Bed Rail with Rotating Table Board for Blocking and Dining Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bedside guardrails are cumbersome and complicated, lacking a convenient mechanism to accommodate the blocking function when not needed, and fail to provide a practical dining solution for patients.
Innovation Solution
A bed rail with a guardrail and table board design featuring a rotating mechanism and multi-axis rotating device, allowing the guardrail to pivot between blocking and accommodating positions, and the table board to switch between use and storage states, ensuring easy operation and meal support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bedside guardrails are integrated with the bed, then the blocking function is provided, but the guardrails become an obstacle when not needed and increase the difficulty of replacing sheets or mattresses
Solution Approach 1:
The guardrail is designed with a reversible mechanism that allows it to dynamically change position between a blocking state (providing safety) and a folded state (clearing the way for nursing operations). The foldable structure enables the guardrail to be easily moved aside when not needed, resolving the contradiction between providing reliable blocking and facilitating ease of operation during nursing tasks.
2Adaptability or versatility
If a reversible guardrail is used, then the blocking function can be accommodated, but the structure becomes complicated and the quality increases
Solution Approach 1:
The guardrail is divided into multiple segments that can fold relative to each other. This segmentation allows the guardrail to transform from an extended blocking configuration to a folded compact configuration, providing reversibility while keeping each individual segment structurally simple. The segmented design avoids the need for complex mechanical mechanisms.
3Adaptability or versatility
If a dining table function is added to the guardrail, then patient convenience is improved, but the structure becomes cumbersome and the failure rate increases
Solution Approach 1:
The guardrail structure is designed to serve multiple functions: it provides patient safety through blocking, facilitates nursing operations through reversibility, and supports dining activities through an integrated table surface. By making the guardrail itself support the table function rather than adding a separate complex mechanism, the design achieves multi-functionality while maintaining structural simplicity and reliability.

AI summary
The present invention provides a bed rail with table, which comprises a guardrail and a table board, wherein the guardrail consists of an outer frame with an inner extension arm and a fixed end which can be attached to a bed body; and the table board comprises a relatively flat table board surface and a rotation restricting part which is pivotally attached to the outer frame to rotate between a first position and a second position around a first axis.
