Block Ice Shaver with Flexible Blade for Consistent Texture

Solution Overview

Problem

Existing ice shaving machines face limitations such as cumbersome ice block change procedures, frozen and impacted blades, inconsistent shaved ice textures, and reduced efficiency as the ice warms, making them unsuitable for both home and large-volume use.

Innovation Solution

An ice shaving machine with a flexible blade assembly and ice block feeder system that allows for consistent shaving of block ice, featuring a blade holder with tensioned blades and a drive shaft mechanism to maintain efficient ice shaving even as the ice warms, along with a flavor dispensing system for convenient flavoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a block of ice is shaved using a traditional blade mechanism, then ice shavings are produced, but the blade becomes frozen and impacted reducing shaving quality

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The blade is designed to be flexible rather than rigid, allowing it to dynamically adapt to the ice block surface and maintain contact during rotation. This flexibility prevents the blade from becoming frozen and impacted, maintaining consistent shaving performance throughout operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The blade's flexibility parameter is specifically engineered to allow slight deflection under load, enabling it to conform to the ice surface geometry and maintain effective cutting contact. This parameter change from rigid to flexible resolves the blade impact and freezing problem.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the ice block warms and changes texture, then the ice becomes softer and harder to shave, but traditional machines cannot adapt to this changing consistency

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The flexible blade dynamically adjusts its shape and contact pressure in response to changing ice consistency. As the ice warms and softens, the blade automatically adapts its flexibility to maintain optimal cutting engagement, preserving shaving efficiency throughout the ice block's thermal evolution.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The blade system self-adjusts to changing ice conditions without external control. The flexible blade automatically conforms to the ice surface and adapts to texture changes through its inherent mechanical properties, eliminating the need for manual adjustment mechanisms.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If a large block of ice is used to operate at higher volume, then more ice can be shaved, but the machine operates more slowly and requires significant maintenance

Engineering Contradiction:
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The blade is designed as a segmented flexible structure rather than a single rigid piece. This segmentation allows different portions of the blade to independently adapt to the ice surface, improving cutting efficiency and enabling faster processing of large ice blocks without compromising blade durability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The blade's physical parameters, particularly its flexibility and thickness distribution, are optimized to enable efficient cutting of large ice blocks. This parameter optimization allows the blade to maintain high cutting speeds even when processing substantial ice volumes.

Inventive Principle:
Principle #35Parameter changes

4Strength

If the blade is made rigid to maintain structural integrity, then the blade holder is simple, but the blade cannot adapt to ice surface variations and becomes impacted

Engineering Contradiction:
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The blade is constructed as a flexible thin structure that maintains sufficient structural integrity through its material properties and geometry while allowing necessary deflection. This flexible blade design enables adaptation to ice surface variations without compromising strength, resolving the contradiction between rigidity and adaptability.

Inventive Principle:
Principle #30Flexible shells and thin films
