Bottle Holder Clamping Slide for Variable Infusion Bottles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle holders for injection or infusion devices are limited in accommodating storage bottles of different sizes, as they often require specific diameters and lack secure fixation, leading to difficulties in inserting larger bottles and unreliable arm positioning.
Innovation Solution
A bottle holder with a base body featuring a clamping slide preloaded with a spring, which is linearly displaceable and has a locking mechanism with a resilient nose and stop face, allowing for secure locking and easy adjustment to fit various bottle sizes, along with a handle for manual operation and flexible arms for accommodating different diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed diameter bottle mounts are used on outer and inner arms, then two specific bottle sizes can be accommodated, but storage bottles of different sizes cannot be used
Solution Approach 1:
The bottle holder employs a movable clamping slide that can be adjusted to different positions along the arm, allowing the effective diameter of the bottle mount to change dynamically. This enables accommodation of bottles with different diameters without requiring multiple fixed-size holders, thus improving versatility while maintaining relatively simple structure.
Solution Approach 2:
The invention changes the parameter of bottle holder diameter by allowing the clamping slide to move to different positions. By adjusting the position of the clamping slide along the arm, the effective gripping diameter is varied to match different bottle sizes, resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If inner arms are pivotably mounted to accommodate different bottle sizes, then larger bottles can be fitted, but the inner arms may unintentionally swivel and the bottle neck is not securely fixed
Solution Approach 1:
The clamping slide is spring-preloaded to automatically exert clamping force on the bottle neck when inserted. The spring mechanism provides self-adjusting pressure that secures the bottle neck reliably without requiring additional locking operations or complex positioning mechanisms, thus improving both reliability and ease of use.
Solution Approach 2:
The invention replaces the pivotable arm mechanism with a linearly movable clamping slide guided in a shaft. This substitution eliminates the unreliability of pivotable joints while maintaining the ability to accommodate different bottle sizes through linear adjustment, improving reliability without sacrificing adaptability.
3Reliability
If a clamping slide preloaded with a spring is used, then storage bottles of different sizes can be securely locked, but the structure becomes more complex
Solution Approach 1:
The spring-preloaded clamping slide automatically adjusts and secures bottles of different sizes without requiring manual adjustment or complex control mechanisms. The spring provides continuous contact force that adapts to different bottle dimensions, achieving reliable locking with a simple yet effective mechanism.
4Ease of operation
If the bottle holder is designed for one-handed operation, then ease of operation is improved, but the locking mechanism must be simplified
Solution Approach 1:
The spring-preloaded clamping slide automatically secures the bottle upon insertion, requiring no additional locking actions from the user. This self-securing mechanism enables one-handed operation while maintaining reliable locking, as the spring automatically provides the necessary clamping force without requiring complex manual intervention.
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 and secure fitting of storage bottles of different sizes, ensuring reliable attachment and compensation for manufacturing inaccuracies, facilitating one-handed operation and accommodating a range of bottle capacities from 20 ml to 1000 ml.
Implementation Method 1
a spring (3) and a clamping slide (4), which is linearly displaceable in the shaft (9) and on which the spring (3) is prestressed in the clamping direction
Implementation Method 2
the two arms are pressed apart and, due to the spring effect, hold the bottleneck
Implementation Method 3
The locking mechanism fixes the cocking slide in the first position in the shaft in that the spring-loaded lug snaps into place on the stop surface and thereby limits the linear displacement of the cocking slide prestressed by the spring

AI summary
The invention relates to a bottle holder for an injection or infusion device, comprising a base body (2) which has at least one bottle receptacle (5a) for receiving the neck of a supply bottle. To enable the simplest and quickest possible loading of the injection device with supply bottles of different sizes and to securely hold the supply bottles in the bottle holder, a shaft (9) is provided in the base body (2) in which a spring-loaded clamping slide (4) is linearly displaceable. In a first position, the clamping slide (4) locks the neck of the supply bottle, and in a second position, the neck of the supply bottle is released.
