Solution Overview

Problem

Existing tissue and wet wipe dispensers face challenges in preventing contamination of remaining wipes when individual tissues are removed and do not offer eco-friendly and space-saving disposal options.

Innovation Solution

A tissue dispenser system with a removal device featuring a closure cap, a removal part, and a flexible connecting web, which includes a cross-shaped removal opening with upwardly curved holding corners to prevent retraction and a detachable attachment to a fastening frame, allowing for easy removal and reattachment for refilling, and using a stand-up bag for the container to reduce material usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a removal opening is provided in the lid through which wipes can be removed, then individual wipe removal is enabled, but contamination of remaining wipes occurs

Engineering Contradiction:
Improveindividual wipe removalVSAvoidcontamination of remaining wipes
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The removal opening is segmented into two functional parts: a first removal opening in the removal device for individual wipe removal, and a second removal opening in the mounting frame for filling. The removal device acts as a segmentation barrier that isolates the storage compartment from the external environment during wipe removal, preventing contamination while enabling easy access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The removal device serves as an intermediary component between the wipes in the container and the user. It includes a closure cap that can be opened for removal and closed for protection, acting as a mediator that enables wipe removal while maintaining contamination protection of the remaining wipes in the storage compartment.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the lid is removed to take out wipes, then easy access is achieved, but contamination of remaining wipes occurs

Engineering Contradiction:
Improveaccess to wipesVSAvoidcontamination of remaining wipes
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The lid system is segmented into a mounting frame with a second removal opening for filling and a removal device with a first removal opening for individual wipe removal. This segmentation allows access without complete lid removal, maintaining protection while enabling operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The removal device functions as an intermediary structure that provides controlled access to wipes. The closure cap acts as a movable intermediary element that can be opened for removal and closed for protection, eliminating the need to remove the entire lid while preventing contamination.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If a closure cap with connecting strap is used to close the removal opening, then contamination protection is improved, but device complexity increases

Engineering Contradiction:
Improvecontamination protectionVSAvoidstructure of removal device
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The closure cap is merged with the removal device in a unitary construction, eliminating the need for separate connecting straps or fastening mechanisms. The closure cap is directly integrally formed with the removal device, simplifying the overall structure while maintaining effective closure functionality for contamination protection.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The removal device is designed as a multi-functional universal component that combines the functions of a removal opening, a closure mechanism, and a mounting interface. The closure cap integrates multiple functions (closure, structural support, and mounting attachment) into a single element, reducing overall device complexity.

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

4Stability of the object's composition

If a non-detachable removal device is used, then structural stability is improved, but refilling becomes difficult

Engineering Contradiction:
Improvestructural stabilityVSAvoidrefilling capability
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The removal device incorporates dynamic characteristics through its detachable mounting connection to the mounting frame. This allows the removal device to transition between a stable attached state during wipe removal and a detached state during refilling operations, providing both structural stability and refilling ease through state change.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting connection is segmented into detachable components that allow easy separation of the removal device from the mounting frame. This segmentation enables the removal device to be detached for refilling operations and reattached to maintain structural stability during use, balancing both requirements.

Inventive Principle:
Principle #1Segmentation

5Quantity of substance

If traditional buckets are used for storing wipes, then storage capacity is sufficient, but disposal is not space-saving and environmentally friendly

Engineering Contradiction:
Improvestorage capacityVSAvoiddisposal volume and environmental impact
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The container is designed as a disposable short-living object made from flexible, lightweight material that can be easily discarded after use. This eliminates the need for cleaning and sterilizing traditional buckets, significantly reducing disposal volume and environmental impact while maintaining adequate storage capacity during the product's service life.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The container is constructed from flexible shell material that conforms to the wipes it contains. This flexible membrane structure provides sufficient storage capacity while using minimal material, resulting in compact disposal volume and reduced environmental impact compared to rigid traditional buckets.

Inventive Principle:
Principle #30Flexible shells and thin films
