Safety Seat Back Reinforcement Structure for Rotary Plate Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety seats have complex mounting structures between the back and rotary plate, leading to high production and processing costs, and the back has low structural strength, posing safety risks due to potential deformation over time.
Innovation Solution
A back reinforcement structure comprising a reinforcement member connected to the back and rotary plate via a connector, forming an integrated stress structure to enhance strength, with a simpler design and reduced assembly costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If long round steel bars are used to run through numerous parts for mounting the back to the rotary plate, then the mounting structure achieves sufficient strength, but the production and processing costs increase due to difficult hole alignment and penetration
Solution Approach 1:
The mounting structure is divided into multiple connection points with individual connection pieces rather than using long steel bars penetrating through all parts. Each connection piece connects at a specific location, segmenting the mounting process and eliminating the need for complex hole alignment across multiple layers.
Solution Approach 2:
Connection pieces are introduced as intermediary elements between the back and rotary plate. These connection pieces simplify the mounting process by providing localized connection points that eliminate the need for long penetration bars, reducing both manufacturing complexity and cost while maintaining structural strength.
2Ease of manufacture
If the back uses a simple structure to reduce production costs, then the manufacturing cost decreases, but the structural strength becomes insufficient and the back is likely to deform after long-term use
Solution Approach 1:
The back structure uses locally reinforced areas with connection pieces positioned at critical stress points rather than uniformly thick construction throughout. This allows the back to maintain sufficient structural strength at key locations while using less material overall, reducing production costs without compromising durability.
Solution Approach 2:
The back structure combines different materials or construction methods in different areas - using stronger materials or additional reinforcement at critical connection points and stress areas, while using simpler, less expensive materials in non-critical areas. This composite approach optimizes both strength and cost-effectiveness.
