Solution Overview

Problem

Conventional shaver handles are cumbersome for travel due to their fixed length, which can be unsuitable for both men and women, and often do not fit within small luggage or toiletry bags, leading to ergonomic issues and space inefficiencies.

Innovation Solution

A shaver handle design featuring a first section and a second section that are translatable along a proximal-distal axis, connected by a sleeve that transitions between extended and collapsed conformations, allowing for adjustable length through snap joints and motion limiters, and potentially incorporating elastic materials for flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the shaver handle is made with a fixed length, then the structure is simple and easy to manufacture, but it occupies excessive space during travel and does not accommodate different hand sizes

Engineering Contradiction:

Improveadaptability to different hand sizes and travel conditionsVSAvoidstructural complexity of the handle

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shaver handle is divided into a first section and a second section that can be translated relative to each other along the proximal-distal axis. The first section includes a plurality of grooves and the second section includes at least one protrusion that forms a snap joint with the grooves, enabling the handle to be segmented into adjustable length portions while maintaining structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shaver handle transitions from a fixed-length static structure to a dynamic adjustable-length structure. The sleeve connects the first and second sections and is configured to transition between extended and collapsed conformations, allowing the handle length to be dynamically adjusted based on user needs and travel conditions.

Inventive Principle:

Principle #15Dynamics

2Volume of moving object

If the shaver handle length is reduced for better storage, then it fits in smaller luggage, but it becomes less ergonomic for users with larger hands

Engineering Contradiction:

Improvestorage volume of the handleVSAvoidergonomic comfort during use

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The handle employs a dynamic length adjustment mechanism where the sleeve transitions between extended and collapsed states. When extended, the handle provides adequate length for ergonomic comfort during shaving. When collapsed, the handle reduces to a compact form factor that fits within small luggage and toiletry bags.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The handle is segmented into movable sections with snap joints that allow the user to adjust the effective length by repositioning the second section relative to the first section. This segmentation enables the handle to provide full length during use for ergonomics, then collapse to a compact configuration for storage.

Inventive Principle:

Principle #1Segmentation

3Volume of moving object

If the handle is made collapsible for compact storage, then it fits in small spaces, but the mechanism becomes more complex

Engineering Contradiction:

Improvestorage volume when collapsedVSAvoidcomplexity of the collapse mechanism

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The handle is divided into a first section and a second section connected by a sleeve. The first section includes grooves and the second section includes a protrusion that forms a snap joint, creating a segmented structure that enables collapse without requiring complex mechanical mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The snap joint mechanism between the first and second sections provides self-aligning and self-locking functionality. The protrusion on the second section automatically engages with the grooves on the first section during assembly and disassembly, eliminating the need for additional fasteners, springs, or complex actuation mechanisms.

Inventive Principle:

Principle #25Self-service

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 adjustable length feature enhances user ergonomics by accommodating different hand sizes and allows for more efficient storage by reducing the handle's overall length when not in use, fitting within smaller spaces.

Implementation Method 1

The sleeve may comprise an elastic material, more specifically an elastomer and in particular an elastomeric silicone.
