Solution Overview

Problem

Conventional bobbling apparatuses enable individual bobbling of components, limiting the variety and type of bobblehead dolls that can be produced, and lack a mechanism for synchronized movement of multiple components.

Innovation Solution

An articulating apparatus with joining and connecting modules that allow two or more bobbling components to move synergistically in unison, using mechanisms such as magnets, electromagnets, springs, and rack and pinion sets to connect and coordinate the movement of multiple components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate mechanisms are used for each bobbling component, then each component can bobble independently, but the device complexity increases and the number of bobbling configurations is limited

Engineering Contradiction:

Improvenumber of bobbling configurationsVSAvoidnumber of separate mechanisms

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple independent bobbling mechanisms into a single integrated mechanism. The joining module connects multiple bobbling components (head, arms, legs) through a shared mechanical system, allowing them to bobble simultaneously with a single actuation source, thereby reducing overall device complexity while enabling synchronized multi-component bobbling configurations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The joining module serves multiple functions: it connects different bobbling components, transmits motion from a single actuator to multiple components, and enables various bobbling configurations through different component arrangements. This universal module replaces the need for separate mechanisms for each component, increasing adaptability while controlling complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate bobbling mechanisms are used, then more components can bobble, but the manufacturing cost increases

Engineering Contradiction:

Improvenumber of bobbling componentsVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By merging multiple bobbling mechanisms into one integrated joining module, the patent reduces the total number of parts that need to be manufactured and assembled. The single actuator and shared mechanical structure eliminate redundant components, lowering manufacturing costs while still enabling multiple components to bobble simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The universal joining module can be used across different bobbling configurations and component types, allowing for standardized manufacturing processes. This multi-functional design enables the same module to support various numbers and types of bobbling components, reducing development and tooling costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If a single mechanism controls multiple bobbling components, then device complexity reduces, but the synchronization precision of bobbling movement must be maintained

Engineering Contradiction:

Improvenumber of mechanismsVSAvoidsynchronization of bobbling movement

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent employs conical springs in the joining module, which utilize their curved geometric properties to naturally distribute and synchronize motion transmission. The conical shape provides progressive engagement and smooth motion transfer to multiple components, maintaining synchronization precision while using a single actuator, thereby reducing device complexity without sacrificing movement coordination.

Inventive Principle:

Principle #14Spheroidality (Curvature)
