Adjustable Cantilever Seat Bracket for Variable Headrest Rod Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brackets for mounting audio/video devices on car seats have fixed distances and positions, requiring multiple specifications to accommodate varying headrest rod spacings, leading to high production, storage, and transportation costs, as well as limited adjustability for user comfort.
Innovation Solution
A cantilever bracket with pivotally connected cantilevers and a post allows for adjustable alignment with headrest rods and adjustable positioning of supported devices, eliminating the need for multiple specifications and enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between fixing seats is fixed in conventional brackets, then the structure is simple and easy to manufacture, but it cannot accommodate varying headrest rod spacings, requiring multiple specifications and increasing production, storage, and transportation costs
Solution Approach 1:
The bracket employs a telescopic structure with movable components that allow the distance between the two fixing seats to be adjusted dynamically. The telescopic mechanism enables the bracket to adapt to different headrest rod spacings by extending or retracting the central portion, transforming a static fixed-distance structure into a dynamic adjustable one.
Solution Approach 2:
The bracket is divided into multiple segments including a first fixing seat, a second fixing seat, and a telescopic mechanism with movable and stationary portions. This segmentation allows independent adjustment of each component to achieve the desired distance between fixing seats, enabling adaptability to various rod spacings while maintaining manufacturing simplicity.
2Adaptability or versatility
If multiple specifications of brackets are produced to accommodate various rod spacings, then adaptability is improved, but production, storage, and transportation costs increase
Solution Approach 1:
The bracket design achieves multi-functionality by incorporating an adjustable telescopic mechanism that allows a single bracket specification to serve multiple purposes across different rod spacing variations. This universal design eliminates the need to produce multiple specialized bracket specifications, reducing inventory complexity and associated costs.
Solution Approach 2:
The bracket utilizes parameter changes by allowing the distance between fixing seats to be varied through the telescopic mechanism. This parameter adjustment capability enables one bracket design to cover a range of rod spacing parameters, replacing the need for multiple fixed-parameter bracket specifications.
3Ease of operation
If the position of fixing seats is not adjustable in conventional brackets, then the structure remains simple, but user comfort and convenience are limited
Solution Approach 1:
The bracket transforms the static position of fixing seats into dynamic adjustable positions through the telescopic mechanism. Users can operate the adjustment mechanism to move the fixing seats to appropriate positions, enhancing user convenience and comfort while maintaining reasonable structural simplicity.

AI summary
A cantilever bracket mounted on two headrest supporting rods of a seat and includes two cantilevers and a post. The cantilever has one end provided with a fixing seat having a through channel through which the corresponding rod can pass, and the other end provided with a pivot seat. The post having one end provided with a supporting portion for supporting or hanging an object, and the other end provided with a first pivot which passes through pivot holes of the two pivot seats and pivotally connects the two cantilevers as a single unit of which the distance between the two fixing seats is adjustable. The cantilever bracket is applicable to seats of various headrest supporting rods with different spacings therebetween and eliminate the need for brackets of different specifications in accordance with the various headrest supporting rod spacings.
