Solution Overview

Problem

There is a need for a structure that can aid bed departure and prevent users from falling out of bed, while also encouraging safe exit methods.

Innovation Solution

A detachable structure is designed for attachment to a bed apparatus, featuring a holder and a first frame with a columnar portion that can be adjusted in angle, serving as both a side rail to prevent falls and a grip to facilitate exit, with a second portion that can be positioned for secure weight application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed side rail structure is used to prevent falls, then safety is improved, but ease of operation for bed departure deteriorates

Engineering Contradiction:

Improvefall preventionVSAvoidbed departure

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The side rail structure is designed with dynamic adjustability, allowing the angle between the first direction (vertical support) and third direction (grip portion) to be variable. This enables the structure to transition between a stable fall-prevention configuration and an accessible bed-departure configuration, resolving the contradiction between safety and ease of operation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The structure integrates multiple functions into a single component: it serves as both a fall-prevention barrier and a grip aid for bed departure. The first portion provides vertical support for fall prevention, while the second portion extends to offer a grip surface, allowing the same structure to fulfill both safety and operational assistance roles.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a detachable structure with variable angles is added to aid bed departure, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improvebed departureVSAvoidstructure configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The structure is divided into two distinct portions: a first portion for insertion into the holder and a second portion continuous to the first. This segmentation allows each part to be optimized for its specific function while simplifying the overall attachment mechanism to the bed apparatus.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first and second portions are merged into a continuous structure that can be detachably attached as a single unit to the holder. This combining approach reduces the number of separate components and attachment steps, thereby reducing device complexity despite the variable angle capability.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

According to an embodiment, a structure is detachably attached to a bed apparatus. The bed apparatus includes a holder and a first frame that includes a portion extending in a first direction. The structure includes: a first portion of a columnar shape extending in a second direction that intersects the first direction; and a second portion continuous to the first portion and including a portion extending in a third direction that intersects the second direction. The first portion is inserted in the holder so that the holder holds the structure. When the structure is attached to the bed apparatus, an angle between the first direction and the third direction is variable. The structure that can facilitate aid of bed departure can be provided.
