Adjustable Handle Apparatus for Remote Sunscreen Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sunscreens are difficult to apply evenly to the back, especially for individuals with limited mobility or arthritic conditions, due to the inaccessibility of the area and the need for rigid, non-adjustable handles that require repetitive arm motion.
Innovation Solution
A self-supporting apparatus that holds a skin-protectant product container, featuring a collar to attach to a vertical surface, a lever arm with adjustable nodules to depress the canister actuator, and a support strap for stability, allowing remote discharge of the product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rigid, non-adjustable handles are used for sunscreen application, then the structure is simple and stable, but the ease of operation deteriorates for users with limited mobility or arthritic conditions
Solution Approach 1:
The patent applies the dynamics principle by making the handle adjustable and flexible rather than rigid. The handle includes an adjustable section that can be modified in length and configuration to accommodate users with different mobility limitations, transforming a static, one-size-fits-all design into a dynamic, adaptable system that moves and adjusts with user needs.
Solution Approach 2:
The handle is segmented into multiple adjustable sections that can be independently configured. This segmentation allows each portion of the handle to be optimized for specific functions and enables users to customize the handle length and angle, breaking down the monolithic rigid structure into modular, reconfigurable components.
2Ease of operation
If the user reaches their arm over and behind their head to apply sunscreen, then the application area is accessible, but the ease of operation deteriorates for those with injuries or arthritic conditions
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of an adjustable extension handle that acts as a mediator between the user's hand and the back surface. This extension allows users to reach difficult areas without performing extreme arm movements, distributing the physical effort across a longer lever arm and reducing strain on joints and muscles.
Solution Approach 2:
The adjustable handle adds a spatial dimension to the application process by extending the reach in multiple directions and angles. Users can configure the handle to reach across the back, between shoulder blades, and in other hard-to-access areas, transforming a single-plane limitation into multi-dimensional accessibility.
3Adaptability or versatility
If repetitive flexion of the elbow is required for application, then the device can reach various body areas, but the ease of operation deteriorates and causes physical strain
Solution Approach 1:
The adjustable handle section provides dynamic adaptability, allowing users to modify the handle configuration for different body areas without repetitive elbow flexion. The handle can be extended, angled, and repositioned to maintain ergonomic arm positions while reaching various locations on the back, eliminating the need for repeated bending motions.
Solution Approach 2:
The patent employs parameter changes by allowing continuous adjustment of handle length, angle, and orientation. These parameter modifications enable the device to adapt to different application locations and user anatomies, maintaining optimal ergonomic parameters throughout the application process rather than requiring fixed, repetitive motions.

AI summary
A spray canister holding apparatus that includes a collar for connecting to a spray canister, made of a non-continuous circular gripping structure having at least one opening along a circumference of the circular gripping structure, a lever arm rotation member, a vertical backing member attached to a posterior continuous portion of the circular gripping structure and extending upwards from the circular gripping structure, and a wire support opening connected to the circular gripping structure. The apparatus also includes a lever arm on the collar, a connecting wire attached to the lever arm, a handgrip attached to the connecting wire, and a discharging nodule appended to the lever arm, where the discharging nodule acts on a spray canister dispenser button.
