Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building large snowmen is difficult due to the weight and unevenness of snowballs, requiring significant effort and often resulting in imperfect shapes, with issues including rolling heavy boulders, achieving symmetry, and maintaining structure against melting and wind.
Innovation Solution
The creation of lightweight snow spheres with an adhesive surface, allowing for easier handling and assembly, which can be stacked to form symmetrical snow figures with improved stability and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional snowballs are used to build snowmen, then the snowmen can be made with simple materials, but the snowballs become too heavy to handle and roll when made large
Solution Approach 1:
The invention divides the snowball into two segments: a lightweight inner core (foam or inflatable structure) and an outer snow shell. This segmentation allows the snowball to maintain a large size for visual impact while keeping the overall weight manageable, resolving the contradiction between size/weight and ease of handling
Solution Approach 2:
The invention uses a lightweight inner core (foam or inflatable structure) that counterbalances the weight of the outer snow shell. This anti-weight principle allows the snowball to be large enough to look impressive but light enough to roll and position easily, directly addressing the weight vs. handling ease contradiction
2Volume of moving object
If large snowballs are rolled to make big snowmen, then the snowmen can be made bigger, but the snowballs become uneven and difficult to balance
Solution Approach 1:
The invention applies preliminary action by pre-forming the inner core into a perfectly spherical shape before adding the snow shell. This pre-established geometric foundation ensures that the final snowball is symmetric and uniform, eliminating the unevenness problem that occurs when rolling large snowballs from scratch
Solution Approach 2:
The invention uses the inner core as a template or copy that defines the perfect spherical shape. The snow shell is then applied to replicate this ideal geometry, ensuring symmetry and uniformity without the need for manual shaping, thus resolving the precision problem
3Volume of moving object
If heavy snow boulders are used for large snowmen, then the snowmen can be made larger, but it requires significant physical effort to lift and position them
Solution Approach 1:
The lightweight inner core (foam or inflatable) acts as a counterweight that offsets the mass of the outer snow shell. This allows the snowman to achieve large dimensions while requiring minimal force to lift and position components, directly resolving the contradiction between size and force requirement
Solution Approach 2:
By segmenting the snowball into a lightweight core and a thinner snow shell, the invention reduces the overall mass that must be lifted and positioned. This segmentation allows large snowmen to be constructed with minimal physical effort while maintaining visual impact
4Volume of moving object
If more snow is used to make larger snowmen, then the snowmen can be bigger and more detailed, but there is often not enough snow available
Solution Approach 1:
The invention uses composite materials by combining a non-snow inner core (foam or inflatable structure) with an outer snow shell. This composite approach allows the creation of large snowmen using minimal actual snow, resolving the contradiction between size and snow quantity requirement
Solution Approach 2:
The invention changes the material parameter of the snowball's composition, replacing a significant portion of snow with lightweight alternative materials. This parameter change allows large snowmen to be constructed with reduced snow consumption while maintaining structural integrity and visual appearance

Data Source
AI summary
A ball is provided forming an inside structure of the snow person, the ball having an inner and outer surface. The ball is a unitary work piece that is free and unconnected to other work pieces. An adhesion surface is disposed on the outer surface of the ball, the adhesion surface provided with nodules that extend away from the surface of the ball to adhere snow while the ball is rolled. Light units are integrated into the surface of the ball and having light emitting portions that extend away from the surface of the ball. A light output of the light units is selected to transmit light through a layer of snow. Connections between the light units situated within the ball connect the light units together.
