Solution Overview

Problem

Conventional self-supporting display devices have complex construction and assembly details, leading to high costs and require internal complementary structural parts for automatic assembly, making them difficult to assemble and disassemble.

Innovation Solution

A simplified assembly system using foldable walls with wrinkle configurations and an elastic band, where the assembly parts with aligned grooves and separate walls acting as tweezers allow for automatic opening and closing of the display by tensioning the elastic band, enabling easy assembly and disassembly without complex internal structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If conventional self-supporting display devices use internal complementary structural parts for automatic assembly, then automatic assembly function is achieved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveautomatic assemblyVSAvoidinternal complementary structure
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent removes the complex internal complementary structural parts from the display device and replaces them with external assembly parts that have foldable walls. These assembly parts interact with the display body through grooves and wrinkles on the external surface, eliminating the need for hidden internal mechanisms while maintaining automatic assembly functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention divides the assembly system into separate components: assembly parts with foldable walls, elastic bands, and grooves on the display body. This segmentation allows each component to have a simple, specialized function rather than requiring a complex integrated internal structure, reducing overall device complexity while enabling automatic assembly.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If conventional display devices use complex assembly details for self-supporting characteristics, then self-supporting function is achieved, but ease of manufacture decreases

Engineering Contradiction:
Improveself-supporting characteristicVSAvoidassembly details
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent uses thin wrinkle-formed structures and flexible foldable walls made from simple materials like cardboard or thin plastic. These thin flexible elements provide the necessary self-supporting characteristics through their geometric configuration rather than through complex rigid internal structures, making them easy to manufacture and assemble.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The invention employs curved wrinkles and folded geometries in the assembly parts and display body that create self-supporting structures through shape alone. These curved and folded forms provide structural stability without requiring complex internal reinforcement, simplifying manufacturing while maintaining self-supporting characteristics.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Extent of automation

If conventional display devices have complex internal complementary structures for automatic opening, then automatic opening function is achieved, but ease of operation and assembly/disassembly decreases

Engineering Contradiction:
Improveautomatic openingVSAvoidassembly and disassembly
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The patent implements a self-service system where the elastic bands automatically tension the foldable walls of the assembly parts to open the display, and the same elastic bands enable easy closing by simply pressing the parts together. This eliminates complex control mechanisms while maintaining automatic opening and easy operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention uses dynamic foldable walls that can transition between folded and extended states, and elastic bands that dynamically adjust tension. This dynamic behavior enables automatic opening without complex mechanisms and allows easy manual closing, improving ease of operation while maintaining automation.

Inventive Principle:
Principle #15Dynamics

AI summary

Improvement in display for automatic assembly system wherein one automatic assembly part (1 1) formed by two walls (12) with wrinkles ( 13), agreeing by means of other wrinkles (14) to two walls (15) separated from each other by their free edges (16), form one hinging part in a system of tweezers. The part (1 1 ), by means of grooves (17) and (18) on its walls (12), receives an elastic band (19) inserted in hook-shaped grooves (8) and (10) of the juxtaposed rims (4), (5) and (6), (7) of both parts composing the body of the display (1). The part (1 1), by its walls (12) and walls (15), respectively accommodates between internal faces and the folds of the rims (4), (5) and (6), (7) of parts (2) and (3) composing the body of the display (1 ). Therefore, by means of working in form of tweezers combined to the elastic action, the part (1 1) may extend and become plain when the display ( 1) is closed and folded, while, after being vertically positioned and just a slight opening of its parts (2) and (3), they are automatically put apart from each other by hinging the walls (12) and (15) of the part (1 1), causing the display to be automatically assembled.
