weight ratio, enabling the structure to remain lightweight while maintaining sufficient stability to resist vibrations and jerks during vehicle movements. The adhesive plate provides a stable base, while the strategically positioned holding elements deliver targeted support with minimal mass.
4Area of stationary object
If the holder is designed to be minimal and invisible when not in use, then space is minimized, but it may be difficult to ensure maximum stability when in use
Solution Approach 1:
The holder transforms from a minimal plate-like structure to a fully functional support system through the rotation of holding elements and extension of the arm. When in use, the holding elements pivot to create a stable cradle with multiple contact points, while the extendable arm provides additional support. This dynamic transformation enables the holder to achieve maximum stability during use while maintaining a minimal profile when not in use.
