Modular Rotating Image Display for Portable Barrel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotating image displays are bulky and lack portability due to fixed installations, requiring motors, power supplies, and adhesives, making them difficult to assemble, disassemble, and store, especially for larger sizes like postcards.
Innovation Solution
A modular rotating image display apparatus with a lens sheet, holding units, closing units, a rotating shaft, and a support unit that allows for easy assembly and disassembly, featuring a detachable design for compact storage and use, including a driving unit for rotational force and a bearing component for rotation support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rotating image displays use motors, power supplies, and adhesives for fixed installation, then rotational driving capability is achieved, but device complexity and portability are worsened
Solution Approach 1:
The display device is divided into multiple independent modules: image display sheets, holding units, closing units, rotating shaft, bearing component, and support unit. Each module can be independently manufactured, assembled, and disassembled, eliminating the need for complex fixed installations while maintaining rotational functionality.
Solution Approach 2:
The patent transitions from static fixed installations to dynamic modular assembly. The holding units can detachably hold image display sheets, the closing units can close openings, and the rotating shaft can rotate the barrel unit, allowing the system to adapt between assembled and disassembled states for different operational needs.
2Stability of the object's composition
If conventional displays are fixed with screws or adhesives, then structural stability is improved, but ease of assembly and disassembly is worsened
Solution Approach 1:
The structure is segmented into modular components connected through standardized interfaces. The holding units, closing units, and support unit feature detachable connections that provide sufficient structural stability when assembled while allowing easy disassembly without screws or adhesives.
Solution Approach 2:
The patent uses gravity and simple mechanical interlocking of the modular components to achieve adequate structural stability for the intended application, rather than over-engineering with excessive fastening mechanisms. This partial action approach provides sufficient stability while maintaining ease of assembly and disassembly.
3Reliability
If conventional displays are assembled permanently, then reliability is improved, but portability and storage efficiency are worsened
Solution Approach 1:
The system dynamically transitions between assembled operational state and disassembled storage state. The modular components maintain reliable connections during operation through proper mechanical interfacing, yet can be easily separated for portability and storage, providing adaptability between different usage scenarios.
Solution Approach 2:
The modular components can be temporarily 'discarded' or separated from the assembly for storage and transport, then recovered and reassembled for use. This allows the system to achieve both reliability during operation and portability during storage without compromising either function.

AI summary
The apparatus includes holding components 12a, 12b, 12c, 12d as a holding unit that holds image display sheets 10a, 10b, 10c, 10d detachably in a cylinder-like fashion and thereby configures a barrel unit 11; a pair of closing units 13a, 13b that detachably close openings at both ends of the barrel unit 11; a rotating shaft that removably extends through the inside of the barrel unit 11 from one closing unit 13b to the other closing unit 13a; a support unit 17 that imparts a rotational force to the rotating shaft and includes a driving unit 18 configured to stand upright and to be tilted; and a bearing component 16 that rotatably supports an end of the rotating shaft to enable rotation of the main body of the barrel unit 11.
