Grooming Accessory Locking Lever for Stable Handle Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grooming devices face challenges in reaching hard-to-reach body areas due to limited visibility and reach, leading to impaired controllability and unsatisfactory grooming results, often causing discomfort and skin irritations.
Innovation Solution
An accessory component with a locking unit featuring a rocking lever mechanism that ensures reliable and stable coupling and decoupling with the grooming device, allowing for easy operation and secure attachment without design changes, and includes a handle extension to increase operational range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a handle extension is added to reach hard-to-reach body areas, then the operational range is improved, but the device stability and controllability deteriorate
Solution Approach 1:
The device is divided into a main body and a separate handle extension that can be attached or detached. The handle extension includes its own locking mechanism with rocking lever and detent nose that independently secures to the main body, allowing the extension to be added for reachability while maintaining stability when attached through the locking mechanism.
2Reliability
If a locking mechanism is added to prevent accidental detachment, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to automatically engage when the handle extension is inserted into the main body. The rocking lever is biased by a spring to move the detent nose into the locking position without requiring user action, and the mechanism self-latches to maintain the locked state without continuous power or intervention.
Solution Approach 2:
The locking mechanism replaces complex electronic locking systems with a simple mechanical spring-loaded rocking lever and detent nose arrangement. This mechanical approach provides reliable locking through pure mechanical engagement of the detent nose with the locking surface, avoiding the need for motors, sensors, or electronic controls.
3Ease of operation
If the rocking lever is designed to be pivotable for easy release, then the ease of operation is improved, but the locking stability deteriorates
Solution Approach 1:
The rocking lever is designed to be stationary and stable in the locked position, providing firm engagement. To release, the user applies force to pivot the rocking lever against the spring bias, which moves the detent nose out of the locking position. Once released, the spring automatically returns the lever to its stable locked position, providing both ease of release and locking stability.
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
Enhances user comfort and grooming accuracy by providing a secure, easy-to-use attachment that prevents accidental detachment, improving controllability and reducing skin irritations, especially in hard-to-reach areas.
Implementation Method 1
a rocking lever (62) having an engagement portion (84) and a release portion (86), wherein a detent nose (88) is formed in the engagement portion (84), wherein the rocking lever (62) is pivotable about a hinge axis (90) between an engagement position and a release position
Implementation Method 2
the rocking lever (62) being movable into the release position by overcoming a biasing force that urges the rocking lever (62) into the engagement position
