Resin Support Member for Straddle Vehicle Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly process of straddle type vehicles, such as motorcycles, is cumbersome due to the need for multiple welding steps to secure electrical components, increasing time and cost.
Innovation Solution
A resin support member connects the left and right pipe sections of the tubular frame, supporting electrical components and eliminating the need for multiple welding steps, while enhancing frame stiffness and providing a space-saving, load-carrying solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple stays are provided and welded to the body frame for each electrical component, then each electrical component can be securely fixed, but the number of welding steps increases, leading to increased assembly time and cost
Solution Approach 1:
Multiple separate stay members are merged into a single integrated resin support member that can secure multiple electrical components simultaneously. This consolidation reduces the number of welding operations from multiple individual welds to a single integrated component installation, directly resolving the contradiction between secure fixation and assembly time.
Solution Approach 2:
The resin support member serves multiple functions: it acts as a structural stiffening element for the tubular frame, provides mounting support for multiple electrical components, and eliminates the need for separate stay members. This multi-functionality addresses both the reliability of component securing and the reduction of assembly steps.
2Manufacturing precision
If multiple welding steps are performed individually for each electrical component, then precise fixation is achieved, but additional costs and time are generated
Solution Approach 1:
The patent combines multiple precision welding operations into a single molded resin component. The resin support member is manufactured as one integrated piece with pre-formed attachment features, eliminating the need for multiple individual welding operations while maintaining precise positioning of electrical components.
Solution Approach 2:
The patent replaces the mechanical welding system with a molded resin system. Instead of using welds to attach multiple separate stay members, the electrical components are secured through the molded structure of the resin support member, which includes integrated attachment features formed during molding. This substitution eliminates complex welding operations while maintaining manufacturing precision.
3Productivity
If a resin support member is used to connect left and right pipe sections, then frame stiffness is increased and assembly is simplified, but the structural load-bearing capacity must be sufficient
Solution Approach 1:
The patent employs a resin support member made of fiber-reinforced composite material that connects the left and right pipe sections of the tubular frame. This composite structure provides sufficient stiffness and load-bearing capacity to replace traditional metal stays while enabling simpler assembly through molding rather than welding. The composite material properties allow the single-piece support member to achieve both assembly simplicity and structural strength.
