Dual-Engaging Connecting Element for Stationary Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Common push-up tubes for items like lipsticks and highlighters are often rendered useless due to misplaced or loose closure caps, leading to inefficient use and increased inventory management, as they require unique closure mechanisms and are prone to evaporation, especially for highlighters.
Innovation Solution
A connecting element with dual engaging means that secures a glue stick and highlighter together, providing airtight and circular closing mechanisms, preventing rolling and evaporation, and allowing upright or inverted positioning, utilizing a thermoplastic material with a conical partition and cylindrical groove for secure sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate closure caps are used for glue stick and highlighter, then each item can have its specific closure mechanism, but the closure caps are easily misplaced and rolled away
Solution Approach 1:
The patent combines the closure cap for the glue stick with the cap for the highlighter into a single integrated closure assembly. This unified closure mechanism eliminates the problem of separate small caps being misplaced or rolled away, while still providing the distinct closure functions needed for both items through the dual engaging means design.
Solution Approach 2:
The closure cap is designed with dual engaging means that allow it to serve multiple functions: it acts as a closure for the glue stick through one engaging mechanism and simultaneously serves as a closure for the highlighter through another engaging mechanism. This multi-functional design ensures that a single cap structure can reliably secure both different types of articles.
2Ease of operation
If highlighter cap is loose to allow easy access, then opening is convenient, but ink evaporates and pen goes dry
Solution Approach 1:
The closure mechanism incorporates a sealing feature that prevents ink evaporation by creating an airtight or vapor-tight seal when the cap is closed. The dual engaging means ensure the cap is securely positioned to maintain this seal, preventing the harmful evaporation effect before it can occur during storage or non-use periods.
3Ease of operation
If glue stick is placed horizontally in pen holder, then it is easily accessible, but it blocks other stationary items and is difficult to pick up
Solution Approach 1:
The patent enables the glue stick to be positioned vertically or at an angled orientation within the pen holder through the dual engaging means mechanism, rather than being restricted to horizontal placement. This dimensional change in positioning allows the glue stick to be easily accessible while not blocking other stationary items in the pen holder.
4Adaptability or versatility
If dual engaging means are integrated, then one closure serves two items, but the structure becomes more complex
Solution Approach 1:
The closure mechanism is divided into distinct functional segments: one engaging means for the glue stick and another engaging means for the highlighter. This segmentation allows each part of the closure to perform its specific function independently while being integrated into a unified structure, managing complexity through functional decomposition.

AI summary
A connecting element with a dual engaging means that allows two different items of daily use to be connected together as a single article for the day to day convenience of the user is disclosed. The connecting element has the dual engaging means to secure two articles at a time. The connecting element is used as an engaging means and also as a closing means for respective articles. The connecting element has different geometric features at its either ends so that it is used as an engaging means and a closing means for the articles with different geometric features.
