Modular Vehicle Seat Backrest for Fast Assembly and Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat backrests lack a modular design that allows for easy assembly and adaptation of functionalities, requiring complex and time-consuming assembly processes and limiting the ability to replace components without disassembling the entire structure.
Innovation Solution
A vehicle seat backrest comprising a backrest armature, a central upholstery module, and two side upholstery modules, each independently fixable to the armature, enabling quick assembly and adaptation of functionalities through modular components such as elastic means, air pumps, inflatable pouches, and comfort features like loudspeakers, while allowing for the replacement of central modules without disassembling side modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional non-modular backrest design is used, then the structural integrity is maintained, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The backrest is divided into three independent upholstery modules (two side modules and one central module) that can be assembled separately onto the backrest armature. Each module has its own support structure and can be fixed independently, transforming a single complex assembly into multiple simple modular units that can be produced and assembled in parallel, significantly improving productivity while reducing assembly process complexity
2Adaptability or versatility
If the backrest is designed as a single integrated unit, then the structural stability is ensured, but the ability to adapt functionalities is limited
Solution Approach 1:
The backrest is segmented into three independent upholstery modules, each with its own support structure that can be fixed to the backrest armature independently. This modular architecture allows different functional configurations (e.g., heating, ventilation, massage) to be implemented in specific modules without affecting the overall structural stability, as each module maintains its own structural integrity while contributing to the whole
Solution Approach 2:
The standardized support structures and fixation mechanisms across all three modules enable universal applicability of various functional components. The same support design can accommodate different functionalities (heating elements, ventilation channels, massage mechanisms) in any module, allowing the backrest to be adapted for multiple functions while maintaining structural consistency
3Ease of repair
If upholstery modules are interconnected, then the overall support is strengthened, but the ease of replacement is reduced
Solution Approach 1:
Each upholstery module has its own independent support structure that attaches directly to the backrest armature, creating clear separation between modules. This segmentation allows any single module to be removed and replaced without affecting the other modules or requiring disassembly of interconnected components, significantly improving ease of repair while maintaining overall support strength through the distributed modular architecture

AI summary
A backrest of a vehicle seat comprises a backrest armature, at least one central upholstery module and two side upholstery modules each arranged on a respective side of the central upholstery module. Each of the at least three upholstery modules is fixed to the backrest armature independently of the other two upholstery modules.
