Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nose hair trimmers suffer from unstable blade components due to machining errors and deviations, leading to vibration and noise during operation.
Innovation Solution
A nose hair trimmer head design featuring a moving blade component with two mirrored blades that can translate and rotate relative to a guiding column, supported by spring pieces, allowing adaptation to uneven surfaces and reducing vibration and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the blade is fixed or cannot move freely, then the structure is simple, but the blade becomes unstable during rotation causing vibration and noise
Solution Approach 1:
The blade is designed to move dynamically within the blade holder rather than being fixed. The blade can translate and rotate relative to the blade holder, allowing it to adapt to deviations in the trimmer head cover inner wall and maintain stable contact during rotation, thereby reducing vibration and noise while keeping the overall structure relatively simple.
2Ease of manufacture
If the blade is fixed, then the manufacturing is easier, but machining errors cause the blade to be unable to adjust itself leading to instability
Solution Approach 1:
The blade is designed to self-adjust within the blade holder through translation and rotation movements. This self-service mechanism allows the blade to automatically compensate for machining errors and deviations in the trimmer head cover inner wall during operation, eliminating the need for complex pre-adjustment mechanisms while maintaining alignment precision.
3Device complexity
If the blade cannot move freely, then the device complexity is low, but vibration and noise increase during operation
Solution Approach 1:
The blade is designed to move dynamically within the blade holder rather than being fixed. The blade can translate and rotate relative to the blade holder, allowing it to adapt to deviations in the trimmer head cover inner wall and maintain stable contact during rotation, thereby reducing vibration and noise while keeping the overall structure relatively simple.
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 design ensures smoother operation by allowing blades to adjust to deviations, significantly reducing vibration and noise during rotation.
Implementation Method 1
a first spring piece, wherein the first spring piece is arranged in the sliding groove, and both ends of the first spring piece are respectively in contact with the two blades to push the blade edge of the two blades to respectively abut against the inner side walls of the trimmer head cover

AI summary
A nose hair trimmer head includes a trimmer head shell, a trimmer head cover and a moving blade component, wherein the moving blade component includes a blade holder, a blade and a first spring piece. The first spring piece is arranged in the sliding groove of the blade holder. Both ends of the first spring piece are respectively in contact with the two blades to push the blade edges of the two blades to respectively abut against the inner side wall of the trimmer head cover. Adopting the above technical solution can realize the basic functions of the nose hair trimmer head while featuring a more stable structure and reducing vibration and noise.
