Cosmetic Container Charging Electrode Layout for Leak-Free Applicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers with integrated applicator heads require a charging port on the applicator head, leading to bulkiness, usability issues, and design compromises, especially in compact or travel-sized containers, and often result in liquid leakage during charging.
Innovation Solution
The cosmetic container system relocates the charging interface from the applicator head to the container body, using internal conductive pathways to power the applicator head, which remains detachable and compact, with a battery-powered stimulation element for skincare treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a charging port is incorporated into the applicator head, then the applicator head can be recharged, but the size and weight of the applicator head increase, making it bulky
Solution Approach 1:
The charging port is extracted from the applicator head and relocated to the container body. The container body now houses the charging interface and battery, while the applicator head only contains the stimulation element and mating electrical interface, significantly reducing the applicator head's weight and size.
Solution Approach 2:
The system is segmented into two functional modules: the container body (housing charging infrastructure) and the applicator head (housing stimulation elements). This segmentation allows the charging components to be separated from the applicator head, resolving the weight contradiction.
2Adaptability or versatility
If a charging port is incorporated into the applicator head, then the applicator head can be recharged, but the design complexity and sealing challenges increase
Solution Approach 1:
The charging interface is extracted from the applicator head and integrated into the container body structure. This eliminates the need for complex sealing mechanisms around the applicator head's charging port and simplifies the overall design by consolidating charging components in one location.
3Adaptability or versatility
If the applicator head is removed or inverted for charging, then the battery can be recharged, but liquid leakage occurs
Solution Approach 1:
Instead of removing or inverting the applicator head for charging, the charging interface is inverted and placed on the container body. This allows charging to occur in the upright position with the applicator head remaining attached, eliminating leakage risks.
Solution Approach 2:
The container body acts as an intermediary charging station, providing the charging interface and power source. This intermediary structure enables charging without requiring manipulation of the applicator head, maintaining sealing integrity throughout the process.
4Volume of moving object
If the applicator head is made compact for travel, then portability is improved, but incorporating a charging port becomes difficult
Solution Approach 1:
The charging port is taken out from the applicator head and placed in the container body, allowing the applicator head to be minimized in size for travel while retaining full charging capability through the container's integrated charging system.

AI summary
Embodiments of the present invention disclose a cosmetic container comprising a container body and a detachable applicator head. The container body includes a dispensing end and a closed end, and is provided with a first electrical interface at the closed end and a second electrical interface at the dispensing end, electrically connected via internal conductive components. The applicator head includes a mating electrical interface, a rechargeable battery, and a stimulation element, such as a phototherapy lamp. When mounted, the mating electrical interface aligns with the second electrical interface of the container body, allowing the battery to be charged through the first electrical interface provided on the container. The applicator head further includes a coated application surface with a liquid outlet channel and a light-transmitting portion, enabling simultaneous cosmetic dispensing and light-based therapy to improve user convenience and skincare effectiveness.
