The demand for reliable, user-friendly autoinjectors continues to grow. These devices must ensure safe, consistent performance for users, including those with limited dexterity. A leading pharmaceutical client approached Sanner to help develop a critical mechanism within their next-generation autoinjector that safely and reliably removes the syringe\u2019s rigid needle shield (RNS) just before use.<\/p>\n

The challenge<\/strong><\/p>\n

The client\u2019s autoinjector design required a scalable precision-engineered component to facilitate effective and safe function. This part needed to:<\/p>\n

    \n
  • Function reliably across multiple device variants, use scenarios and user abilities<\/li>\n
  • Be manufacturable at scale without compromising accuracy or performance<\/li>\n
  • Integrate seamlessly with the existing design and assembly constraints of the autoinjector<\/li>\n<\/ul>\n

    The complexity lay in achieving repeatable mechanical performance within a confined and already defined space, achieving tight tolerances in production, and ensuring the device cap could still be easily removed by users.<\/p>\n

    Our approach<\/strong><\/p>\n

    Sanner applied a combination of engineering expertise, rapid prototyping, and industry collaboration to accelerate the development of this critical component.<\/p>\n

      \n
    1. Understanding Functional Requirements<\/strong>
      \nOur team began by mapping the exact sequence of mechanical actions during device operation – from cap removal to injection initiation – identifying where the component played a key functional role.<\/li>\n
    2. Leveraging Industry Expertise<\/strong>
      \nBy engaging trusted industry contacts in medical device manufacturing, we were able to identify the most appropriate materials, forming processes, and tolerance control methods early in development.<\/li>\n
    3. Rapid Prototyping and Iteration<\/strong>
      \nWe developed bespoke prototyping techniques that allowed for quick iteration cycles. Each prototype was evaluated for reliability, manufacturability, and ease of operation, leading to incremental refinements and performance improvements.<\/li>\n
    4. User-Centric Testing<\/strong>
      \nPrototypes were assessed with the end user in mind that even individuals with limited dexterity could operate the mechanism comfortably and confidently.<\/li>\n<\/ol>\n

      The outcome<\/strong><\/p>\n

      We were able to deliver a robust and manufacturable design that met all functional and regulatory requirements. The resulting mechanism consistently removed the RNS with high reliability, supporting the overall usability and safety of the device.<\/p>\n

      Sanner\u2019s collaborative and technical approach enabled the client to move forward confidently into detailed design and verification stages significantly reducing both development time and technical risk.<\/p>\n <\/div>\n <\/div>\n <\/div>\n<\/section>","protected":false},"featured_media":5791,"template":"","blog_category":[75],"class_list":["post-6006","blog","type-blog","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\nUsing Prototypes to Accelerate Autoinjector Innovation -
