Solution Overview

Problem

Traditional hooks damage surfaces when used to hang ornaments and pose safety hazards, and most hooks are single-purpose and contribute to resource waste after use.

Innovation Solution

A multi-functional hook with a body portion, positioning portion, and hook portion arranged on its back surface, featuring rotating shafts and limiting portions for safe attachment and adjustable use as an ornament, reducing surface damage and waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional nail is used to hang an ornament, then the ornament can be securely attached, but the surface of the household object is damaged and there are safety hazards

Engineering Contradiction:
Improvesecure attachmentVSAvoidsurface damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a hook as an intermediary device between the ornament and the household object surface. The hook attaches to the edge or protrusion of the object without penetrating or damaging the surface, while providing secure attachment for the ornament through its curved structure. This mediator approach resolves the contradiction by achieving reliable attachment without direct harmful contact to the surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The hook is designed with a flexible, thin structure that can bend and conform to the edge or protrusion of the household object. This flexibility allows the hook to wrap around or clamp onto the edge without causing damage, while maintaining sufficient strength to hold the ornament securely. The thin profile minimizes surface interference and damage risk.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If a traditional nail is used to hang an ornament, then the ornament can be securely attached, but there are potential safety hazards from scraping or impact

Engineering Contradiction:
Improvesecure attachmentVSAvoidsafety hazards
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The flexible, thin construction of the hook eliminates the rigid, protruding characteristics of traditional nails that cause scraping and impact hazards. The hook's flexible nature allows it to conform to surfaces and reduce the risk of accidental contact with users, while still providing secure ornament attachment through its structural design.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

By positioning the hook as an intermediary that attaches to the object edge rather than penetrating the surface, the design removes the hazardous exposed tip characteristic of nails. The hook mediates between the ornament weight and the object surface, eliminating direct safety hazards to users while maintaining secure attachment functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a single-purpose hook is used, then the hook can perform its hanging function, but the hook becomes waste after Christmas or when not needed

Engineering Contradiction:
Improvehanging functionVSAvoidresource waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The hook is designed with multiple functions: it can hang ornaments during Christmas, serve as a decorative ornament itself after the holiday season, and be folded for compact storage or gifting. This multi-functionality transforms the single-purpose hook into a versatile item that provides value throughout the year, eliminating resource waste by extending the product's useful life beyond its original holiday purpose.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of discarding the hook after Christmas use, the design enables recovery and reuse as a decorative ornament. The hook's aesthetic design allows it to be displayed as holiday decor in subsequent years, recovering its value and preventing it from becoming waste. This extends the product lifecycle and reduces resource consumption.

Inventive Principle:
Principle #34Discarding and recovering

4Stability of the object's composition

If a rigid hook structure is used, then the hook provides stable support, but the hook cannot be folded for storage or transportation

Engineering Contradiction:
Improvestable supportVSAvoidstorage complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The hook incorporates dynamic, movable joints that allow the structure to transition between a rigid extended configuration for stable ornament support and a folded compact configuration for storage and transportation. The movable connections maintain structural integrity and stability when extended, while enabling easy folding when not in use, resolving the contradiction between stability and storage convenience.

Inventive Principle:
Principle #15Dynamics
