Transformable Toy Roof Unit With Extendable Legs
Solution Overview
Problem
Existing transformable toys lack the ability to create a small-scale attic room in their attic space, limiting playfulness and form variation.
Innovation Solution
A transformable toy design featuring a roof unit with extendable and retractable leg portions that allow transformation between a two-story and three-story form, where the leg portions protrude to create a smaller attic room, enabling a simple configuration change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the roof unit is fixed without extendable leg portions, then the structure is simple and stable, but the ability to create a small-scale attic room is lost
Solution Approach 1:
The roof unit incorporates extendable and retractable leg portions that can dynamically change position between extended and retracted states. When extended, these leg portions create the attic room space; when retracted, the structure returns to its original simple form. This dynamic mechanism allows the same structure to serve multiple functions without permanently increasing complexity.
Solution Approach 2:
The leg portions are designed to be nested within the roof unit when retracted, similar to a nested doll structure. This allows the extending mechanism to be stored compactly within the existing structure, minimizing the increase in device complexity while maintaining the ability to create additional space when needed.
2Adaptability or versatility
If the leg portions are made extendable to create attic room, then playfulness is enhanced, but the structural complexity increases
Solution Approach 1:
The roof unit is segmented into multiple independent components including the main roof structure and separate extendable leg portions. Each leg portion can be independently controlled to extend or retract, allowing flexible creation of attic room configuration without requiring a completely complex reconfigurable structure. This segmentation simplifies the control mechanism while achieving the desired flexibility.
3Volume of moving object
If a small-scale attic room is created with extendable leg portions, then play space is increased, but the device complexity increases
Solution Approach 1:
The leg portions are designed with self-extending and self-retracting capabilities through simple mechanical mechanisms that utilize the structure's own properties. The extension and retraction actions are achieved through straightforward mechanical means rather than complex motorized systems, allowing the structure to serve itself in creating and eliminating the attic room space without requiring sophisticated control systems.

AI summary
A transformable toy includes: a floor portion and a ceiling portion which define a first room therebetween; and a roof unit. The roof unit includes at least one leg portion extendable to downwardly protrude from the roof unit and retractable inside the roof unit. The transformable toy is transformable between a first form and a second form, the first form in which the roof unit is disposed on the ceiling portion in a state in which the at least one leg portion is retracted inside the roof unit, the second form in which the roof unit is disposed on the ceiling portion in a state in which the at least one leg portion extends to protrude downward from the roof unit to define a second room between the ceiling portion and the roof unit, the second room having a height dimension smaller than that of the first room.
