Solution Overview

Problem

Existing fittings for attaching hammocks to walls can cause damage to the wall and/or the hammock during height adjustment due to unwanted contact between the hanging furniture and the wall or hammock.

Innovation Solution

A fitting system with a length-adjustable drive unit and a supporting element arranged orthogonally between the first fitting part and the rear wall of the hanging furniture, which includes a sliding or rolling element to prevent vertical contact and allow for inclination and height adjustment of the hammock, using an electromechanical lifting column and adjustable positioning units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the hanging furniture is moved vertically for height adjustment, then the height adaptability is improved, but unwanted contact between the furniture and wall occurs causing damage

Engineering Contradiction:
Improveheight adjustment capabilityVSAvoidwall damage and furniture damage
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A support element is introduced as an intermediary component between the hanging furniture and the wall-mounted fitting. This support element prevents direct contact between the furniture and wall during vertical adjustment, thereby eliminating the harmful contact while enabling height adjustment. The support element acts as a mediator that allows controlled movement without damage.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a support element is added to prevent contact, then damage prevention is improved, but the device complexity increases

Engineering Contradiction:
Improvedamage preventionVSAvoidfitting structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The support element is designed to perform multiple functions simultaneously: it prevents contact between the furniture and wall during adjustment, provides structural support for the hanging furniture, and enables controlled vertical movement. By combining these functions into a single component, the design avoids adding excessive complexity while achieving damage prevention.

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

3Adaptability or versatility

If the support element is made adjustable, then the inclination adjustment capability is improved, but the device complexity increases

Engineering Contradiction:
Improveinclination adjustment capabilityVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support element is designed with adjustable positioning capabilities that allow it to adapt to different inclination angles of the hanging furniture. The adjustability is implemented in a way that maintains structural simplicity, enabling the support element to follow the furniture's inclination while preventing contact during adjustment movements.

Inventive Principle:
Principle #15Dynamics

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

Prevents damage to the wall and hammock by allowing smooth height and inclination adjustments with low friction, ensuring secure and damage-free operation.

Implementation Method 1

The support element is designed as a sliding element or roller element, especially as a rolling body. This enables a low -friction of the hammock to adapt it to the height adjustment of it.

Methodology Applied
Scientific EffectFriction: Friction
