Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shavers face challenges in conveniently changing and locking shaver heads, adapting to body contours, and providing adequate access to hard-to-reach areas like the back, particularly requiring improved mechanisms for secure attachment and adjustable handles.
Innovation Solution
A shaver system with a locking mechanism featuring a recess and L-shaped grooves for secure attachment, an adjustable shaver head with rotating components for adapting to body contours, and a pivoting handle assembly with a joint system allowing adjustable angles and length for enhanced access to the back.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to secure the shaver head to the handle, then the reliability of attachment is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is divided into separate functional elements: L-shaped grooves in the shaver head, corresponding bumps on the mounting base, and a locking projection. This segmentation allows each component to perform its specific function while maintaining overall simplicity of the attachment system.
Solution Approach 2:
The locking mechanism is designed to automatically engage when the shaver head is attached to the handle base. The L-shaped grooves and bumps self-align and lock together without requiring additional manual operation, providing reliable attachment while minimizing user interaction and mechanism complexity.
2Adaptability or versatility
If the shaver head is made adjustable to follow body contours, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The shaver head is designed with dynamic adjustment capabilities, allowing it to move and adapt to different body contours during use. The connection shaft and positioning racks enable the head to be adjusted to various angles and positions, providing contour adaptability while maintaining a relatively simple mechanical structure.
3Ease of operation
If the handle is made adjustable to reach all areas of the back, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The handle is divided into multiple segments or portions that can be adjusted relative to each other through the joint assembly. This segmentation allows the handle to be configured in different positions and angles, enabling users to reach all areas of the back while keeping each individual joint mechanism relatively simple.
Solution Approach 2:
The joint assembly incorporates dynamic adjustment capabilities, allowing the handle portions to be moved and positioned as needed. The teeth and blocks provide controlled movement and locking at desired positions, enhancing accessibility while maintaining operational simplicity.
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
Enables convenient and secure attachment of shaver heads, improved adaptability to body contours, and enhanced access to all areas of the back, ensuring effective shaving with reduced torque and improved user convenience.
Implementation Method 1
a plurality of springs positioned adjacent the positioning racks, and each spring is aligned with a corresponding baffle so as to be biased against the corresponding baffle for providing a restoring force to the circumferential rotation of the connection shaft
Implementation Method 2
The handle base has a mounting base that includes a locking projection that is fitted inside the recess of the shaver head when the shaver head is connected to the handle base
Implementation Method 3
a circular groove having at least two spaced-apart bumps provided in a wall of the circular groove, with each of the bumps being fitted inside a corresponding L-shaped groove when the shaver head is connected to the handle base
Implementation Method 4
The joint assembly has housing that includes a first joint housing connected to the first handle portion and a second joint housing connected to the second handle portion, the first and second joint housings pivotable with respect to each other
Implementation Method 5
A first circle of inner teeth are arranged inside the first joint housing. Two blocks are retained inside the first joint housing, each block having one group of raised teeth that is adapted to be meshed inside certain teeth of the first circle of inner teeth

AI summary
A shaver includes an improved locking mechanism for securing a shaving head to the shaver while allowing for simple and convenient removal thereof. The shaver further includes an adjustable shaver head that effectively follows the contours of the face or body. The shaver can be extended to use with a backshaver that has a first handle portion connected to a second handle portion by a joint assembly that allows the handle portions to be adjusted to varying angles and locked at a desired angle.
