Solution Overview

Problem

Traditional children's toys with motorized components require specific motor and battery configurations for each toy, leading to increased manufacturing and consumer costs due to the need for unique power units, despite often having similar internal components.

Innovation Solution

A system of toys featuring a removable and interchangeable power unit that includes a motor and battery, along with a multi-component drive arrangement capable of powering various toy components, allowing compatibility with different toy bodies and reducing complexity and cost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a specific motor and battery configuration is installed in each toy, then the toy can be motorized with reliable power, but the manufacturing cost and consumer cost increase due to requiring unique power units for each toy

Engineering Contradiction:
Improvemotorized function reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies universality by designing a standard power unit with uniform electrical connections and mounting features that can be used across multiple different toy types. The power unit includes standardized battery compartments, motor mounting interfaces, and electrical contacts that accommodate various toy bodies (cars, trucks, robots) without requiring toy-specific customization, thereby reducing manufacturing costs while maintaining reliable motorized function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the toy system into two independent components: a reusable power unit module and a toy body. The power unit is designed as a self-contained module with battery, motor, and control circuitry that can be manufactured separately and then installed into different toy bodies. This segmentation allows the power unit to be produced in volume for multiple toy variants, reducing per-unit manufacturing cost while ensuring consistent reliable operation across all toys.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a specific motor and battery configuration is installed in each toy, then the toy can operate with dedicated power, but the consumer must purchase multiple toys even when only the outer shell differs

Engineering Contradiction:
Improvetoy configuration specificityVSAvoidconsumer cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent enables consumers to purchase a single power unit that can be transferred and used across multiple different toy bodies. The standardized power unit design with universal electrical and mechanical interfaces allows one power unit to serve multiple toy functions (car, truck, robot), eliminating the need for consumers to buy separate power units for each toy variant and reducing overall consumer expenditure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces dynamic reconfigurability where the power unit can be dynamically transferred between different toy bodies based on user needs. The power unit includes removable mounting features and flexible electrical connections that allow it to be installed in various toy configurations, enabling consumers to adapt their toy collection by swapping power units rather than purchasing entirely new toys.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If a removable and interchangeable power unit is used, then manufacturing cost and consumer cost are reduced, but the power unit must be compatible with multiple different toy configurations

Engineering Contradiction:
Improvemanufacturing costVSAvoidpower unit compatibility design
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies local quality by providing different adapter interfaces or mounting configurations only at the local contact points where the power unit connects to the toy body, while the core power unit remains standardized. This allows the power unit to accommodate multiple toy types through simple interface variations (such as different gear train configurations or wheel drive arrangements) without requiring complete redesign of the entire power unit, thus managing compatibility complexity efficiently.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses intermediary adapter components that facilitate compatibility between the standardized power unit and various toy body types. These adapters act as mediators, providing the necessary mechanical and electrical interface variations to match different toy configurations while maintaining the core power unit design, thereby reducing the complexity of designing completely custom power units for each toy.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Stability of the object's composition

If traditional encapsulated motor and battery are used, then the power source is fixed for that toy, but the complexity and cost increase for each unique toy design

Engineering Contradiction:
Improvepower source configurationVSAvoidoverall system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent extracts the motor and battery from the traditional encapsulated toy design and consolidates them into a separate, removable power unit module. This extracted power unit can then be used across multiple different toy bodies, reducing the overall system complexity by eliminating redundant motor and battery installations in each toy while maintaining stable and reliable power source configuration through the standardized module.

Inventive Principle:
Principle #2Taking out (Extraction)
