Flexible Shell Structure for Show Elements Using Segmented Rigid Strips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid shell structures used in show elements, such as animated figures, limit the mechanical capabilities and range of motion due to their fixed size and shape, which conflicts with the aesthetic requirements.
Innovation Solution
A flexible shell structure composed of rigid support strips and coupling members that allow the structure to flex in one direction while resisting flexing in another, enabling improved range of motion without compromising the aesthetic appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rigid shell structure is used to enclose hardware in show elements, then the aesthetic appearance is maintained, but the range of motion and mechanical capabilities are limited
Solution Approach 1:
The shell structure is divided into multiple rigid support strips that are separated by coupling members, allowing each strip to move independently while maintaining overall structural integrity. This segmentation enables the shell to flex and accommodate range of motion while preserving aesthetic appearance through the coordinated movement of individual strips.
Solution Approach 2:
The patent applies flexible coupling members between rigid support strips, creating a hybrid structure that combines rigid aesthetic elements with flexible connecting components. This allows the shell to deform elastically during movement, providing range of motion while maintaining the visual appearance of a solid structure.
2Shape
If a rigid shell structure is used to maintain aesthetic appearance, then the visual quality is improved, but the structure cannot accommodate mechanical stress and movement
Solution Approach 1:
The shell structure transitions from a static rigid form to a dynamic system where rigid support strips are connected by flexible coupling members. This dynamic design allows the structure to adapt its rigidity based on movement requirements, maintaining aesthetic appearance during static display while accommodating mechanical stress during operation through controlled flexing.
3Ease of operation
If the shell structure is made flexible to improve range of motion, then mechanical capability is enhanced, but the aesthetic appearance may be compromised
Solution Approach 1:
The shell structure applies different properties to different locations: rigid support strips maintain aesthetic appearance in visible areas, while flexible coupling members provide mechanical capability in connecting regions. This local differentiation allows the structure to exhibit rigidity where visual quality is paramount and flexibility where mechanical capability is required.
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 flexible shell structure enhances the range of motion of show elements, preventing damage from mechanical stress and supporting heavy coverings like stage costumes while maintaining a realistic appearance.
Implementation Method 1
The at least one coupling member enables the flexible shell structure to flex when a first force is applied to the flexible shell structure in a first direction
Implementation Method 2
enables the flexible shell structure to resist flexing when a second force is applied to the flexible shell structure in a second direction

AI summary
Aspects of the present disclosure are related to a flexible shell structure. The flexible shell structure includes a plurality of rigid support strips that collectively define a three-dimensional shape of at least one part of a character form. The flexible shell structure further includes at least one coupling member configured to couple two or more rigid support strips of the plurality of rigid support strips. The at least one coupling member enables the flexible shell structure to flex when a first force is applied to the flexible shell structure in a first direction, and enables the flexible shell structure to resist flexing when a second force is applied to the flexible shell structure in a second direction.
