Beard Trimmer Stepless Comb Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beard trimmers lack stepless regulation of comb unit height, leading to limited hair cutting length adjustment and a high risk of comb units being lost due to multiple units with different specifications.
Innovation Solution
A beard trimmer with an adjustment assembly that includes a first adjusting connector and an adjustor handle, allowing for the relative movement of comb units with respect to the cutting assembly, enabling stepless regulation of the comb unit height through rotational adjustment of the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple comb units with different specifications are arranged, then the user can select the suitable comb unit, but the comb units are easy to lose and cannot realize stepless regulation
Solution Approach 1:
The patent implements a universal comb unit design where a single comb unit can be adjusted to multiple positions via the adjustment assembly. The comb unit integrates with the adjustment assembly that allows continuous height regulation, eliminating the need for multiple specialized comb units with different specifications. This multi-functional design enables one comb unit to perform the function previously requiring several different comb units.
Solution Approach 2:
The patent merges the comb unit with the adjustment assembly into an integrated structure. The comb unit is combined with the adjustment mechanism such that they function as a unified system, allowing the comb unit to be continuously adjusted in height relative to the cutting assembly. This merging eliminates the need to manage separate comb units and reduces the risk of loss.
2Adaptability or versatility
If multiple comb units with different specifications are arranged, then the user can select the suitable comb unit, but stepless regulation for the limiting length cannot be realized
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the comb unit can be continuously positioned at any height relative to the cutting assembly. The adjustment assembly includes a movable comb unit that can be adjusted along the axial direction of the adjustor handle, enabling dynamic and continuous (stepless) regulation of the limiting length rather than fixed discrete positions.
Solution Approach 2:
The patent changes the parameter of comb unit position from fixed discrete values to continuously variable values. The adjustment assembly allows the comb unit position to be varied continuously along the axial direction, transforming the limiting length parameter from a set of discrete values to a continuous range,从而实现 stepless regulation.
3Ease of operation
If the adjustment assembly allows comb units to move relative to the cutting assembly, then stepless regulation is enabled, but the device complexity increases
Solution Approach 1:
The adjustment assembly is designed to be user-operable without requiring complex tools or procedures. The adjustor handle directly controls the movement of the comb unit through a simple rotational motion that translates to axial movement. This self-service design allows the user to easily adjust the comb unit position without assistance or complex mechanisms.
Solution Approach 2:
The adjustor handle serves as an intermediary mechanism between the user's rotational input and the comb unit's axial movement. The first adjusting connector acts as a mediator that converts the rotational motion of the adjustor handle into linear translation of the comb unit along the axial direction, simplifying the user interaction while achieving the desired adjustment function.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise adjustment of hair cutting length and reduces the risk of comb unit loss by allowing for easy replacement and precise positioning of comb units.
Implementation Method 1
The adjustor handle is spirally connected to the first adjusting connector... When rotating, the adjustor handle drives the first adjusting connector to translate along an axial direction of the adjustor handle

AI summary
The present disclosure provides an adjustment assembly and a beard trimmer. The adjustment assembly includes a guide hole, a first adjusting connector and an adjustor handle, and the adjustor handle is spirally connected to the first adjusting connector. The first adjusting connector includes an extension arm, a connecting structure, which is used to connect with an external structure, is arranged on the extension arm, a guide hole is formed in the guide hole, and the extension arm penetrates through the guide hole. When the guide hole is in a fixed state, the adjustor handle is rotated, and the extension arm moves along the guide hole. After the adjustment assembly is installed on the beard trimmer in the present disclosure, the height of the comb unit may be regulated, and a user can adjust the hair cutting length by accurately regulating the extending length of the comb unit.
