Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckle devices for motion simulation chairs suffer from insufficient durability due to spring fatigue, complex assembly processes, and a complicated structure, particularly at the junctions between tension springs and fasteners, leading to brittleness and increased assembly difficulty.
Innovation Solution
A buckle device design featuring a main unit with a housing, disk unit, press unit, and elastic unit, utilizing thrust springs that eliminate the need for annular fasteners, allowing for smoother operation and extended lifespan by integrating a spring disk support region and press support region to push the vertical disk and press body, respectively, while maintaining the buckle's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tension springs with annular fasteners are used to provide tensile force between objects, then the buckles can be fastened and provide securing force, but the junction between the spring and fastener becomes brittle over time due to spring fatigue, reducing durability
Solution Approach 1:
The patent removes the annular fastener component from the spring assembly, extracting the source of the brittle junction. The spring directly engages with the connecting regions without requiring separate fasteners, eliminating the fatigue-prone connection points while maintaining the securing force function.
Solution Approach 2:
The spring and its mounting structure are merged into an integrated assembly where the spring ends directly engage with the connecting regions. This consolidation eliminates the separate fastener components and their vulnerable junctions, combining the fastening and springing functions into a single durable unit.
2Reliability
If multiple separate fasteners and connecting regions are used for each spring, then the components can be securely fastened, but the assembly process becomes complex and tedious, increasing assembly difficulty
Solution Approach 1:
The patent combines multiple fastening operations into a single integrated spring assembly that engages with connecting regions in one action. The spring design incorporates direct engagement features that eliminate the need for separate fastener installation steps, reducing assembly complexity while maintaining secure fastening.
Solution Approach 2:
The connecting regions are designed with distinct engagement features that allow the spring assembly to be segmented into manageable installation steps, where each spring can be independently and quickly attached to its corresponding connecting regions without interfering with other components.
3Adaptability or versatility
If each movable object is provided with separate springs and fixing members, then the components can function independently, but the overall structure becomes complicated with various and abundant springs
Solution Approach 1:
The spring assembly is designed as a universal component that can perform multiple functions: providing tensile force, securing movable objects, and engaging with different connecting regions. This multi-functional design eliminates the need for separate fixing members and reduces the variety of spring types required, simplifying the overall structure while maintaining independent functionality.
