Integrated Housing Mount for Accurate Auxiliary Unit Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medicament delivery devices suffer from complications such as extra components detaching or falling off, leading to reduced quality of measurement and monitoring, and lack of robust and accurate positioning of auxiliary units.
Innovation Solution
A housing element with an integrated mount that securely attaches an auxiliary unit to the medicament delivery device, ensuring robust and accurate positioning, using methods like positive locking, friction-fit, magnetism, or non-permanent adhesive, allowing secure attachment and preventing incorrect unit attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate sleeve is used to attach auxiliary units to injection pens, then the auxiliary unit can be attached to the device, but the sleeve may detach or fall off during use
Solution Approach 1:
The patent integrates the mounting function directly into the housing element of the injection device, eliminating the separate sleeve component. The housing element includes an integrated mount that securely attaches the auxiliary unit, combining the housing and mounting functions into a single unified structure that prevents detachment while reducing component count.
2Measurement precision
If a separate sleeve is used for mounting, then the auxiliary unit can be attached, but the positioning accuracy and orientation are reduced
Solution Approach 1:
The housing element incorporates a specifically designed integrated mount with localized mounting features at precise positions. This mount includes orientation indicators and positioning structures that ensure the auxiliary unit is attached at the correct location and orientation, providing accurate positioning while maintaining ease of attachment through the designed interface.
3Reliability
If multiple components are used for mounting, then attachment is possible, but the device becomes more complicated and prone to dislocation
Solution Approach 1:
The patent combines the housing element and mounting structure into a single integrated unit, eliminating the need for separate sleeves and mounting components. This unified structure reduces the number of parts that can detach or become dislocated, while maintaining reliable attachment of the auxiliary unit for continuous monitoring.
