Solution Overview

Problem

Conventional plastic and metal hooks used for displaying goods are expensive and difficult to recycle, often ending up in landfills where they persist for years, posing environmental concerns.

Innovation Solution

A paper-based peg hook structure that can be easily recycled or biodegrades quickly, featuring a paper anchor and elongated support structure made from multiple layers of paperboard, with optional features like detachable slot blocking segments and multiple hooks, designed for secure attachment to display fixtures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If plastic or metal hooks are used for displays, then the hooks provide durable and reusable functionality, but they are expensive and difficult to recycle, causing environmental pollution

Engineering Contradiction:

Improvehook durabilityVSAvoidenvironmental pollution

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from synthetic plastic/metal to natural paperboard, fundamentally altering the environmental characteristics while maintaining structural functionality for display hooks

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent adopts a disposable paperboard hook that can be easily discarded and replaced, eliminating the need for complex recycling processes and reducing environmental accumulation of non-biodegradable materials

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Strength

If plastic or metal hooks are used for displays, then the hooks maintain structural strength, but they require removal from displays for recycling and linger in landfills for years

Engineering Contradiction:

Improvehook strengthVSAvoidlandfill persistence

Core Design Contradiction:

StrengthVSDuration of action of stationary object

Solution Approach 1:

The patent uses multi-layer paperboard construction with different layer orientations and bonding methods to achieve sufficient structural strength while maintaining biodegradability and short landfill persistence

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent divides the hook into multiple functional segments (anchor portion, support structure, hanging surface) that can be formed from segmented blank portions, allowing optimized material usage and structural integrity with minimal material

Inventive Principle:

Principle #1Segmentation

3Strength

If multiple layers of paperboard are used to form the hook, then the hook achieves sufficient strength and rigidity, but the manufacturing process becomes more complex

Engineering Contradiction:

Improvehook strengthVSAvoidmanufacturing complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent combines multiple blank portions into a single integrated hook structure through adhesive bonding, simplifying the manufacturing process by eliminating separate production and assembly steps for different components

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An environmentally friendly peg hook made from a paper based material that can be used on a display. The paper material can be recycled or is degradable in a land fill. The peg hook includes an anchor structure for securing the peg hook to a wall of a display through a slot in the wall. The peg hook can include a single hook structure or multiple hook structures in a single row or multiple rows.
