Reusable Marker Extension With Replaceable Tip Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing writing implements that offer a choice of colors consume excessive plastic due to the need for multiple markers or complex mechanisms in pens with multiple ink cartridges.
Innovation Solution
A marker kit with a plurality of marker tip holders, a storage member, and an extension member that allows users to select and switch between different marker tips with a secure and efficient mechanism, reducing plastic usage by eliminating the need for multiple markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple markers are provided to give users a choice of colors, then color selection capability is improved, but plastic consumption increases
Solution Approach 1:
The marker system is segmented into two independent parts: a reusable extension member (body) and replaceable marker tip holders. This segmentation allows the plastic-intensive body to be used repeatedly while only the smaller tip holders are replaced, significantly reducing overall plastic consumption while maintaining full color selection capability through multiple tip holder options
Solution Approach 2:
The extension member is designed as a universal component that can accommodate multiple different marker tip holders through the receptacle and securing portion interface. This multi-functionality allows a single extension member body to provide access to various colors by simply changing the tip holder, eliminating the need for multiple complete marker assemblies
2Adaptability or versatility
If a pen body with multiple ink cartridges is used to provide color choice, then color selection capability is improved, but device complexity increases
Solution Approach 1:
The marker system separates the ink storage function (in disposable tip holders) from the writing function (in the reusable extension member), eliminating the need for complex internal mechanisms to manage multiple ink cartridges. Each tip holder is a simple, self-contained unit that attaches and detaches without requiring complex actuation or alignment mechanisms
Solution Approach 2:
The tip holders are designed as disposable components that are simpler and less expensive to manufacture than reusable cartridges. By making the tip holders disposable rather than requiring complex refill or replacement mechanisms for reusable cartridges, the system reduces mechanical complexity while maintaining color selection capability

AI summary
In an aspect, a marker kit is provided, and includes a plurality of tip holders, a storage member, and an extension member. The tip holders each includes a tip holder body having a connecting portion, and a marker tip extending from the body. The storage member includes a base with a plurality of receptacles, each shaped to removably hold one of the tip holders with the connecting portion exposed. The extension member includes an extension member body for grasping. The extension member body has a securing portion and an actuatable member. The securing portion is releasably connectable to the connecting portion of each tip holder for removal from one of the plurality of receptacles. The actuatable member is for disconnecting the securing portion from the connecting portion of the tip holder that is secured to the extension member so as to release the tip holder back into a receptacle.
