Vehicle Headrest Mounting System for Universal Device Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle entertainment systems lack a universal mounting solution that can accommodate different sized mobile computing devices, such as tablet computers and smartphones, without requiring modifications to the devices or the vehicle's infrastructure.
Innovation Solution
A vehicle entertainment cradle system featuring a primary adapter and secondary adapter, both with form-fitting lips and recesses, allowing for secure and flush mounting of various sized devices within the cradle, which is electrically connected to the vehicle's power and audio/video systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal mounting solution is designed to accommodate different sized devices, then adaptability is improved, but device complexity increases due to multiple adapter configurations
Solution Approach 1:
The mounting system is divided into a cradle component and multiple adapter components. Each adapter is designed as a separate segment that can be independently attached to the cradle, allowing the system to accommodate different device sizes without requiring a completely different mounting structure for each device type.
Solution Approach 2:
The cradle is designed with a universal interface that can accept different adapter types. The adapters share common attachment mechanisms with the cradle, enabling a single cradle unit to serve multiple functions by simply changing the adapter, thereby reducing the need for multiple dedicated mounting structures.
2Reliability
If form-fitting lips and recesses are used to secure devices, then reliability of mounting is improved, but manufacturing precision requirements increase
Solution Approach 1:
The form-fitting engagement between lips and recesses is implemented only at the specific interface points where devices attach to adapters and adapters attach to the cradle. This localized precision requirement is concentrated at discrete attachment points rather than requiring precision across the entire structure, making manufacturing more feasible.
Solution Approach 2:
The mounting system uses a nested structure where adapters are inserted into the cradle, and devices are inserted into adapters. This nesting arrangement allows the form-fitting lips and recesses to engage at multiple hierarchical levels, providing redundant securement points that enhance reliability while distributing manufacturing tolerances across multiple interfaces.
3Adaptability or versatility
If multiple adapters are used to accommodate different device sizes, then adaptability is improved, but ease of operation decreases due to adapter switching
Solution Approach 1:
The adapter attachment mechanism incorporates dynamic elements such as spring-loaded lips or snap-fit features that allow adapters to be quickly attached and detached without requiring complex tools or procedures. The spring mechanism automatically engages when an adapter is inserted and can be easily released, making the switching process simple and rapid.

AI summary
A mounting system includes a cradle disposed in a headrest in a vehicle, and a primary adapter. The cradle is shaped and dimensioned to receive the primary adapter. The primary adapter includes first to fourth lips forming a recess in the primary adapter. The recess is shaped and dimensioned to receive a first computing device or a secondary adapter. The first computing device, or a bezel of the secondary adapter, is substantially flush with an outer surface of the headrest upon mounting the first computing device or the secondary adapter to the primary adapter.
