Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical body position retaining belt securing devices lack pre-tightening force, are not adaptable to side guide rails at angles of 30°, and require bolts for securing, which are time-consuming and difficult to clean.
Innovation Solution
A medical body position retaining belt securing device comprising an upper clamping piece, a lower clamping piece, and an elastic piece, where the clamping pieces are coupled to the belt and equipped with clamping portions for securing to the side guide rail, using an elastic force to maintain clamping and release the belt, eliminating the need for bolts and allowing installation at any position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a sheet metal bent structure is used to realize gravity self-locking, then the structure is simple, but it cannot provide pre-tightening force and slides when the side guide rail forms an angle of 30° with the horizontal plane
Solution Approach 1:
The elastic piece is pre-compressed between the upper and lower clamping pieces to generate preliminary clamping force before the device is installed on the side guide rail. This pre-tightening action ensures that the clamping portions maintain continuous contact with the guide rail surface, preventing sliding even when the rail is inclined at 30° to the horizontal plane.
Solution Approach 2:
The device transforms the static gravity-based locking mechanism into a dynamic elastic force-based clamping system. By changing from gravity-dependent normal force to elastic piece-generated clamping force, the device maintains reliable attachment under varying angular conditions (0°-30° inclination) without sliding.
2Reliability
If bolts are used to realize locking and securing, then the securing is reliable, but it is time-consuming and not easy to clean
Solution Approach 1:
The elastic piece automatically generates and maintains the clamping force between the upper and lower clamping pieces without requiring external fastening operations. The device self-secures to the side guide rail through the elastic recovery force, eliminating the need for manual bolting operations and subsequent cleaning of bolt threads and holes.
Solution Approach 2:
The invention extracts and eliminates the bolt fastening system from the device structure. By removing bolts, threaded holes, and associated fastening mechanisms, the device achieves both improved installation efficiency (no bolting required) and ease of cleaning (no hidden crevices or threads), while maintaining securing reliability through the elastic clamping mechanism.
3Device complexity
If a sheet metal bent structure is used, then the structure is simple, but it cannot be installed at any position on the side guide rail and cannot adapt to side guide rails of different operating tables
Solution Approach 1:
The clamping portions are designed with universal geometric features that can engage with the flanged ends of side guide rails regardless of the specific operating table model or installation position. The elastic clamping mechanism provides adjustable clamping force to accommodate different rail dimensions and positions, enabling the device to be installed anywhere on the side guide rail within the elastic piece's expansion range.

Implementation Method 1
the elastic piece moves the clamping portion of the upper clamping piece and the clamping portion of the lower clamping piece towards each other by virtue of an elastic force thereof
Implementation Method 2
the elastic force of the elastic piece is overcome to move the clamping portion of the upper clamping piece and the clamping portion of the lower clamping piece away from each other
