Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Mountaineers face the risk of frostbite and reduced grip strength due to the cold temperature of ice axes, which are typically made of metal and act as heat sinks, and the challenge of locating the ice axe in visually compromised conditions.

Innovation Solution

An ice axe cover with a thermally insulative material, such as neoprene, that covers the head and shaft of the ice axe, featuring hook-and-loop fasteners for easy attachment, and includes reflective and grip-enhancing components to improve visibility and grip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the ice axe is made of metal to ensure durability and functionality, then the strength and reliability are improved, but the thermal conductivity increases causing heat loss from the user's hand

Engineering Contradiction:

Improveice axe strengthVSAvoidheat loss from hand

Core Design Contradiction:

StrengthVSLoss of energy

Solution Approach 1:

The patent introduces a cover made of thermally insulative material as an intermediary layer between the metal ice axe and the user's hand. This cover acts as a thermal barrier that blocks heat transfer from the hand to the cold metal axe, while still allowing the user to grip and operate the axe effectively. The cover can be removed or adjusted when full functionality is needed.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of energy

If the ice axe head is covered to provide thermal insulation, then the heat loss is reduced, but the grip strength and control are worsened due to reduced friction

Engineering Contradiction:

Improveheat loss from handVSAvoidgrip strength

Core Design Contradiction:

Loss of energyVSEase of operation

Solution Approach 1:

The patent employs a flexible cover that conforms to the shape of the ice axe head and shaft. This flexible shell provides thermal insulation while maintaining the ergonomic contours of the original grip surfaces. The material is chosen to balance insulation properties with sufficient surface friction for effective gripping.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The cover is designed to be dynamically adjustable - it can be installed or removed based on environmental conditions and usage requirements. In extremely cold conditions, the cover provides insulation; when precision control or full grip friction is needed, the cover can be removed or partially displaced.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the ice axe is used in frigid environments below -30 Celsius, then the mountaineering capability is improved, but the risk of frostbite to the user's hand increases

Engineering Contradiction:

Improvemountaineering capabilityVSAvoidfrostbite risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the principle of beforehand cushioning by providing a thermal protective cover before the user's hand is exposed to the extreme cold of the metal ice axe. This preventive measure cushions against the harmful thermal effect before frostbite can occur, allowing users to operate the ice axe safely in temperatures below -30 Celsius without direct thermal contact with the cold metal surfaces.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Loss of energy

If the ice axe cover is made to fully cover the head and shaft for maximum insulation, then the thermal protection is improved, but the accessibility to functional parts is worsened

Engineering Contradiction:

Improveheat loss from handVSAvoidaccessibility to functional parts

Core Design Contradiction:

Loss of energyVSEase of operation

Solution Approach 1:

The patent divides the ice axe into functional segments - the head portion and the shaft portion - and provides separate cover components for each segment. This segmentation allows the user to cover only the portions that require thermal insulation while leaving exposed the functional parts that need to be accessed or operated, such as the pick teeth or adze cutting edge.

Inventive Principle:

Principle #1Segmentation

AI summary

An ice axe cover comprises a head section configured to cover at least a portion of a head of an ice axe. The head section comprises an adze slot for receiving an adze of the ice axe and a pick sleeve for receiving a pick of the ice axe. In some embodiments, at least a cutting edge of the adze is exposed outside the adze slot, and at least a tip of the pick is exposed outside the pick sleeve. The ice axe cover can also comprise a shaft section that covers at least some of a shaft of the ice axe. The shaft section can extend from a shaft junction between the pick sleeve and adze slot of the head section. The ice axe cover can comprise a thermally insulative material, such as neoprene, a grip component, and a reflective component.
