Solution Overview

Problem

The gap between a conventional bed mattress and a headboard often leads to items like pillows, remote controls, and eyeglasses falling behind the bed, disrupting sleep and daily activities, as existing solutions do not effectively address this specific issue.

Innovation Solution

A triangular prism-shaped wedge made of dense, malleable material, designed to fit between the mattress and the wall or headboard, forming a lateral shelf that secures items in place using friction, with optional rubber slats for added stability and embedded stereo speakers and side pockets for storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wedge is placed in the gap between the mattress and headboard to prevent items from falling, then item security is improved, but the device complexity increases

Engineering Contradiction:
Improveitem securityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The wedge is divided into distinct functional segments: a compression resistance portion (rigid shelf) and a friction portion (softer material with rubber slats). This segmentation allows each part to perform its specific function optimally while keeping the overall design simple and effective.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different portions of the wedge have different material properties tailored to their functions: the compression resistance portion uses rigid material (density ≥ 0.05 g/cm³) to form a stable shelf, while the friction portion uses softer material (density 0.0024-0.05 g/cm³) with rubber slats to maximize friction against the headboard. This local differentiation resolves the contradiction by making the device simple yet highly effective.

Inventive Principle:
Principle #3Local quality

2Stability of the object's composition

If the wedge material is made rigid to form a stable shelf, then shelf stability is improved, but the wedge cannot conform to irregular gaps

Engineering Contradiction:
Improveshelf stabilityVSAvoidgap conformance
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The wedge is segmented into a rigid shelf portion and a compliant friction portion. The rigid portion maintains shelf stability while the compliant portion (with density 0.0024-0.05 g/cm³) can deform to match irregular gap shapes, resolving the contradiction between stability and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The shelf portion uses high-density rigid material for stability, while the friction portion uses low-density softer material for adaptability. This local quality differentiation allows the wedge to simultaneously achieve both shelf stability and gap conformance.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the wedge is made soft to conform to gaps, then adaptability is improved, but the shelf becomes less rigid

Engineering Contradiction:
Improvegap conformanceVSAvoidshelf rigidity
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The wedge separates the adaptability function (soft friction portion) from the shelf support function (rigid compression resistance portion). This segmentation allows the soft portion to conform to gaps while the rigid portion maintains shelf strength.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The friction portion uses soft material (density 0.0024-0.05 g/cm³) for gap conformance, while the shelf portion uses rigid material (density ≥ 0.05 g/cm³) for strength. This local quality assignment resolves the contradiction by giving each region the properties it needs.

Inventive Principle:
Principle #3Local quality

4Reliability

If rubber slats are added to increase friction and stability, then reliability is improved, but the device complexity increases

Engineering Contradiction:
Improvewedge stabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The rubber slats serve multiple functions simultaneously: they increase friction between the wedge and headboard, provide structural reinforcement to the friction portion, and help distribute compression forces. This multi-functionality improves reliability without adding significant complexity.

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

AI summary

A triangular prism-shaped wedge, fashioned of a sturdy foam core with soft and malleable properties, fashioned to occupy the space that commonly exists between the head of a mattress and the wall or headboard that the mattress is binding against. It is configured to occupy this space, aided via the force of friction, to ensure that items such as pillows, remote controls, and other bedside items do not fall behind the mattress, and onto the floor. It may be configured with an assortment of interchangeable pockets, as well as an embedded stereo speaker system.
