Modular Magnetic Multiple Tool for Bicycle Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple tools for motorcycle and bicycle maintenance are heavy, inconvenient to carry, and lack a practical way to bundle additional necessary tools and accessories.
Innovation Solution
A lightweight multiple tool design featuring a central frame with radially attached tool bodies that magnetically connect, allowing for easy engagement and disengagement of tools, including a chain breaker, tire inflator, and storage containers, enabling the carrying of additional implements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional steel bolts and frame members are used for multiple tool construction, then structural strength and stability are ensured, but the tool becomes heavy and inconvenient to carry
Solution Approach 1:
The multiple tool is divided into separate modular components (Y-tool bodies and implements) that can be independently carried and reconfigured. Each Y-tool body can function independently or combine with others, allowing users to carry only the necessary components for specific tasks rather than a complete heavy set.
Solution Approach 2:
Implements are designed to nest within or attach to Y-tool bodies when not in use. The implements can be stored in the peripheral seats or attached to the frame, creating a compact nested configuration that reduces carrying bulk and weight while maintaining structural integrity when assembled.
2Adaptability or versatility
If multiple separate Y-tools are carried to provide comprehensive tool functionality, then tool versatility is improved, but portability and safety deteriorate due to size and potential injury from exposed tips
Solution Approach 1:
Multiple Y-tool bodies and implements are merged into a single integrated multiple tool assembly with a common frame structure. This consolidation provides comprehensive tool versatility in one unit while enclosing all implements within the frame structure, eliminating exposed tips and safety hazards associated with carrying separate tools.
Solution Approach 2:
The frame and Y-tool bodies are designed with universal interfaces and interchangeable implements, allowing a single multiple tool assembly to perform multiple functions. The same frame can accommodate different Y-tool bodies and implements based on maintenance needs, providing versatility without requiring multiple separate tool sets.
3Ease of operation
If implements are permanently fixed to the frame, then structural stability is improved, but ease of operation deteriorates due to difficulty in engaging and disengaging tools
Solution Approach 1:
The connection between implements and the frame transitions from static permanent fixation to dynamic removable attachment. Implements can be easily engaged and disengaged from the frame and Y-tool bodies during operation, while magnetic attraction and mechanical features maintain stable positioning when assembled, providing both ease of operation and structural stability.
Solution Approach 2:
Traditional mechanical fastening systems (screws, bolts, clips) are replaced with magnetic attraction mechanisms for holding implements to the frame and Y-tool bodies. This substitution provides easy engagement and disengagement through simple approach and separation movements while maintaining secure stable attachment during use, improving ease of operation without sacrificing structural stability.
