Solution Overview

Problem

Existing walker designs lack versatile and easy-to-use seating options that can be conveniently attached and removed, often requiring complex hardware and interfering with other walker components.

Innovation Solution

A walker seat assembly with a detachable seat bottom and a mounting member that includes telescoping segments and springs, allowing for easy attachment and detachment without tools, and enabling the seat to rotate and adjust to different positions for comfortable sitting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a removable seat is added to a walker, then seating functionality is improved, but the device complexity increases due to required hardware mechanisms

Engineering Contradiction:

Improveseating functionalityVSAvoidhardware mechanisms

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The seat assembly is divided into separate components: a seat bottom, a mounting member with telescoping segments, and attachment mechanisms. This segmentation allows the seat to be easily attached and removed while keeping each component simple in design. The mounting member itself is segmented into telescoping parts that can extend and retract independently.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting member incorporates telescoping segments that can dynamically extend and retract to adjust the seat position and accommodate different walker configurations. This dynamic capability provides versatility without requiring complex fixed-structure hardware, as the telescoping action is achieved through simple spring-loaded mechanisms.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a removable seat is added to a walker, then seating functionality is improved, but the ease of operation deteriorates due to complicated attachment and detachment procedures

Engineering Contradiction:

Improveseating functionalityVSAvoidattachment and detachment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The attachment and detachment mechanisms are designed to be self-operating without requiring tools or complex procedures. The spring-loaded attachment members automatically engage with corresponding receptacles on the walker frame, and can be easily released by simple manual action. This self-service design allows users to attach and detach the seat independently and quickly.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The mounting member acts as an intermediary component between the seat bottom and the walker frame. It includes attachment members that mediate the connection process, providing a simple interface for attachment and detachment. This intermediary mechanism simplifies the interaction between the user, seat, and walker, making the operation intuitive and easy.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a removable seat is added to a walker, then seating functionality is improved, but it may interfere with other walker components such as hand grips

Engineering Contradiction:

Improveseating functionalityVSAvoidinterference with walker components

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

4Reliability

If a seat is customized or integrated into a particular walker, then the seating is stable and functional, but the adaptability to different walkers is reduced

Engineering Contradiction:

Improveseating stabilityVSAvoidcompatibility with different walkers

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mounting member is designed with universal attachment capabilities that can interface with various walker frame configurations. The telescoping segments and standardized attachment receptacles allow the same seat assembly to be reliably mounted on different walker models, providing both stability and adaptability simultaneously.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A walker seat may include a seat bottom and a support structure. The seat bottom may include an anterior region, a posterior region, an upper side, and a lower side. The lower side may include a central segment retention portion. The support structure may include a central segment, a left-side segment, and a right-side segment. The central segment may be retained by the central segment retention portion. The left-side segment may be extendable from a left side of the central segment, whereby the left-side segment extends beyond a left side of the seat bottom. Similarly, the right-side segment may be extendable from a right side of the central segment, whereby the right-side segment extends beyond a right side of the seat bottom.
