Surgical Hair Clipper Suction Attachment Nozzle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction attachments for surgical hair clippers can lead to improper use, such as raking of blades against the skin, and are inefficient in removing hair clippings, potentially leaving hair behind and causing allergic reactions due to adhesive use.
Innovation Solution
A suction attachment for surgical hair clippers that includes a clipper attachment connected to the clipper body and a nozzle structure extending distally to an end located no more than ten millimeters proximal of the guide surface plane, ensuring proper technique and efficient hair removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adhesive tape is used to remove hair clippings, then hair removal is achieved, but efficiency is reduced and allergic reactions may occur
Solution Approach 1:
The patent replaces the adhesive-based mechanical removal system with a vacuum suction system. The vacuum device creates negative pressure to lift and remove hair clippings from the skin surface, eliminating the need for adhesive tape and its associated harmful effects while maintaining or improving removal efficiency.
Solution Approach 2:
The patent employs pneumatic principles by using a vacuum suction mechanism to remove hair clippings. The vacuum device creates a pressure differential that draws hair clippings away from the skin, providing an effective non-adhesive removal method that avoids allergic reactions.
2Productivity
If vacuum nozzle is removed from blades, then hair clippings can be collected, but improper use such as raking blades against skin becomes possible
Solution Approach 1:
The patent merges the vacuum nozzle with the blade assembly structure, integrating the suction function directly into the cutting mechanism. This combination ensures that the vacuum nozzle remains in its proper position during operation, preventing improper use while maintaining effective hair clipping and collection.
Solution Approach 2:
The patent uses the blade assembly as an intermediary structure that simultaneously performs cutting and positions the vacuum nozzle correctly. The blade assembly acts as a mediator between the cutting function and the suction function, ensuring proper technique by maintaining the nozzle in the correct position relative to the skin and blades.
3Ease of operation
If nozzle structure extends distally, then proper technique is reinforced, but the end may contact skin area requiring precise positioning
Solution Approach 1:
The patent applies local quality by making the distal end of the nozzle structure specifically designed to contact the skin area, while the rest of the nozzle maintains its suction function. This localized skin-contacting feature provides proper technique guidance without requiring the entire nozzle to be precisely positioned, focusing precision only where needed for skin contact.
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
The suction attachment enhances proper technique during hair removal, improves efficiency by collecting hair clippings effectively, and reduces the risk of skin irritation by eliminating the need for adhesive tapes.
Implementation Method 1
Vacuum devices have been introduced where a vacuum nozzle is used to pick up hair clippings

AI summary
A surgical hair clipper assembly includes a clipper body and a blade assembly connected to the clipper body. The blade assembly includes a moveable blade configured to reciprocate to remove hair from a skin area and a blade housing that houses the moveable blade. The blade housing has a guide surface that faces the skin area during a hair removal process. A suction attachment includes a clipper attachment connected to the clipper body and a nozzle structure connected to the clipper attachment and extending distally to an end. The end is located no more than about ten millimeters proximal of a plane defined by the guide surface.
