Medical Table Accessory Locking Mechanism for Limited-Angle Spar Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for attaching medical procedure table accessories require 360-degree access, interfering with spar functionality and are time-consuming, lacking ease of use and dexterity.
Innovation Solution
A locking mechanism with a cam-shaped grip that automatically secures accessories to table spars upon seating, allowing easy attachment and removal without interfering with spar functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a C-shaped clamp or Velcro strap is used to attach accessories to table spars, then accessories can be secured to the table, but 360-degree access is required which interferes with spar functionality and increases attachment time
Solution Approach 1:
The attachment system is divided into separate functional components: the accessory base with integrated locking mechanism and the table spar. The locking mechanism includes a cam-shaped grip that engages with the spar, allowing attachment from limited angles without requiring 360-degree access. This segmentation enables the accessory to be attached while maintaining spar functionality.
Solution Approach 2:
The locking mechanism is pre-integrated into the accessory base structure, with the cam-shaped grip positioned to automatically engage the spar upon lowering the accessory into place. This preliminary configuration eliminates the need for separate attachment steps and reduces the time required to secure accessories.
2Reliability
If a C-shaped clamp or Velcro strap is used to attach accessories to table spars, then accessories can be secured to the table, but significant time and effort are required along with care and dexterity
Solution Approach 1:
The locking mechanism is designed to automatically secure the accessory to the spar through the cam-shaped grip that engages when the accessory is lowered into place. This self-securing mechanism eliminates the need for manual adjustment or complex attachment procedures, reducing the effort and dexterity required while maintaining reliable attachment.
Solution Approach 2:
The locking mechanism utilizes a cam-shaped grip that transforms the lowering motion of the accessory into a locking action. As the accessory is lowered, the cam geometry converts vertical movement into radial engagement force, automatically securing the accessory without requiring manual tightening or adjustment.
3Adaptability or versatility
If conventional attachment methods are used, then accessories can be attached to table spars, but the spars cannot be used to support the table top effectively
Solution Approach 1:
The locking mechanism is designed with a localized cam-shaped grip that engages the spar at a specific point, allowing accessory attachment without requiring access to the entire spar circumference. This localized engagement point preserves the spar's structural integrity and functionality for supporting the table top while enabling accessory attachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick, secure attachment and removal of accessories without hindering spar use, reducing staff effort and ensuring ease of customization.
Implementation Method 1
A locking mechanism includes a cam-shaped locking grip that can rotate about a center of rotation to a locked position in which the locking grip compresses against the spar
Implementation Method 2
the locking grip compresses against the spar... securing the accessory to the spar

AI summary
A medical procedure table has parallel spars supported by the base of the table. A number of accessories, such as table top segments, retractors, support pads, etc. can be removably attached at desired locations along the spars. Each accessory has a base with at least one downwardly-extending lip defining a channel for removably seating the accessory over at least one spar. A locking mechanism extends from the base of the accessory adjacent to the channel to automatically grip the spar between the locking mechanism and the lip as the accessory is seated over the spar. The locking grip mechanism can be manually released to reposition or remove the accessory.
