Solution Overview

Problem

Existing bed designs lack an adjustable backrest that can be easily repositioned and installed on any bed frame, compromising user comfort and ease of use.

Innovation Solution

A bed with a slidingly attachable backrest assembly that includes a padded backboard, featuring mounting members that allow the backrest to be adjusted along the bed frame, making it easy to install and maintain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a bed includes a fixed backrest design, then the structure is simple and easy to manufacture, but the user cannot adjust the backrest position for comfort

Engineering Contradiction:

Improvebackrest position adjustmentVSAvoidbackrest assembly structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The backrest assembly is designed to be movable along the bed frame rather than fixed, allowing dynamic adjustment of position. The mounting members enable the backrest to slide to different locations on the frame, transforming a static structure into a dynamic one that adapts to user needs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The backrest assembly is separated into distinct components including the backrest itself, mounting members, and the bed frame structure. This segmentation allows independent adjustment of the backrest position while maintaining structural integrity, resolving the contradiction between adjustability and complexity.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If a bed includes a repositionable backrest with sliding attachment, then user comfort is improved, but the installation complexity increases

Engineering Contradiction:

Improvebackrest repositioningVSAvoidinstallation process

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The sliding attachment mechanism allows the backrest to be dynamically repositioned along the frame after installation. This dynamic design provides flexibility for users to adjust the backrest to their preferred position without requiring complex tools or procedures.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mounting members are designed with universal compatibility to attach to various bed frame configurations. This multi-functional design allows the same backrest assembly to be installed on different frame types, simplifying the overall installation process while maintaining repositioning capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If a bed includes a padded backboard for comfort, then user comfort is improved, but the manufacturing cost increases

Engineering Contradiction:

Improveuser comfortVSAvoidmanufacturing cost

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

Padding is applied locally to the backboard surface that directly contacts the user, rather than throughout the entire structure. This localized application of soft material provides comfort where needed while minimizing additional manufacturing costs and material usage.

Inventive Principle:

Principle #3Local quality
