Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shaving razor stands do not effectively maintain the safety razor in an upright orientation, allowing water to drain and providing stability during storage, and often lack features for secure handling on smooth surfaces.
Innovation Solution
A shaving razor stand with a U-shaped cavity and elastomeric material for secure handling, a low center of gravity for stability, and gripping elements to prevent slipping, along with optional magnetic retention and water drainage features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional shaving razor stands are used, then the stand structure is simple, but the razor cannot be held securely in an upright orientation and the stand slips on smooth surfaces
Solution Approach 1:
The stand is divided into distinct functional components: a base with gripping elements for surface stability, a body with a U-shaped cavity for razor reception, and elastomeric material for secure handling. This segmentation allows each component to address specific stability issues independently, achieving reliable upright holding without excessive overall complexity.
Solution Approach 2:
The cavity is designed with a non-circular, U-shaped edge that provides asymmetric geometry tailored to the typical shape of safety razor handles. This asymmetric design creates a snug fit that prevents the razor from falling over, improving holding reliability while maintaining a relatively simple structural form.
2Stability of the object's composition
If the stand uses a larger base area for stability, then the center of gravity is lower and stability improves, but the space occupied on the surface increases
Solution Approach 1:
The stand employs a low center of gravity design where the base is positioned to counterbalance the weight of the upright razor. By concentrating mass in the base and positioning it to create a low center of gravity, the stand achieves stability with minimal footprint, as the gravitational force acts through a point well within the small base area.
Solution Approach 2:
The stand optimizes the distribution of mass and geometry parameters to achieve stability. The base area is kept minimal while the height and internal cavity dimensions are adjusted so that the combined center of gravity of the stand and razor remains low and within the base footprint, achieving stability without increasing surface area.
3Ease of operation
If elastomeric material is added to the cavity for secure handling, then the razor grip improves, but the manufacturing complexity increases
Solution Approach 1:
The stand combines rigid structural material (such as plastic or metal) with elastomeric material in the cavity region. This composite construction provides the dual benefits of structural integrity from the rigid material and secure, comfortable handling from the elastomeric material that conforms to the razor, while the integration can be achieved through conventional manufacturing techniques.
Solution Approach 2:
The elastomeric material is applied locally only in the cavity region where razor contact occurs, rather than throughout the entire stand. This localized application provides enhanced handling ease exactly where needed while minimizing the impact on manufacturing complexity and material costs.
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 stand securely holds the razor upright, allows water to drain, and remains stable on surfaces, ensuring easy handling and minimal space usage while preventing slipping.
Implementation Method 1
A portion of the cavity may be configured with an elastomeric material. The elastomeric material in the cavity may be configured to interact with a portion of a handle of a safety shaving razor.
Implementation Method 2
The stand may be configured to have a low center of gravity. The cavity may be configured so that the center of gravity of a shaving razor positioned in the stand will be positioned substantially within the footprint of the base.
