Capsule Cap Spiral Guide Torque Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capsule caps for beverage containers are prone to premature addition of additives due to external shocks, fail to prevent spoilage of drinking water and additives, and have difficulties in mixing and cutting mechanisms, especially with powder additives.
Innovation Solution
A capsule cap design featuring a lower coupling unit with a seal and a cutting unit with a spiral guide, an upper coupling unit with a spiral pressing guide, and a vertically formed cutting unit guide groove, which allows for separate storage of water and additives, easy mixing by changing torque to straight force, and enhanced sealing to prevent spoilage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sealing sheet is made thin to allow easy cutting, then cutting ease is improved, but the sealing sheet becomes easily torn by external shock and additives are unexpectedly added
Solution Approach 1:
The sealing sheet is divided into two functional layers: a thin easy-to-cut sealing sheet (first sealing sheet) and a thick protective reinforcement sheet (second sealing sheet). The first sealing sheet enables easy cutting while the second sealing sheet provides structural strength to prevent tearing from external shocks, thus resolving the contradiction between cutting ease and sealing integrity.
Solution Approach 2:
The first sealing sheet is nested within or combined with the second sealing sheet, creating a composite structure where the thinner cutting-friendly sheet is protected by the thicker reinforcement sheet. This nested arrangement allows the thin sheet to be cut easily while the thick sheet prevents accidental tearing.
2Reliability
If the sealing sheet is made thick to prevent tearing, then sealing sheet integrity is improved, but the additive is not mixed to the beverage due to increased thickness
Solution Approach 1:
The sealing system is segmented into a thin first sealing sheet for easy cutting and additive release, and a thick second sealing sheet for structural protection. This segmentation allows the thin sheet to facilitate easy additive mixing while the thick sheet maintains sealing integrity.
3Ease of operation
If the push portion is exposed to the outside for easy operation, then ease of operation is improved, but the push portion is frequently unexpectedly pressed and additives are unexpectedly added
Solution Approach 1:
The push portion is nested within the cap body rather than being exposed. The user must first open the cap to access the push portion, which prevents accidental pressing while maintaining operational ease through the sequential access design.
Solution Approach 2:
The cap structure requires the user to perform a preliminary action (opening the cap) before accessing the push portion. This preliminary step prevents premature or accidental additive release by making the push portion inaccessible until the cap is intentionally opened.
4Reliability
If the sealing sheet is made resistant to high pressure and high temperature for sterilization, then sterilization resistance is improved, but the sealing sheet cannot be easily cut and separates
Solution Approach 1:
The sealing function is divided between two sheets: the first sealing sheet made of easily cuttable material that separates cleanly after sterilization, and the second sealing sheet made of high-temperature resistant material that maintains structural integrity during sterilization and prevents premature separation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents spoilage of water and additives, allows for easy mixing of various beverages, and ensures the cutting unit remains sealed and functional, improving user convenience and the overall performance of the capsule cap.
Implementation Method 1
allows for opening the beverage container and dropping the additive at the same time by changing torque into straight force using spiral guides

AI summary
A capsule cap for a beverage container of the present invention includes: a cylindrical lower coupling unit (10) keeping an additive (A) therein; a cutting unit (20) having a cylindrical cutting body (21) inserted in a lower body (11) and vertically moving down to cut a seal (12) so that the additive (A) drops; and an upper coupling unit (30) disposed over the lower coupling unit (30) to be turned and vertically move the cutting unit (20), in which drinking water contained in the beverage container an additive are separately kept, so the drinking water and the additive are prevented from spoiling. Further, spiral guides are formed, so torque is easily changed into straight force, thereby achieving easy cutting and opening.
