Chain Guide With Separate Attachment Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chain guides require increased space and material usage to achieve necessary strength, rigidity, and durability, leading to higher manufacturing costs and reduced versatility due to the integration of attachment portions with the guide shoe and base member, which complicates manufacturing and design optimization.
Innovation Solution
The chain guide design separates the attachment portion from the guide shoe and base member, allowing for different materials and shapes to be selected for each component, reducing manufacturing steps and material waste, and enabling easier adaptation to various applications by using a separate attachment member that can be fixed to either or both the guide shoe and base member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the chain guide is formed entirely of low-friction resin material, then the friction resistance is reduced, but the strength and rigidity are insufficient requiring increased thickness and size
Solution Approach 1:
The chain guide combines resin material for the guide shoe (providing low friction) with metal base member (providing strength and rigidity). This composite structure allows each material to perform its optimal function without requiring increased thickness for compensation.
2Strength
If the attachment portions are integrated with the guide shoe and base member, then the structural strength is improved, but the manufacturing complexity and material waste increase
Solution Approach 1:
The attachment portions are separated into independent components that can be manufactured separately from the guide shoe and base member. This segmentation allows each component to be optimized for its specific function and manufactured using the most appropriate process, reducing overall manufacturing complexity and material waste.
Solution Approach 2:
The attachment portions are combined with the guide shoe and base member through standardized connection interfaces. This merging approach maintains structural strength while allowing independent manufacturing and optimization of each component.
3Adaptability or versatility
If the base member is formed by bending the same metal plate at multiple positions, then the attachment portions are integrated, but the number of manufacturing steps increases
Solution Approach 1:
The base member and attachment portions are segmented into separate components. The base member can be formed from a simple flat plate without complex bending operations, while attachment portions are manufactured separately and assembled, significantly reducing the number of manufacturing steps.
4Adaptability or versatility
If the guide shoe is made detachable from the base member, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The detachable connection interface between guide shoe and base member is designed as a universal standardized connection that can accommodate different configurations and applications. This universal interface enables adaptability without proportionally increasing device complexity.

AI summary
There is provided a chain guide that reduces a space occupied by the chain guide in an engine room while maintaining required strength, rigidity, and durability with a simple configuration, reduces the number of manufacturing steps and the waste of a material, does not require a structure that permits an error, prevents increases in vibration and noise during use, and reduces the burden of a maintenance operation. The chain guide has a guide shoe and a base member that reinforces the guide shoe, and an attachment portion includes an attachment member that is provided separately from the guide shoe and the base member and can be fixed to at least one of the guide shoe and the base member or both of the guide shoe and the base member.
