Foamed Oral Hygiene Handle Structure for Lightweight Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hygiene products, particularly oral hygiene products, face challenges in achieving a balance between material efficiency, weight, and ergonomics, with a need for improved grippability and reduced weight without compromising on voluminousness and ecological sustainability.
Innovation Solution
The hygiene product incorporates a base body connected to a volume body, partially forming the application and/or handle unit, produced through a foaming process, using a combination of hard and soft components, including foamed materials, to enhance ergonomics and reduce weight while maintaining a voluminous and lightweight design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the hygiene product is made with traditional solid materials to ensure durability and structure, then strength and stability are improved, but weight increases and ergonomics deteriorate
Solution Approach 1:
The patent applies foamed materials with porous structure to create the hygiene product. The foam structure provides lightweight properties while maintaining sufficient structural strength through the cellular architecture. The base body and volume body are both made of foamed materials with appropriate density and cell structure to balance weight reduction and strength requirements.
Solution Approach 2:
The patent uses composite construction by combining foamed materials for the base body and volume body. The foamed material composition provides both structural integrity and weight reduction, creating a composite structure that optimizes the strength-to-weight ratio for improved ergonomics without compromising durability.
2Ease of operation
If the volume body is made larger to improve ergonomics and grippability, then ease of operation is improved, but material input and weight increase
Solution Approach 1:
The volume body is constructed from foamed material that provides high volume with low material density. The porous foam structure allows the product to have a large, ergonomic volume for comfortable gripping while using minimal actual material, thus reducing material input and waste without compromising grippability.
3Ease of manufacture
If foamed material is used to reduce weight and material input, then ease of manufacture and sustainability are improved, but manufacturing precision and connection reliability may worsen
Solution Approach 1:
The patent merges the base body and volume body into an integrated structure where the volume body is molded directly onto the base body. This combining approach simplifies manufacturing by reducing assembly steps and potential connection failures, while the foamed material properties allow for effective bonding between the two components through direct molding processes.
