Vehicle Backrest Suspension Core for Controlled Rotation and Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle backrest suspension systems are cumbersome to transport and assemble, and they lack effective control over rotational movements, compromising user comfort and structural integrity.
Innovation Solution
A suspension system comprising a structural core with a main support and ancillary support, connected by a wire, allowing for controlled rotational movements and easy assembly, using a modular design that facilitates transport and attachment to the backrest frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional backrest suspension system is used, then the structural integrity is maintained, but the system is cumbersome to transport and assemble
Solution Approach 1:
The backrest suspension system is divided into separate modular components: a structural core, a main support assembly, and an ancillary support assembly. These modules can be manufactured independently and transported separately, then assembled together at the destination. The main support assembly includes a main plate with engagement members, the ancillary support assembly includes an ancillary plate with engagement members, and the structural core provides the suspension function. This segmentation enables easier transport and assembly while maintaining structural integrity.
2Ease of operation
If the backrest suspension system allows movement for user comfort, then user comfort is improved, but rotational movements are not effectively controlled
Solution Approach 1:
The suspension system incorporates dynamic characteristics through the structural core made of elastic material (such as a wire with specific cross-section between 10-100 mm²) that allows controlled deflection and movement in the elevation direction to accommodate user comfort. Simultaneously, the engagement members (elastic engagement members on the main support and ancillary support) provide controlled rotational stability by mechanically interlocking with the structural core, preventing unwanted rotational movements about the transverse axis while permitting necessary suspension movement.
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 system enhances user comfort by allowing controlled rotational movements and simplifies assembly and transport, while maintaining structural integrity through a robust connection to the backrest frame.
Implementation Method 1
the structural core allows a robust holding of the main support and of the ancillary support, in order to connect them to the frame (of the backrest), while allowing a deflection of movement to comfortably accommodate the back of a user
