Solution Overview

Problem

Existing diffusers for pressurized containers are constrained by the material choice for the outlet conduit, which impacts manufacturing costs and rarely considers optimizing the quality and volume of materials, limiting the ability to choose different materials for the outlet duct and base body based on their specific properties.

Innovation Solution

A diffuser design where the outlet conduit and base body are made from different materials, with the outlet conduit using a high-quality, virgin or food-grade material and the base body using recycled material, allowing for separate manufacturing and optimization of material qualities and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the outlet conduit is made from high-quality virgin or food-grade material to ensure chemical suitability for the product, then the product safety and chemical compatibility are improved, but the manufacturing cost increases

Engineering Contradiction:
Improvechemical suitabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The diffuser is divided into two separate components: the outlet conduit and the base body. The outlet conduit is manufactured from high-quality virgin or food-grade material to ensure chemical suitability, while the base body is made from recycled material. This segmentation allows each component to be optimized for its specific function and material requirements, reducing overall manufacturing costs while maintaining product safety.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different material qualities are applied to different parts of the diffuser based on their specific functional requirements. The outlet conduit, which is in direct contact with the product, uses high-quality material with appropriate chemical properties, while the base body, which does not contact the product, uses cost-effective recycled material. This local quality approach optimizes both safety and cost.

Inventive Principle:
Principle #3Local quality

2Ease of manufacture

If the outlet conduit and base body are made from the same material to simplify manufacturing, then the manufacturing process is simplified, but the ability to optimize material selection for each component is lost

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidmaterial selection flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The diffuser is segmented into two independently manufacturable components: the outlet conduit and the base body. This segmentation enables each component to be manufactured from the most appropriate material for its specific function, allowing the outlet conduit to use food-grade materials while the base body uses recycled materials, thus optimizing both material selection flexibility and manufacturing efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The outlet conduit is designed as a universal component that can be manufactured from various high-quality materials (virgin plastic, food-grade plastic) depending on the specific product requirements, while the base body serves as a universal housing that can be made from different recycled materials. This multi-functionality approach allows flexibility in material selection for each component.

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

3Ease of manufacture

If recycled material is used for the base body to reduce costs and improve sustainability, then manufacturing cost and environmental impact are improved, but the material choice is constrained by availability and quality consistency

Engineering Contradiction:
Improvemanufacturing costVSAvoidmaterial consistency
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The diffuser is segmented so that the base body can be independently manufactured from recycled materials without affecting the quality of the outlet conduit. This segmentation isolates the material consistency requirements to only the outlet conduit (which uses virgin or food-grade material), allowing the base body to freely utilize cost-effective and sustainable recycled materials with varying qualities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different material quality standards are applied locally to different components. The outlet conduit requires consistent, high-quality material to ensure chemical suitability, while the base body can accommodate the natural variations in recycled materials since it does not contact the product. This local quality differentiation resolves the conflict between cost and material consistency.

Inventive Principle:
Principle #3Local quality

AI summary

Disclosed is a dispenser (100) for a pressurised container (20) provided with a valve (30), provided with a base body (110) having a finger tab (130) intended to be pressed by the user in order to actuate the valve (30), and having an output opening (114) intended for the output of a product contained in the container (20). The dispenser (100) is also provided with an output pipe (120) placed in the base body (110), which output pipe (120) has a first end (121) configured to cooperate with the valve (30) of the pressurised container (20), and a second end (122) configured for the output of the product contained in the pressurised container (20). The output pipe (120) is coupled to the base body (110) so that the second end (122) of the output pie is substantially facing the output opening (114) of the base body (110). At least one part of the base body (110) is manufactured from recycled material. The output pipe (120) is manufactured from a material different from the recycled material.
