Solution Overview
Problem
Existing personal care devices fail to effectively reach and soothe itches on hard-to-reach body areas, particularly for individuals with limited flexibility or mobility, and lack versatility for various personal care tasks.
Innovation Solution
A multi-functional personal care device featuring a flexible and adjustable handle with interchangeable heads, allowing for bending into various angles and accommodating different attachments such as scratching brushes, mirrors, and razors for diverse personal care functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rigid stick with a scratching element is used, then the device can reach hard-to-reach areas, but it cannot be bent into various angles and is difficult to use for people with limited flexibility
Solution Approach 1:
The patent applies the dynamics principle by making the wand flexible rather than rigid, allowing it to bend into various angles and positions. This enables users with limited flexibility to easily position the scratching element at different angles to reach hard-to-access areas of the body, resolving the contradiction between ease of operation and adaptability.
Solution Approach 2:
The patent implements this principle by using a flexible wand construction that can bend and conform to different body contours. The flexible material allows the device to adapt to various angles and positions while remaining easy to manipulate, directly addressing the contradiction between operational ease and angular adaptability.
2Adaptability or versatility
If a single-purpose scratching device is used, then the design can be simple, but it lacks versatility for other personal care tasks such as bathing, applying lotions, wiping, viewing, and shaving
Solution Approach 1:
The patent applies the universality principle by designing a multi-functional device with interchangeable heads that can perform various personal care tasks including scratching, bathing, applying lotions, wiping, viewing, and shaving. This allows a single device to replace multiple specialized tools, achieving versatility while maintaining relatively simple device structure through modular design.
Solution Approach 2:
The patent implements segmentation by dividing the device into a handle, flexible wand, and interchangeable heads. This modular structure allows different functional heads to be attached to the same handle and wand assembly, enabling versatility without requiring complex integrated designs for each function.
3Object-affected harmful factors
If existing scratching devices with rigid sticks are used, then the structure is simple, but they only abrasively scrape the skin which makes the itch worse
Solution Approach 1:
The patent applies the local quality principle by providing different head options with varying surface characteristics - some with softer materials for gentle scratching, others with abrasive surfaces for exfoliation, and various textures for different skin conditions. This allows users to select the appropriate local quality for their specific need, reducing harmful skin irritation while maintaining simple overall device structure.

AI summary
An adjustable reach-extending device for manual scratching, cleansing, and shaving comprises a handle, a flexible wand and a detachable head which can be a personal care device. The wand is flexible, and designed to retain the position into which it is formed. The wand terminates in a connector, which connector is designed to receive a complementary end (plug) of the detachable head. A spring-release button within the connector enables the personal care device to be detached from the wand. The personal care device can be a scratching device, a brush, a mirror, a sponge or a razor. The scratching device comprises a plurality of bristles that are attached to a base. The bristles vary in length from short to long, differ in their hardness, whether or not they are mounted in the base at an angle, and the materials from which they are manufactured.
