Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunscreen application devices are complex, difficult to use, and fail to ensure the correct amount of sunscreen is applied to the body, leading to inadequate protection.
Innovation Solution
A simple, inexpensive sunscreen dosing device made from thermoplastic elastomer with a one-piece construction, featuring a cup with a structured elongation and marks for defined sunscreen amounts, easily attachable to a sunscreen bottle for secure and correct application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing sunscreen application devices are used, then sunscreen application is possible, but the devices are complex and difficult to use
Solution Approach 1:
The patent combines the cup, structured elongation, ears, and through holes into a single integrated dosing device component. This merging of multiple functional elements into one unified structure eliminates the need for separate parts, thereby reducing device complexity while maintaining ease of operation and application functionality.
2Measurement precision
If existing sunscreen application devices are used, then sunscreen application is possible, but the correct amount of sunscreen is not ensured
Solution Approach 1:
The patent incorporates specific local features into the cup structure, including structured elongation with periodic sub-structures, ears with through holes for attachment, and internal markings indicating defined sunscreen amounts. These localized functional elements enable precise measurement of sunscreen quantity without requiring complex overall device architecture, thus achieving measurement precision while keeping device complexity low.
3Ease of manufacture
If a simple one-piece construction is used, then manufacturing is simple and inexpensive, but attachment to body parts or devices may be difficult
Solution Approach 1:
The patent incorporates distinct functional segments within the one-piece construction: the cup for holding sunscreen, the structured elongation for attachment, and the ears with through holes for securing to body parts or devices. This segmentation of functions within a unified structure enables easy manufacturing while maintaining versatile attachment capabilities, as each segment serves its specific purpose without requiring separate components.
4Ease of operation
If the dosing device is made collapsible and flexible, then handling and storage are improved, but structural strength may be compromised
Solution Approach 1:
The patent designs the cup and structured elongation with flexible, collapsible characteristics that allow the device to adapt its shape for convenient handling and compact storage. The dynamic structure can be compressed and expanded while maintaining sufficient structural integrity through the integrated one-piece construction and strategic placement of reinforcement features, thus improving ease of operation without significantly compromising structural strength.

AI summary
A sunscreen dosing device comprises a cup and a structured elongation which is an integral part of the cup. A first ear and a second ear are integral parts of the cup. For attaching the sunscreen dosing device to a body of a sunscreen bottle a free end of the structured elongation can be inserted in the first or the second ear.
