Solution Overview

Problem

Conventional inflatable dolls lack dynamic movement, making them unattractive to passersby as they remain static and fail to engage visitors effectively.

Innovation Solution

An inflatable doll design featuring a body with a first air inlet and expandable members connected to an air blower assembly, where the air blower assembly includes a first air blower to inflate the body and second air blowers to deflate the expandable members, allowing for controlled movement of different portions of the doll, creating dynamic actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional inflatable dolls are made static to maintain structural simplicity, then manufacturing cost and device complexity are reduced, but they become unattractive to passersby due to lack of dynamic movement

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoiddynamic movement capability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The inflatable doll incorporates multiple expandable members (first, second, and third expandable members) that can be independently inflated and deflated to create various dynamic movements including walking, dancing, and waving motions. This transforms the static structure into a dynamic system capable of multiple movement patterns.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The doll's body is divided into multiple independent expandable members (first expandable member in the body, second expandable member in the arm, third expandable member in the leg) that can be controlled separately. This segmentation allows different body parts to move independently, creating complex dynamic movements while maintaining relatively simple individual component structures.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple air blowers are added to create dynamic movements, then the doll becomes more attractive and engaging, but the device complexity and energy consumption increase

Engineering Contradiction:

Improvedynamic movement capabilityVSAvoidair blower assembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single air blower assembly is designed to perform multiple functions by controlling different expandable members. The air blower can inflate the first expandable member for body support, the second expandable member for arm movement, and the third expandable member for leg movement, making one device serve multiple purposes and reducing the need for separate actuators for each body part.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The air blower operates in periodic cycles, alternating between inflating and deflating different expandable members to create rhythmic movements. The system uses intermittent operation where the air blower is activated only when movement is needed, rather than continuous operation, reducing overall system complexity and energy consumption.

Inventive Principle:

Principle #19Periodic action

3Adaptability or versatility

If continuous operation is used to maintain dynamic movements, then visitor engagement is maximized, but energy consumption increases

Engineering Contradiction:

Improvevisitor engagement capabilityVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The inflatable doll employs periodic action by operating the air blower in intermittent cycles rather than continuously. The air blower is activated only when dynamic movement is needed to maintain visitor engagement, and remains inactive during periods when static display is sufficient, thereby significantly reducing energy consumption while preserving the ability to engage visitors when needed.

Inventive Principle:

Principle #19Periodic action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The inflatable doll can perform attractive dynamic movements such as moving up and down or side to side, maintaining visitor engagement by incorporating flexible materials and intermittent air blower actuation, enhancing its appeal compared to static counterparts.
