Solution Overview

Problem

Personal weed grinders are large and inconvenient to use, requiring a mediator element to transfer ground weed to smoking paper, which is not efficient.

Innovation Solution

A compact weed grinder with a single board and folding mechanism that allows for grinding and direct pouring of ground weed into smoking paper without a mediator, using movable grinding plates and a handle for easy operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional personal weed grinder is used, then grinding function is provided, but the device becomes large and inconvenient to carry

Engineering Contradiction:
Improveconvenience to carryVSAvoidsize of grinder
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The grinder is divided into multiple folding panels that can be collapsed into a compact form. The single board comprises at least four panels with folding lines, allowing the device to be folded into a small size for pocket carrying while maintaining full functionality when deployed

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The grinder utilizes a folding mechanism that transforms the device from a flat 2D configuration to a 3D functional structure. When folded, the panels collapse into a compact form; when unfolded, they create the necessary volume for grinding and collection chambers

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If a mediator element is used to transfer ground weed, then transfer is possible, but the process becomes inconvenient and less efficient

Engineering Contradiction:
Improveefficiency of weed transferVSAvoidconvenience of use
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The mediator element is completely removed from the system. The design enables direct transfer of ground weed from the grinding chamber to the collection chamber through the folding mechanism itself, eliminating the need for paper or other intermediary materials

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The folding mechanism serves dual purposes: it provides the structural framework for the grinder and simultaneously acts as the transfer mechanism for ground weed. The panels themselves guide and direct the ground material from grinding to collection areas without requiring separate transfer components

Inventive Principle:
Principle #25Self-service

3Volume of moving object

If grinding plates are positioned close to folding lines for compactness, then device size is reduced, but weed cannot be poured out easily

Engineering Contradiction:
Improvecompactness of deviceVSAvoidease of pouring out ground weed
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

Different regions of the panels serve different functions: areas near folding lines provide structural support and compactness, while designated non-grindable areas are positioned to facilitate weed pouring. The grinding plates are strategically positioned to leave clear pathways for material flow

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables efficient grinding and transfer of weed into smoking paper without the need for a mediator, maintaining weed quality and providing a compact, pocket-sized design.

Implementation Method 1

at least one of the two grinding plates may be movable in linear motion with respect to the other

Methodology Applied
Scientific EffectLinear motion:

Implementation Method 2

to partly deploy the single board for directing pouring of the weed once being ground, out of the single board by gravity, through the at least one folding line

Methodology Applied
Scientific EffectGravity: Gravitation

AI summary

A pocket sized weed grinder is provided herein. The weed grinder comprises a single board, comprising at least four panels, at least one folding line disposed between adjacent panels of the at least four panels, for forming a closed flat cell between two of the adjacent panels, and two grinding plates, each grinding plate disposed on each of two of the adjacent panels. At least one of the two grinding plates is movable in linear motion with respect to the other. The weed grinder enables grinding of weed, accumulating the ground weed within the weed grinder and pouring the ground weed to a smoking paper, while avoiding the need of a mediator element to which ground weed is poured and from which ground weed is poured into a smoking paper, as in currently used weed grinders.
