Spring Cover Mounting for Seat Reclining Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing seat reclining apparatus has room for improvement in the manner of fixing the spring cover to the base plate, which affects its secure and easy mounting.
Innovation Solution
The apparatus includes a spring cover that is securely mounted to the outer surface of the base plate or ratchet plate, with a protrusion on the spring cover contacting the inner surface of the seat frame, enhancing the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spring cover is mounted to the base plate using conventional methods, then the mounting process is simple, but the mounting security and reliability are insufficient
Solution Approach 1:
The spring cover's protrusion automatically engages with the seat frame's groove during assembly, creating a self-aligning and self-securing mounting mechanism that eliminates the need for additional fasteners or complex attachment procedures
Solution Approach 2:
The protrusion of the spring cover fits into the groove of the seat frame, creating a nested connection where one component is inserted into another, providing secure mounting while maintaining structural simplicity
2Reliability
If the spring cover is securely fixed to ensure reliability, then the mounting security improves, but the ease of manufacture decreases
Solution Approach 1:
The spring cover is designed as a separate component with an integrated protrusion, allowing it to be manufactured independently and then assembled to the base plate, simplifying the manufacturing process while ensuring secure mounting
Solution Approach 2:
The protrusion acts as an intermediary element between the spring cover and the seat frame, providing a simple yet effective connection mechanism that is easy to manufacture but ensures reliable mounting
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 spring cover can be easily and securely mounted, providing a stable and reliable mechanism for adjusting the seatback angle, ensuring the seat reclining apparatus functions effectively.
Implementation Method 1
a lock spring (spiral spring) which biases and rotates the rotational center shaft
