Solution Overview

Problem

Existing drawer inserts, whether made entirely of plastic or wood, fail to provide a visually appealing, haptically pleasant, and design-friendly solution that minimizes noise and slipping issues when storing cutlery, due to limitations in material choice and production complexity.

Innovation Solution

A drawer insert comprising a wooden outer frame with a flexible plastic inner part, specifically a trough-shaped receptacle made of synthetic rubber, thermoplastic elastomer, or thermoplastic polyurethane, which provides stability and reduces noise and slipping, allowing for modular design options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If drawer inserts are made entirely of hard plastic to ensure dimensional stability, then stability is improved, but noise and haptic comfort deteriorate

Engineering Contradiction:
Improvedimensional stabilityVSAvoidnoise and haptic discomfort
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The drawer insert combines two different materials: a hard plastic outer frame for dimensional stability and a soft inner part for noise reduction and haptic comfort. This composite structure allows each material to fulfill its optimal function without compromising the other.

Inventive Principle:
Principle #40Composite materials

2Shape

If drawer inserts are made of wood for visual appeal, then aesthetics are improved, but design flexibility and noise reduction deteriorate

Engineering Contradiction:
Improvevisual appealVSAvoiddesign flexibility
Core Design Contradiction:
ShapeVSAdaptability or versatility

Solution Approach 1:

The combination of wood outer frame and plastic inner part allows the wooden aesthetic to be preserved while the plastic provides design flexibility and noise reduction capabilities that wood alone cannot achieve.

Inventive Principle:
Principle #40Composite materials

3Object-generated harmful factors

If the inner part is made of flexible plastic to reduce noise, then noise reduction is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvenoise levelVSAvoidmanufacturing simplicity
Core Design Contradiction:
Object-generated harmful factorsVSEase of manufacture

Solution Approach 1:

The drawer insert is divided into two separate components: the outer frame and the inner part. This segmentation allows each part to be manufactured independently using suitable processes, then assembled together, balancing noise reduction requirements with manufacturing feasibility.

Inventive Principle:
Principle #1Segmentation

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

The solution offers a stable, noise-reduced, and haptically pleasing drawer insert with flexible design possibilities, as the wooden frame ensures dimensional stability while the flexible plastic inner part absorbs shocks and reduces noise, enhancing user experience.

Implementation Method 1

The inner part ( 14 ) consists of a flexible plastic material, for example of a synthetic rubber or a thermoplastic elastomer... the pieces of cutlery cause unpleasant noises when they are placed in such drawer inserts made of hard plastics... the flexible plastic material from which the inner part is made can be at least so soft and flexible that the objects lie softly and do not cause any hard recoil or knocking noises
