Solution Overview

Problem

Climbers and mountaineers face the challenge of carrying excessive weight and incurring high costs by needing to carry multiple tools like snow flukes, snow pickets, and shovels for different climbing and rescue conditions, which can be cumbersome and costly.

Innovation Solution

A multi-use snow tool that combines a snow fluke and a snow picket, allowing them to function together as a shovel or independently as climbing anchors, reducing the need for multiple tools by integrating a snow fluke with a blade body and a snow picket with an elongate shaft, using a lip assembly to detachably couple them, and incorporating a rigging cable for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If climbers carry multiple tools (snow fluke, snow picket, snow shovel) for different conditions, then the reliability and versatility of equipment is improved, but the weight and cost of equipment increases

Engineering Contradiction:

Improveequipment versatilityVSAvoidequipment weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent combines a snow fluke and snow picket into a single integrated tool assembly. The snow fluke blade is coupled with a snow picket shaft and handle, allowing climbers to have both anchoring functions (snow fluke and snow picket) and shoveling capability in one unified device, thereby reducing the number of separate tools needed and the associated weight.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated tool assembly performs multiple functions: the snow fluke portion provides anchoring capability, the snow picket portion provides anchoring capability, and together they form a functional snow shovel for digging and rescue operations. This multi-functional design eliminates the need for climbers to carry separate snow flukes, snow pickets, and shovels.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If climbers carry multiple tools (snow fluke, snow picket, snow shovel) for different conditions, then the reliability and versatility of equipment is improved, but the cost of equipment increases

Engineering Contradiction:

Improveequipment versatilityVSAvoidequipment cost

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Principle #6Universality (Multi-functionality)

3Weight of moving object

If climbers reduce the number of tools carried, then the weight and cost of equipment is reduced, but the reliability and versatility of equipment deteriorates

Engineering Contradiction:

Improveequipment weightVSAvoidequipment reliability

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The tool assembly features a detachable coupling mechanism that allows the snow fluke and snow picket components to be separated or combined based on operational needs. This dynamic configuration enables the tool to adapt between different functions (anchoring vs. shoveling) while maintaining reliability for each specific task.

Inventive Principle:

Principle #15Dynamics

4Weight of moving object

If climbers reduce the number of tools carried, then the weight and cost of equipment is reduced, but the adaptability to different conditions deteriorates

Engineering Contradiction:

Improveequipment weightVSAvoidequipment versatility

Core Design Contradiction:

Weight of moving objectVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The tool is divided into separable components (snow fluke blade, snow picket shaft, handle) that can be independently used or combined. The detachable coupling allows climbers to configure the tool for specific conditions - using only the snow fluke for anchoring, only the snow picket for anchoring, or both together for shoveling operations.

Inventive Principle:

Principle #1Segmentation

AI summary

A multi-use snow tool is described, which includes a snow fluke and a snow picket that may be combined to function as a snow shovel, or may be used independent of each other as climbing anchors. As one example, the multi-use snow tool includes a snow fluke including a blade body having a base end and a nose end opposite the base end; a snow picket having an elongate shaft including at least a first flange; and a lip assembly located at the base end of the blade body and cooperating with the blade body to define at least a first channel that is adapted to mate with the first flange to detachably couple the snow picket to the snow fluke.
