Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals face difficulties in accessing hard-to-reach areas for shaving due to limited flexibility or physical impairments, and existing solutions fail to securely extend the reach of shaving razors, leading to instability and balance issues.
Innovation Solution
A razor extender with a cradle and extension arm, utilizing an elastomeric lash to securely hold the razor handle, allowing for adjustable capacity to accommodate various handle sizes and shapes, and featuring a design that prevents rocking, ensuring stability and safety during shaving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cradle with fixed dimensions is used to hold the razor handle, then the razor can be securely held, but it cannot accommodate handles of different sizes and shapes
Solution Approach 1:
The cradle's effective holding dimensions are changed by repositioning the lash across different pairs of edges. The lash can be positioned to span different edge pairs, effectively changing the cradle's internal dimensions to match various handle sizes and shapes without modifying the cradle structure itself.
Solution Approach 2:
The system transitions from a static cradle configuration to a dynamic one where the lash position can be adjusted. This allows the cradle to adapt its holding characteristics based on the specific razor handle being used, providing versatility while maintaining a simple fixed structure.
2Stability of the object's composition
If the cradle length is increased to prevent rocking, then stability improves, but the device becomes less adaptable to different handle sizes
Solution Approach 1:
Instead of changing the physical cradle length, the effective stability parameter is changed by adjusting the lash position. Placing the lash across wider-spaced edges increases the effective support span and stability for larger handles, while closer edges provide better fit for smaller handles.
Solution Approach 2:
The cradle edges are segmented into multiple pairs at different spacings. The lash can be positioned across different pairs depending on the handle size, allowing the same cradle structure to provide appropriate stability for various handle dimensions.
3Manufacturing precision
If a secure holding mechanism is used to prevent razor shifting, then shaving accuracy improves, but the device complexity increases
Solution Approach 1:
The lash automatically secures the razor handle in place through its elastic tension and geometric constraint. The system is self-regulating, where the lash tension and edge spacing naturally prevent razor shifting without requiring additional active control mechanisms or complex components.
Solution Approach 2:
The holding security is achieved by changing the geometric parameters of the lash-razor interface. The lash tension, edge spacing, and lash position are adjusted to optimize the securing effect for different handle sizes, providing accurate shaving without complex mechanisms.

AI summary
An extender has a cradle at the distal end of an extension arm. The handle of a razor is placed in the cradle and held in place by a lash that connects across the spaced edges of the cradle. The length of the cradle avoids rocking of the razor handle about an axis transverse to the longitudinal axis of the cradle.
