Lotion Dispensing Device With Pumping Module And Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lotion applying devices are inefficient in reaching and applying moisturizers or sunscreens to hard-to-reach areas without making a mess.
Innovation Solution
A device comprising a transparent plastic tube with a reservoir, a disc-shaped plate, and a pumping module, where a pad with a channel is used to transfer lotion from the tube to the skin surface, allowing precise application to hard-to-reach areas with minimal mess.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional lotion bottle is used, then the lotion can be stored, but it cannot be applied to hard-to-reach areas without making a mess
Solution Approach 1:
The device segments the lotion application system into distinct functional components: a reservoir for storage, a pumping module for controlled dispensing, a channel for transport, and a pad for application. This segmentation allows each component to perform its specific function efficiently, enabling precise application to hard-to-reach areas while preventing mess through controlled lotion flow.
Solution Approach 2:
The channel acts as an intermediary element that connects the pumping module to the pad, serving as a controlled pathway for lotion transport. This intermediary structure ensures lotion is delivered precisely where needed on the pad, preventing uncontrolled flow and mess during application to difficult-to-reach areas.
2Measurement precision
If a manual application method is used, then the device structure can be simple, but the application precision and control are poor
Solution Approach 1:
The pumping module provides self-service functionality by automatically controlling lotion dispensing without requiring manual squeezing or pouring. The user simply activates the pump, which then precisely controls the lotion flow through the channel to the pad, achieving high application precision while maintaining relatively simple device structure.
Solution Approach 2:
The device replaces imprecise manual mechanical application (hand-squeezing bottles) with a controlled pumping mechanism. This substitution provides precise metering and control of lotion delivery, significantly improving application precision while adding only moderate structural complexity through the integration of the pump, channel, and pad system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables independent and mess-reduced application of lotions to hard-to-reach areas, such as the back, by using a pumping mechanism that delivers lotion directly to the skin surface through a pad, enhancing user convenience and hygiene.
Implementation Method 1
The pumping module is configured to selectively transfer the lotion from the reservoir through the outlet pipe and the channel to the front face of the pad

AI summary
A lotion dispensing and applying device for hard to reach areas includes a tube that define a reservoir, which is configured to position a lotion. A plate and a pumping module are coupled to a first end and second end of the tube, respectively. A pad is coupled to and substantially covers a first face of the plate. A channel extends from a front face of the pad through the pad and the plate to the tube. An outlet pipe is coupled to the pumping module and extends through the tube to the plate so that the pumping module is fluidically coupled to the channel. The pumping module is configured to selectively transfer the lotion from the reservoir through the outlet pipe and the channel to the front face of the pad so that the lotion is applicable to a skin surface.
