Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Costumed character outfits often limit an entertainer's ability to interact realistically with their surroundings due to constraints on character appendages, such as hands, limiting the ability to grasp or manipulate stage props effectively.

Innovation Solution

Integration of electromagnets and magnetic pieces into character costumes and stage props, controlled by a control interface, allowing for magnetic interactions to facilitate realistic interactions, including the use of electromagnetic locks to engage and disengage with stage props.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional costumed character outfits are used, then the costume provides character appearance and theme, but the entertainer's ability to interact realistically with surroundings is limited

Engineering Contradiction:

Improveability to interact with surroundingsVSAvoidcostume structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces mechanical grasping systems with an electromagnetic system. An electromagnet integrated into the costume can magnetically attract stage props containing magnetic pieces, eliminating the need for physical hand grasping mechanisms while enabling realistic interaction. This substitution resolves the contradiction by providing effective interaction capability without complex mechanical structures in the costume.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic pieces as intermediary elements between the electromagnet in the costume and the stage props. These magnetic pieces act as mediators that enable magnetic attraction and realistic interaction without requiring direct mechanical contact or complex grasping mechanisms, thus improving ease of operation while maintaining simple costume structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If costume appendages are designed to mimic character appearance, then character realism is improved, but the ability to grasp and manipulate stage props is reduced

Engineering Contradiction:

Improvecharacter realismVSAvoidability to grasp props

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces mechanical grasping functionality with an electromagnetic attraction system. The electromagnet can magnetically secure stage props without requiring the costume appendages to have complex mechanical grasping structures, thereby maintaining character realism while enabling versatile prop manipulation through magnetic force.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the interaction parameter from mechanical contact to magnetic attraction. By using electromagnetic force instead of physical grasping, the costume can manipulate stage props effectively while maintaining the appearance and structure needed for character realism, thus resolving the contradiction between reliability and adaptability.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If electromagnets are integrated into the costume, then magnetic interaction with stage props is enabled, but the costume complexity increases

Engineering Contradiction:

Improvemagnetic interaction capabilityVSAvoidcostume structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical grasping and manipulation systems with a simple electromagnet integrated into the costume. This single electromagnetic component provides versatile magnetic interaction capability with stage props, achieving high adaptability while minimizing costume structure complexity compared to mechanical alternatives.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
