Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle covers with hinges for charging ports require significant space and are prone to damage, posing a risk of injury to riders.
Innovation Solution
A magnetic cover system for the charging port that eliminates the need for hinges by using magnetic force for fixation, allowing tool-free attachment and detachment, and incorporating a sliding bearing for a pivot joint without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinge construction is used to mount the cover, then the cover can be opened and closed, but the hinge requires a lot of space and can be damaged by excessive force
Solution Approach 1:
The patent replaces the mechanical hinge system with a magnetic field-based closure system. Magnets embedded in the cover and charging port housing generate magnetic attraction force to automatically close and hold the cover, eliminating the need for mechanical hinges, pins, and associated mounting structures. This substitution of mechanical components with a magnetic field-based system resolves the space constraint while maintaining ease of operation.
2Ease of operation
If a hinge construction is used to mount the cover, then the cover can be opened and closed, but the hinge can be damaged by excessive force such as snagging
Solution Approach 1:
The patent replaces the mechanical hinge system with a magnetic field-based closure system. Magnets embedded in the cover and charging port housing generate magnetic attraction force to automatically close and hold the cover, eliminating the need for mechanical hinges, pins, and associated mounting structures. This substitution of mechanical components with a magnetic field-based system resolves the space constraint while maintaining ease of operation.
3Area of stationary object
If a magnetic cover system is used to eliminate hinges, then installation space is reduced and damage from excessive force is prevented, but additional magnetic components are required
Solution Approach 1:
The patent integrates magnets into existing structural components - specifically embedding magnets in the cover and embedding magnets in the charging port housing. These magnetic components serve dual purposes: they provide the closing force and also function as integral parts of the housing structure. This multi-functional integration approach minimizes additional complexity while achieving the space-saving benefits.
