Solution Overview

Problem

Existing coffee capsule pressing tools face issues with alignment, leading to uneven sealing, breakage, and leakage due to misalignment of aluminum foil and capsule shell, resulting in increased costs and environmental waste.

Innovation Solution

A quick self-making tool for coffee capsules with a guide piece and pressing die that ensures coaxial alignment of the sealing film with the capsule shell, using a guide channel and annular gland for even pressing and sealing, and a hoop for secure sealing film placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pressing tool with die holder and pressing die is used to seal the capsule shell, then the sealing function is achieved, but misalignment between aluminum foil and capsule shell occurs, leading to uneven sealing and breakage

Engineering Contradiction:
Improvesealing reliabilityVSAvoidalignment precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

A guide piece is introduced as an intermediary component between the die holder and pressing die. This guide piece includes a guide channel that receives and guides the aluminum foil, ensuring it remains properly aligned with the capsule shell during the pressing process. The guide piece acts as a mediator that coordinates the positioning of multiple components (capsule shell, aluminum foil, die holder, pressing die) to prevent misalignment and achieve even sealing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If disposable coffee capsules are used, then convenience and consistent taste are achieved, but cost increases and environmental waste is generated

Engineering Contradiction:
Improvebrewing convenienceVSAvoidmaterial waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The invention enables recovery and reuse of the capsule shell by providing a pressing tool that can seal the shell for repeated use. Instead of discarding the capsule shell after single use, the guide piece and pressing die allow proper sealing that preserves the shell's integrity for multiple brewing cycles, thereby reducing material waste and lowering long-term costs.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The pressing tool with guide piece enables users to properly seal and reuse their own capsule shells without requiring specialized equipment or complex procedures. The guide channel automatically positions the aluminum foil and guides the pressing die, making the reuse process simple and accessible to ordinary users.

Inventive Principle:
Principle #25Self-service

3Device complexity

If the pressing die directly presses the aluminum foil without guidance, then the pressing operation is simple, but the sealing film and capsule shell become misaligned, causing leakage

Engineering Contradiction:
Improvepressing tool structureVSAvoidsealing effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The guide piece serves as an intermediary component that adds guidance functionality without significantly complicating the overall pressing tool structure. It includes a guide channel that receives the aluminum foil and a guide surface that contacts the capsule shell, ensuring proper alignment during pressing while maintaining a relatively simple overall design.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The guide piece is segmented into functional components: a guide channel for receiving and positioning the aluminum foil, and a guide surface for contacting and positioning the capsule shell. This segmentation allows each component to perform its specific function independently, ensuring proper alignment without requiring a completely complex integrated structure.

Inventive Principle:
Principle #1Segmentation

AI summary

A quick self-making tool for a coffee capsule includes a die holder and a pressing die. A die cavity for containing a capsule shell is formed in the die holder, a sealing film is laid on an opening of the capsule shell, the sealing film seals the opening of the capsule shell through pressing of the pressing die to make the coffee capsule, and a guide piece is arranged on the die holder, and is configured to guide the sealing film to be coaxially aligned with the capsule shell before being pressed and guide up-down vertical movement of the pressing die during pressing. The pressing die evenly press an outer ring of the capsule shell, the sealing effect of the sealing film and the capsule shell is improved, and the situation that the sealing film and the top face of the capsule shell are not combined firmly is avoided.
