Motorized Back Lotion Applicator With Massage Dispensing Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lotion applicators do not efficiently dispense lotion through a hand-shaped massaging device to hard-to-reach areas like the back, lacking features such as dispensing openings and motorized operation.
Innovation Solution
A motorized lotion applicator with a hand-shaped dispenser, protruding members for massage, and a refillable compartment, powered by a motor and batteries, that dispenses lotion through openings while massaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing lotion applicators are used, then they can apply lotion to the back, but they cannot efficiently dispense lotion through a hand-shaped massaging device with protruding members
Solution Approach 1:
The patent combines the lotion dispensing function with the massaging function into a single integrated device. The hand-shaped applicator head includes both protruding members for massage and dispensing openings for lotion application, allowing simultaneous massaging and lotion dispensing to the back without requiring separate devices
Solution Approach 2:
The applicator head serves multiple functions: it acts as a massaging tool with protruding members, a lotion dispenser with dispensing openings, and a guide for precise application. This multi-functional design increases adaptability while maintaining ease of use through a single unified device
2Productivity
If a motorized system is added to dispense lotion, then lotion dispensing efficiency improves, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical lotion dispensing mechanisms with a simpler motor-driven pump system. The pump is activated by a foot pedal, eliminating the need for manual hand cranking or complex valve mechanisms, thereby improving dispensing efficiency while keeping the overall device complexity manageable
Solution Approach 2:
The foot pedal serves as an intermediary control mechanism that simplifies the user interface for operating the motorized pump. Instead of requiring direct hand operation of the pump mechanism, the user controls lotion dispensing through the foot pedal, reducing the perceived complexity while maintaining efficient operation
3Adaptability or versatility
If protruding members are added for massage function, then massaging capability improves, but manufacturing cost increases
Solution Approach 1:
The applicator head incorporates a porous or perforated structure with multiple small dispensing openings integrated into the hand-shaped form. This design allows the massaging surface and lotion dispensing function to be combined in a single molded component, adding massaging capability through simple geometric features rather than complex assembled parts, thereby controlling manufacturing costs
