Solution Overview

Problem

Conventional ice shaving machines experience vibration and uneven force distribution when the ice block deviates from the central position, leading to reduced blade lifetime and sanitation issues due to non-detachable components.

Innovation Solution

An ice shaving machine design featuring a detachable shaving frame with a limit plate and locking grooves, allowing easy assembly, disassembly, and cleaning, along with the ability to be mounted on various surfaces for versatile use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the shaving frame is fixed and non-detachable, then the structure is simple and stable, but it is difficult to clean and causes sanitation problems

Engineering Contradiction:
Improvestructure simplicityVSAvoidcleaning convenience
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The shaving frame is divided into detachable components including the frame body, blade assembly, and cover, which can be separated for easy cleaning and maintenance while maintaining overall structural simplicity when assembled

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the ice block deviates from the central position, then the machine can still process non-central ice blocks, but vibration increases and blade lifetime decreases

Engineering Contradiction:
Improveice block position toleranceVSAvoidblade lifetime
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The rotation disk is designed to rotate dynamically during operation, which helps distribute the cutting forces more evenly across the blade even when the ice block is not centrally positioned, reducing vibration and extending blade life

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the shaving frame is detachable with locking grooves, then cleaning convenience is improved, but device complexity increases

Engineering Contradiction:
Improvecleaning convenienceVSAvoidassembly structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The shaving frame is segmented into detachable parts with simple locking grooves and connecting lugs that enable easy assembly and disassembly without requiring complex mechanisms or tools

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of designing a complex disassembly mechanism, the patent uses a simple reverse approach where the shaving frame can be easily detached by reversing the simple locking connection, minimizing structural complexity while maximizing ease of cleaning

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

An ice shaving machine includes a drive unit, a limit plate secured on the drive unit, and a shaving frame detachably combined with the limit plate. The drive unit includes a rotation disk. The limit plate has a through hole and a plurality of locking grooves. The shaving frame has a receiving chamber and a shaving blade. The shaving frame has a connecting lug detachably locked onto the limit plate. The connecting lug has a passage connected to the receiving chamber and has a plurality of locking pieces that are detachably locked in the locking grooves of the limit plate. Thus, the shaving frame can be rotated to remove from the limit plate so that the shaving frame is detached and cleaned easily and conveniently.
