Problem

Conventional blender devices require electric power to achieve high rotational speeds necessary for effective shredding and blending, limiting their use in situations without a power source.

Innovation Solution

A manually-operated blender device that utilizes a rotatable portion to generate high RPMs by rolling along a surface, featuring a gear system and multiple blade subassemblies to efficiently chop, blend, and liquefy food and other materials without electricity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If an electric motor is used to achieve high rotational speeds for effective shredding and blending, then the blending performance is improved, but the device requires a source of electric power which limits portability and usability without power sources

Engineering Contradiction:

Improveblending performanceVSAvoidportability

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent replaces the electric motor system with a manual mechanical system. The user manually rotates the blade assembly through a gear mechanism that converts rotational motion into high-speed blade rotation, eliminating the need for electric power while maintaining blending capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a dynamic gear system that allows the blade assembly to rotate at variable speeds depending on user input. The mechanical advantage provided by the gear train enables the user to achieve high rotational speeds temporarily for effective blending, then return to a stationary state, creating a dynamic operational mode that balances performance and portability.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a manual operation system is used to eliminate electric power requirements, then portability is improved, but achieving sufficiently high rotational speeds for effective shredding becomes difficult

Engineering Contradiction:

ImproveportabilityVSAvoidrotational speed

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The manual operation system is designed for periodic action where the user rotates the blade assembly in short bursts to achieve the necessary rotational speed for shredding, then allows it to coast down. This periodic activation pattern enables effective blending while maintaining portability, as the high-speed operation is intermittent rather than continuous.

Inventive Principle:

Principle #19Periodic action

3Productivity

If multiple blade subassemblies are used to improve blending efficiency, then the blending performance is enhanced, but the device complexity increases

Engineering Contradiction:

Improveblending efficiencyVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the blade system into multiple independent blade subassemblies that can rotate together. Each subassembly contains blades positioned at different angles and locations, allowing them to work in concert to chop and blend materials more effectively than a single blade assembly could achieve.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines multiple blade subassemblies into a single integrated rotating system driven by one manual operation. All blade subassemblies are mounted on the same rotational axis and are driven simultaneously, merging their cutting actions to achieve enhanced blending efficiency while maintaining a unified control mechanism.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A handheld, hand-operated blender may include a container, a lid threadably connected to an upper portion of the container, a bottom portion including a stationary bottom portion threadably connected to a lower portion of the container and a rotatable bottom portion rotatable with respect to the container. The blender may also include a blade assembly including a plurality of blades and a shaft rotatably connected to the rotatable bottom portion and a gear assembly mechanically connected to the blade assembly and the rotatable bottom portion such that rotation of the rotatable bottom portion rotates the blade assembly at a faster revolution per minute than the rotation of the rotatable bottom portion.
