Telescopic Mounting Rod for Vehicle Seat Headrest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile device brackets for vehicle seats are structurally complex and difficult to install, leading to user fatigue as passengers often hold devices to watch during travel due to lack of reliable placement.
Innovation Solution
An extension tube-type vehicle-mounted back support with an elastically telescopic mounting rod, featuring a connector, connection tubes, clamping parts with telescopic springs, and a rotating rod with ball joint assembly for simple and stable installation, allowing easy attachment and detachment from the seat headrest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional mobile phone bracket is mounted on the back of the seat, then passengers can place mobile devices to reduce fatigue, but the structural design becomes complicated and installation becomes troublesome
Solution Approach 1:
The mounting rod is divided into multiple telescopic sections (first connection tube, second connection tube, third connection tube) that can slide relative to each other, allowing the structure to be segmented for easy installation while maintaining overall simplicity
Solution Approach 2:
The telescopic sections are nested within each other, with the first connection tube containing the second, and the second containing the third. This nested structure allows compact storage and simple installation without complex mechanisms
2Device complexity
If the mounting rod is designed as an elastically telescopic structure, then installation becomes simple and structure becomes compact, but the mechanism requires springs and moving parts
Solution Approach 1:
The telescopic mechanism merges the spring element, connection tubes, and clamping function into a single integrated assembly. The spring is housed within the connection tubes, and the clamping parts are attached to the telescopic sections, combining multiple functions into one compact structure
Solution Approach 2:
The telescopic spring automatically provides the clamping force needed to secure the mounting rod to the headrest. When the mounting rod is installed, the spring self-compresses to generate clamping pressure on the headrest surface, eliminating the need for separate fastening mechanisms
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 solution provides a simple, compact, and stable mounting system that reduces user fatigue by allowing easy placement and secure holding of mobile devices, enhancing the viewing experience during travel.
Implementation Method 1
At least one of the connection tubes is internally provided with a telescopic spring. A corresponding one of the clamping parts is biased by the telescopic spring to move left and right relative to the connection tube having the telescopic spring.

AI summary
Disclosed is an extension tube-type vehicle-mounted back support comprising a mounting rod and a mounting part mounted on the mounting rod and used for fixing a mobile terminal. The mounting rod comprises a connector and two connection tubes respectively connected to the left and right ends of the connector, wherein outer ends of the two connection tubes are both connected to a clamping part, an extension spring is provided inside at least one of the connection tubes, and the corresponding clamping part is arranged in a manner of shifting to the left and right relative to the connection tube with the action of the extension spring. The overall structure of the mounting rod is simple and compact and has good stability. By designing the mounting rod as an elastically extending structure, the mounting rod can be directly installed on a vehicle seat headrest metal rod.
