Solution Overview

Problem

Traditional piñatas face issues with uneven distribution of contents, structural integrity, and the need for adhesives or solid materials, limiting their use indoors and outdoors.

Innovation Solution

A compartmentalized piñata structure using cardboard or plastic components without adhesives, featuring a center tube and vertical columns for even content distribution and support, allowing for safe indoor and outdoor use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional piñatas are made with solid materials like clay or require adhesives and staples, then structural integrity is improved, but safety for indoor use deteriorates due to potential hazards from breaking solid materials

Engineering Contradiction:
Improvestructural integrityVSAvoidsafety for indoor use
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent uses cardboard as the primary material, which is inherently safe for indoor use as it breaks into harmless pieces rather than sharp fragments like clay or plastic. The structure is designed to be disposable after use, with the cardboard body collapsing safely to release contents without creating hazards.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent combines multiple cardboard components (body, bottom, center piece, vertical columns) into a composite structure that achieves structural integrity through geometric design and interlocking mechanisms rather than relying on solid materials or adhesives. The compartmentalized design with vertical columns creates a framework that maintains strength while using only safe cardboard material.

Inventive Principle:
Principle #40Composite materials

2Strength

If traditional piñatas use adhesives, staples, or solid materials for construction, then structural integrity is improved, but ease of assembly deteriorates due to complex assembly processes requiring these materials

Engineering Contradiction:
Improvestructural integrityVSAvoidease of assembly
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The piñata is divided into separate modular components (body, bottom, center piece, vertical columns) that can be independently prepared and then easily assembled. Each component is pre-cut with slot openings that align to form interlocking joints, eliminating the need for adhesives or staples while maintaining structural integrity through the geometric fit of the segmented parts.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If traditional piñatas are made as single compartments, then manufacturing simplicity is improved, but even distribution of contents during spinning deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoideven distribution of contents
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The interior space is divided into multiple compartments by vertical columns that extend from the center piece to the top. These columns create separate chambers that distribute contents more evenly throughout the structure. During spinning, the centrifugal force acts on multiple smaller compartments rather than one large space, preventing content accumulation and ensuring more uniform distribution and release.

Inventive Principle:
Principle #1Segmentation

4Ease of manufacture

If traditional piñatas lack internal support structures, then manufacturing simplicity is improved, but structural stability during spinning deteriorates causing bottom collapse from excess weight

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidstructural stability during spinning
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The bottom and center piece are constructed with integrated support structures (vertical columns and horizontal reinforcements) before the piñata is filled with contents. This preliminary structural framework is built into the cardboard components during manufacturing, providing preemptive support against the weight of contents and centrifugal forces during spinning, preventing bottom collapse without requiring additional materials or complex assembly.

Inventive Principle:
Principle #10Preliminary action

AI summary

Systems and methods are disclosed that include providing a piñata with an improved piñata structure. The piñata structure includes a top, a bottom, and a center piece, each having a plurality of slots extending radially inward from a perimeter. A plurality of vertical column components engage the top, bottom, and centerpiece via complementary aligned upper, lower, and middle slots to form compartments in the piñata structure that can be filled with candy or confetti. A tube extending through the center of the piñata structure includes a string passing therethrough and coupled to an anchoring object at the bottom of the piñata structure. The string serves as an axis of rotation for the piñata structure. Tape, streamer, ribbon, or a combination thereof is wrapped around the piñata structure in consecutive layers and when peeled, the piñata rotates and expels the contents of the piñata structure.
