Bedside guardrail with a folding table board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bedside guardrails are integrated with the bed and become obstacles when not needed, complicating tasks like changing sheets or providing a dining surface for patients.
Innovation Solution
A bed guardrail with a folding table board that includes a rotating feature allowing the table board to pivot around a rotary axis, enabling it to switch between a parallel position to the ground for use and a position facing away from the bed for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bedside guardrails are integrated with the bed, then the blocking function is improved, but the ease of operation deteriorates when guardrails are not needed
Solution Approach 1:
The guardrail is designed with a reversible structure that allows it to switch between a blocking state (providing safety) and a non-blocking state (facilitating nursing operations). The guardrail can be quickly reversed or removed by nursing staff, transforming from a static obstacle to a dynamic element that adapts to different operational needs.
2Adaptability or versatility
If a dining table function is added to the guardrail, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The dining table function is merged with the guardrail structure by integrating a table board that can be installed on the guardrail. This allows the guardrail to serve dual purposes: providing safety blocking and offering a dining surface for patients, thereby improving versatility without requiring a completely separate dining table.
Solution Approach 2:
The guardrail is designed to perform multiple functions: safety blocking, dining support, and potential storage. The table board can be installed or removed as needed, allowing the same structure to adapt to different functional requirements, thus achieving multi-functionality.
3Ease of manufacture
If the table board structure is made simple, then the ease of manufacture is improved, but the reliability may deteriorate
Solution Approach 1:
The table board is designed as a separate, detachable component that can be installed on the guardrail. This segmentation allows for simple manufacturing of individual parts while maintaining overall reliability through proper connection mechanisms. The table board can be easily manufactured and replaced if needed.

AI summary
A bed guardrail with a folding table board, the bed guardrail comprises: a guardrail and a table board with rotating features; the guardrail includes an outer frame; the rotating feature facilitates the table board to rotate around at least one rotary axis, wherein, the direction of at least one the rotary axis is the same as the extension direction of the outer frame; the table board has a relatively flat table board surface, when the table board rotates around the rotary axis, the table board has a first position and a second position; when the table board is in the first position, the table board surface remains basically parallel to the ground, when the table board is in the second position, the support direction of the table board surface faces away from the bed body.
