Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ice shavers are inefficient in producing fine shavings from larger ice blocks and often result in splashing and contamination issues during the shaving process.
Innovation Solution
The ice shaver incorporates an in-line power control drive system, a thermally isolated modular shave disc, and a 360° magnetic floating splash guard to efficiently shave ice and prevent splashing, featuring a multi-link motion control arm and a double wishbone spring blade holder for improved stability and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing ice shavers are used to shave ice from larger blocks, then ice shaving function is provided, but the production efficiency of fine shavings is low
Solution Approach 1:
The patent employs a dynamic shaving mechanism where the shave head moves reciprocally against the ice block while the blade rotates, creating optimal cutting conditions that produce fine shavings efficiently. The multi-link control arm enables this dynamic motion with mechanical advantage, allowing the blade to maintain consistent contact and produce uniform fine shavings at high speed.
Solution Approach 2:
The patent replaces traditional manual or simple mechanical shaving with an electric motor-driven system featuring a rotating blade and reciprocating motion. This substitution of mechanical systems enables higher productivity while maintaining precise control over shaving fineness through the engineered blade geometry and motion control mechanism.
2Productivity
If ice shaving is performed with existing devices, then ice is shaved, but splashing and contamination issues occur
Solution Approach 1:
The patent introduces a splash guard as an intermediary component between the blade and the surrounding environment. This guard contains the shaving area, preventing ice shards and water from splashing outward and causing contamination. The splash guard acts as a barrier that maintains productivity while eliminating the harmful splashing effect.
Solution Approach 2:
The patent extracts and isolates the shaving operation within a contained space defined by the splash guard and housing. By separating the shaving zone from the external environment, the system prevents contamination while maintaining efficient ice shaving operation.
3Ease of operation
If traditional ice shaver design is used, then basic shaving function is achieved, but thermal isolation is insufficient causing ice melting
Solution Approach 1:
The patent introduces thermal isolation components as intermediaries between the ice block and the external environment. These components include thermal insulation on the housing and thermally isolated mounting for the shave head, which prevent heat transfer from the surroundings to the ice block, thereby maintaining temperature stability and preventing unwanted melting.
Solution Approach 2:
The patent applies thermal isolation specifically at critical locations where heat transfer would most affect the ice block, such as the housing walls and the shave head mounting. This localized application of thermal isolation properties maintains ice temperature stability without requiring complete thermal insulation of the entire device.

AI summary
The present invention provides an ice shaver with a multi-link, self-locking, force-reduction, motion control arm or armature to press an ice block against a blade. The armature has a lever with a forward handle, an intermediate connection to the column, and a rear connection to the frame of the ice shaver. A link is coupled between the rear connection of the lever and the frame of the ice shaver to form a four-bar linkage. The armature has a raised locked configuration in which the lever and the link are oriented substantially co-linear to maintain the column in a raised position. In another aspect, joints between the lever and the column can comprise dampers.
