Applicator Head With Thermal Member And Recessed Concavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic and medicinal applicator heads fail to provide a thermal treatment effectively while being economical to manufacture and aesthetically pleasing, lacking a large surface area and comfort in use.
Innovation Solution
An applicator head comprising a first and second thermal material member with a convex applicator surface and recessed concavity, where the second member has higher thermal effusivity to provide a thermal sensation, facilitating easy product distribution and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single-material applicator head is used, then manufacturing is simple and economical, but thermal treatment effectiveness is insufficient
Solution Approach 1:
The applicator head is divided into two distinct members: a first applicator member made of a first material and a second applicator member made of a second material. This segmentation allows each member to be optimized for different functions - one for product delivery and one for thermal treatment - thereby improving thermal treatment effectiveness while maintaining manufacturing simplicity through modular construction.
Solution Approach 2:
The applicator head combines two different materials in a composite structure, where the first applicator member and second applicator member are coupled together. This composite approach enables the integration of materials with different thermal properties, enhancing the overall thermal treatment effectiveness without requiring a single complex material.
2Area of stationary object
If a large surface area applicator head is designed, then thermal treatment coverage is improved, but manufacturing complexity increases
Solution Approach 1:
The large applicator surface is segmented into two members, each contributing to the overall surface area. This allows the large surface area to be achieved through the combination of two simpler, more manufacturable components rather than a single complex piece.
3Quantity of substance
If a recessed concavity is added to collect fluid product, then product retention is improved, but manufacturing complexity increases
Solution Approach 1:
The recessed concavity is integrated into the second applicator member, merging the product collection function with the thermal treatment member. This consolidation allows product retention to be achieved without adding a separate collection component, thereby minimizing manufacturing complexity.

AI summary
An applicator head intended to be associated with a cosmetic dispensing package for dispensing and applying a fluid product. The applicator head includes a first applicator member and a second applicator member coupled to one side of the first applicator member. The second applicator member made of a material capable of holding and retaining a thermal charge. An upper surface of the applicator head defines an applicator surface adapted to apply and dispense the fluid product. The applicator surface is angled with respect to a longitudinal axis of the applicator head. A recessed concavity is formed on the applicator surface and a discharge opening is disposed within the recessed concavity. A first portion of the recessed concavity lies on the first applicator member and a second portion of the recessed concavity lies on the second applicator member.
