Solution Overview

Problem

Existing beverage capsules for anhydrous materials like coffee, tea, and cocoa are non-reusable, contribute to environmental waste, and require separate capsules for different beverages, lacking versatility and portability.

Innovation Solution

A manually operated, portable device for assembling capsules using a hollow cup-shaped body and a circular membrane, where the membrane is folded and secured without adhesives, allowing for easy reuse and switching of anhydrous materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If automated manufacturing plants use adhesives or welding to apply membranes to capsules, then assembly reliability is improved, but device complexity and environmental impact worsen

Engineering Contradiction:
Improveassembly reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex automated adhesive application systems or welding equipment with a simple manual mechanical pressing operation. The membrane is secured to the capsule by manual pressure applied through a pressing device, eliminating the need for adhesives, welding equipment, or complex automated systems while maintaining assembly reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The membrane and capsule structure are designed to self-secure through manual pressing without requiring external adhesives or complex bonding mechanisms. The mechanical pressure applied manually creates sufficient friction and deformation to hold the membrane in place, allowing the system to serve itself without additional bonding agents or equipment.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If disposable capsules are used for different beverages, then versatility is improved, but environmental waste worsens

Engineering Contradiction:
Improvebeverage varietyVSAvoidenvironmental waste
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent enables recovery and reuse of the capsule components. The cup-shaped body and membrane are designed to be reusable after simple cleaning, allowing the same physical capsule to be refilled with different anhydrous materials for various beverages. This eliminates the need to discard capsules after single use while maintaining versatility for different beverage types.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The capsule design with reusable cup-shaped body and membrane allows a single physical capsule to serve multiple functions across different beverage preparations. The same capsule structure can contain different anhydrous materials (coffee, tea, cocoa, etc.) through repeated cleaning and refilling, making one capsule universally applicable for various beverages rather than requiring dedicated disposable capsules for each type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If manual assembly devices are used for capsule production, then portability and cost are improved, but assembly precision worsens

Engineering Contradiction:
ImproveportabilityVSAvoidmembrane application precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The membrane is pre-cut and pre-positioned on the capsule before the final pressing operation. The pressing device applies pressure at the correct location and orientation, ensuring proper membrane placement and securing. This preliminary preparation of the membrane and guided pressing action maintains precision even with manual operation and portable device design.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces complex automated positioning and bonding systems with a simplified manual pressing mechanism that maintains sufficient precision through mechanical design. The pressing device's structure guides the application force and position, ensuring accurate membrane securing without requiring sophisticated automated control systems, thereby achieving portability while maintaining adequate manufacturing precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
