Solution Overview

Problem

Existing lumbar support mechanisms in adjustable beds fail to adaptively adjust to user posture changes, providing inadequate support for the lower back and lack massage functions to alleviate muscle fatigue.

Innovation Solution

A lumbar support mechanism with a lumbar lifting assembly and actuator that adjusts the lumbar support member's height and incorporates massage members to conform to the user's lower back, ensuring continuous support and massage relief.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing lumbar support mechanisms are used, then basic lumbar support is provided, but they fail to adaptively adjust to user posture changes resulting in inadequate support

Engineering Contradiction:

Improveadaptive adjustment to user postureVSAvoidlumbar support effectiveness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The lumbar support mechanism incorporates a lifting assembly with movable components that enable dynamic adjustment of the lumbar support member's position and angle. The lifting actuator drives the lumbar support member to move relative to the backrest, allowing the system to adapt to different user postures and maintain effective lumbar support throughout posture changes.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If existing lumbar support mechanisms are used, then structural support is provided, but they lack massage functions to alleviate muscle fatigue

Engineering Contradiction:

Improvemassage function integrationVSAvoidmechanism structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the lumbar support function with a massage function by integrating a massage member onto the lumbar support member. The lifting assembly serves dual purposes: providing structural lumbar support and enabling the massage member to contact and massage the user's lumbar region, thereby combining two functions into one integrated system.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If lumbar support member is made fixed, then structural stability is provided, but it cannot maintain contact with lower back across varying postures

Engineering Contradiction:

Improveposture adaptationVSAvoidsupport member stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The lumbar support member is designed as a dynamic component that can move relative to the backrest through the lifting assembly. This movement capability allows the support member to maintain contact with the user's lower back across varying postures while the overall mechanism provides stable support through controlled actuation.

Inventive Principle:

Principle #15Dynamics
