Solution Overview

Problem

Existing adjustable electric beds have complex mechanical structures and drive systems, making them costly to produce, difficult to assemble, and maintain, while also being heavy and cumbersome.

Innovation Solution

An adjustable electric bed design featuring a bed frame with articulated bed boards and a simplified motor system, where the head and leg motors drive the bed boards to adjust position, reducing mechanical complexity and weight, and using a movable support bar for ergonomic support, with a bed frame made of cold-drawn steel for strength and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex mechanical structure and numerous rotational stands, power plants, support bars, support lugs and actuating gears are used to drive the bed board, then the bed board position can be adjusted, but the device complexity increases and manufacturing cost rises

Engineering Contradiction:

Improvebed board position adjustmentVSAvoidmechanical structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex mechanical transmission components (rotational stands, power plants, support lugs, actuating gears) from the traditional bed structure, retaining only the essential elements (bed frame, bed boards, and driving motors) needed to achieve position adjustment functionality

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the complex mechanical transmission system with a simplified direct-drive motor system, where driving motors directly articulate with bed boards to achieve position adjustment without intermediate mechanical components

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If complex mechanical structure with numerous components is used, then bed board position adjustment is achieved, but ease of manufacture deteriorates and assembly becomes troublesome

Engineering Contradiction:

Improvebed board position adjustmentVSAvoidassembly convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent removes numerous mechanical components (rotational stands, power plants, support lugs, actuating gears) that complicate manufacturing and assembly, leaving only the essential bed frame, bed boards, and driving motors

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges multiple separate mechanical components into integrated assemblies, where driving motors directly articulate with bed boards, eliminating the need for separate transmission mechanisms and reducing assembly steps

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If complex mechanical structure with numerous components is used, then bed board position adjustment is achieved, but ease of repair deteriorates

Engineering Contradiction:

Improvebed board position adjustmentVSAvoidmaintenance convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of repair

Solution Approach 1:

The patent extracts and removes complex mechanical transmission components that would require specialized knowledge for maintenance, leaving only driving motors and simple articulation joints that are easier to diagnose and repair

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The simplified structure with direct motor-to-bed-board articulation allows users to perform basic maintenance and troubleshooting without requiring specialized mechanical knowledge or tools

Inventive Principle:

Principle #25Self-service

4Device complexity

If simplified motor system with head motor and leg motor directly articulating with bed boards is used, then device complexity is reduced, but driving force may be insufficient

Engineering Contradiction:

Improvemechanical structure simplicityVSAvoiddriving force

Core Design Contradiction:

Device complexityVSPower

Solution Approach 1:

The patent divides the driving function into multiple independent driving motors (head motor for head bed board, leg motor for leg bed board) that work simultaneously, distributing the total driving force requirement across multiple units rather than relying on a single complex transmission system

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs articulated connections between motors and bed boards that allow dynamic adjustment of force application angles and leverage, enabling the motors to generate sufficient effective driving force through geometric advantage rather than mechanical multiplication

Inventive Principle:

Principle #15Dynamics
