Innovation Solution

A motorized callus remover with a hollow handle, oscillating motor, and a head with catch apertures that uses a sandpaper sheet to remove calluses while a vacuum collects skin particles, allowing for adjustable speed and precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If manual callus removal methods are used, then simplicity is maintained, but effectiveness and precision in removing calluses deteriorates

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent replaces manual mechanical scraping with an automated oscillating motor-driven sandpaper sheet mechanism. The motorized oscillation system provides consistent, controlled motion that effectively removes calluses without requiring manual dexterity, thereby improving effectiveness while maintaining ease of use through automation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs oscillating vibration of the sandpaper sheet attached to the head, driven by an electric motor. This mechanical vibration enhances the callus removal efficiency by creating friction and abrasion forces that effectively exfoliate dead skin cells, providing superior performance compared to static manual methods.

Inventive Principle:
Principle #18Mechanical vibration

2Device complexity

If traditional callus removers are used, then device complexity is low, but ability to collect skin particles deteriorates

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The patent incorporates a vacuum system with a collection cavity that uses negative pressure to suction and collect skin particles generated during callus removal. This pneumatic mechanism efficiently captures debris, keeping the treatment area clean and preventing particle dispersion, while adding only moderate complexity to the device.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Device complexity

If fixed-speed callus removers are used, then device complexity is reduced, but user comfort and precision deteriorates

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent implements a variable speed control system that allows users to adjust the oscillation speed of the motor according to their comfort and precision needs. This dynamic adjustment capability enables users to select appropriate speeds for different callus thicknesses and sensitivity levels, enhancing ease of operation without excessive complexity.

Inventive Principle:
Principle #15Dynamics
