Adjustable Headrest Mount for Secure Tablet and Phone Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retaining systems for motor vehicles are inadequate for securely fastening large pieces of equipment with displays, as they lack flexibility and adaptability to accommodate devices of varying sizes and orientations, particularly for rear-seat passengers.
Innovation Solution
A retaining device with a holding apparatus featuring displaceable retaining elements that adjust to the length and width of the equipment, allowing for secure fastening and easy conversion between different devices, including the option to pivot for optimal orientation and accommodate various thicknesses, and is designed to be mounted on a headrest for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a suction pad is used to fasten equipment on the side window, then the equipment can be easily attached, but it is extremely unsuitable for large pieces of equipment and does not provide secure fastening
Solution Approach 1:
The retaining device employs displaceable retaining elements that can be adjusted dynamically to match the dimensions of different equipment pieces. The holding apparatus can adapt its holding space dimensions through displacement of retaining elements, providing secure fastening for various sizes of equipment while maintaining ease of operation.
2Reliability
If a retaining system is designed for mobile phones with fixed dimensions, then it can securely hold small devices, but it lacks adaptability for larger equipment like tablet PCs
Solution Approach 1:
The retaining device features displaceable retaining elements that enable dynamic adjustment of the holding space dimensions. This allows the same device to securely hold both small mobile phones and larger tablet PCs by adapting the holding space to match the specific dimensions of the equipment being retained.
Solution Approach 2:
The retaining device is designed with universal applicability through its adjustable holding apparatus. By incorporating displaceable retaining elements, a single device can serve multiple functions for different types and sizes of equipment, eliminating the need for separate retaining systems for phones, tablets, and other display-equipped devices.
3Adaptability or versatility
If telescopic columns with fixed adjustment ranges are used, then portable computers can be retained, but the range of adjustment is limited and cannot accommodate equipment longer than the maximum extent
Solution Approach 1:
The retaining device incorporates displaceable retaining elements that can be adjusted to extend the holding space beyond fixed telescopic column limitations. This dynamic adjustment capability allows equipment of various lengths to be securely retained while maintaining adaptability to different sizes.
4Device complexity
If the holding space is fixed in size, then the device structure is simple, but it cannot accommodate equipment of varying sizes and orientations
Solution Approach 1:
The retaining device introduces displaceable retaining elements that provide adjustable holding space dimensions. While this increases structural complexity compared to a fixed design, it enables the device to accommodate equipment of varying sizes and orientations, achieving versatility through controlled complexity.

AI summary
A retaining device for fastening a piece of equipment with a display inside a motor vehicle has a holding apparatus with a bearing surface and a holding space for holding the piece of equipment. The holding space extends in a first direction (R1) up to a first maximum extent, and extends in a second direction (R2) perpendicular to the first direction (R1). For pieces of equipment that are smaller, the amount by which the holding space extends in the first direction (R1) can be adjusted to the length of the piece of equipment and the amount by which the holding space extends in the second direction (R2) can be adjusted to its width. For pieces of equipment that are longer, the holding space can be adjusted to the width and the amount by which the holding space extends in the second direction (R2) can be adjusted to its length.
