Vehicle Seat Cover Assembly with Clip Alignment Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat manufacturing processes rely heavily on manual labor, leading to low productivity, inefficient work, and musculoskeletal issues due to the use of heavy hook ring machines.
Innovation Solution
A vehicle seat assembly apparatus comprising a base portion with a cushion operating portion and a cover operating portion, which automates the process of coupling a seat cover to a seat cushion by aligning clips on a suspender using a combination of supporting stands, lifting portions, and holders, allowing for efficient transfer and fixation of the seat cover onto the cushion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual labor is used for seat cover assembly, then workers can perform the task with simple equipment, but productivity is low and workers develop musculoskeletal diseases
Solution Approach 1:
The patent replaces manual mechanical operations with an automated assembly apparatus that uses mechanical systems to perform seat cover assembly tasks. The apparatus includes automated feeding mechanisms, positioning systems, and fastening devices that eliminate the need for workers to manually handle heavy hook ring machines, thereby resolving the contradiction between productivity improvement and equipment complexity.
Solution Approach 2:
The assembly apparatus is designed to perform assembly operations autonomously without continuous human intervention. The system automatically feeds components, positions the seat cover, applies fasteners, and completes the assembly process, allowing the equipment to serve itself in performing the assembly task while maintaining high productivity.
2Reliability
If heavy hook ring machines are used for fastening, then the seat cover can be securely attached, but workers develop musculoskeletal diseases due to continuous heavy operation
Solution Approach 1:
The patent replaces the heavy hook ring machine with an automated fastening system that uses controlled mechanical forces applied by the apparatus. The system incorporates positioning mechanisms and automated fastening devices that apply precise forces to secure the seat cover reliably without requiring workers to operate heavy equipment, thereby eliminating the harmful health effects while maintaining attachment reliability.
Solution Approach 2:
The assembly apparatus acts as an intermediary between the seat cover and the fastening mechanism. It incorporates positioning structures and guiding elements that ensure proper alignment and distribution of forces during fastening, mediating the interaction to achieve reliable attachment while protecting workers from direct exposure to heavy mechanical operations.
3Manufacturing precision
If multiple work processes are used for seat assembly, then the seat cover can be properly installed, but the number of processes reduces workability and productivity
Solution Approach 1:
The patent combines multiple separate work processes into a single integrated assembly apparatus. The system performs feeding, positioning, fastening, and finishing operations in one continuous automated process, eliminating the need for multiple separate manual operations. This merging of processes maintains manufacturing precision while significantly improving productivity by reducing process transitions and handling steps.
Solution Approach 2:
The assembly apparatus is designed to perform operations in a continuous automated sequence without interruption. Components are fed continuously, positioned automatically, and fastened in a seamless flow, eliminating the stop-start nature of multiple manual processes. This continuity maintains precision through consistent automated execution while maximizing productivity by eliminating idle time between operations.

AI summary
A vehicle seat assembly apparatus includes: a base part; a cushion working part which is joined to one side of the base part and with which a seat cushion having a plurality of first through-holes formed therein can be placed and a seat cover can be joined to the seat cushion; and a cover working part which is joined to the other side of the base part and with which the seat cover can be placed and the seat cover can be moved to an upper part of the seat cushion. The cover working part makes it possible to align the angles of clips to be joined to suspenders of the seat cover.
