Injector Testing Grips With Angled Alignment and Secure Gripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional injection needle testing systems struggle to easily interface with injectors due to their varying geometries, limiting effective alignment and secure gripping during testing.
Innovation Solution
The development of grips for injection testing systems that include angled alignment and gripping portions, along with slip-resistant coatings and customizable profiles, allowing secure alignment and gripping of injectors with asymmetric or symmetric geometries, including cylindrical, elliptical, or semi-square shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional grips are used for injection testing systems, then the device complexity is reduced, but the adaptability to various injector geometries deteriorates
Solution Approach 1:
The grip is designed with multiple functional sections (alignment section with angled surface, gripping section with textured surface, and support section) that can accommodate various injector geometries including asymmetric and symmetric shapes. This multi-functional design allows a single grip structure to handle different injector types, achieving universality without requiring multiple specialized grips for each geometry type.
Solution Approach 2:
The grip is divided into distinct functional sections: an alignment section with an angled alignment surface for positioning, a gripping section with a textured gripping surface for secure holding, and a support section. This segmentation allows each part to perform its specific function optimally while working together to handle various injector geometries effectively.
2Reliability
If conventional gripping surfaces are used, then the ease of manufacture is improved, but the gripping reliability deteriorates due to slipping
Solution Approach 1:
The gripping surface is provided with a textured pattern only in the gripping section, while other sections maintain smooth surfaces. This localized texturing increases friction and prevents slipping where needed without requiring complex manufacturing throughout the entire grip structure, thus improving gripping reliability while maintaining ease of manufacture.
3Measurement precision
If simple alignment mechanisms are used, then the device complexity is reduced, but the measurement precision deteriorates due to misalignment
Solution Approach 1:
The alignment section features an angled alignment surface that creates a unique geometric relationship between the grip and injector. This asymmetric angular configuration provides precise alignment guidance for injectors with varying geometries, ensuring accurate positioning without requiring complex adjustable alignment mechanisms.

AI summary
An example injection needle positioner includes: a first grip comprising a first grip face on a first lateral side of the first grip; and a second grip, comprising: a second grip face on a first lateral side of the second grip, the second grip face facing the first grip face, the second grip face comprising: a first section that extends from a first end of the second grip and comprises a first profile configured to align an injector; and a second section located toward a second end of the first grip, relative to the first section, and having a second profile configured to securably grip the injector in cooperation with the first grip face.
