Scanner Cover With Partial Arch Trusses For Impact Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices, particularly medical devices like bladder scanners, are susceptible to damage from impacts due to lack of robust mechanical design, leading to costly replacements when dropped.
Innovation Solution
A protective cover made from flexible, elastic polymer with a detachable cap and partial arch trusses that deflect impact forces, preventing damage to sensitive components while allowing normal operation and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cover is added to prevent impact damage, then device protection is improved, but device complexity increases
Solution Approach 1:
The protective cover is divided into a body portion and a separate cap that can be selectively attached to cover the sensor aperture. This segmentation allows the cover to provide protection while maintaining sensor accessibility when needed, resolving the contradiction between protection and functionality.
Solution Approach 2:
The cap is constructed from flexible, elastic polymer material that can deflect upon impact. This flexibility allows the cap to absorb impact forces while remaining lightweight and simple in structure, providing protection without significantly increasing device complexity.
2Reliability
If a cap covers the sensor aperture, then impact protection is improved, but sensor accessibility deteriorates
Solution Approach 1:
The cap is designed to be selectively attachable and detachable from the cover body. Users can attach the cap when protection is needed and remove it when sensor access is required, dynamically adjusting the system state to resolve the contradiction between protection and accessibility.
Solution Approach 2:
The cap specifically covers only the sensor aperture area while leaving the rest of the device body accessible. This localized protection approach provides sensor protection without interfering with other device operations or requiring complete enclosure.
3Strength
If a rigid protective structure is used, then impact resistance is improved, but flexibility and ease of cleaning deteriorate
Solution Approach 1:
The cap is made from flexible, elastic polymer material that can bend and deflect upon impact rather than breaking. This flexibility provides adequate impact protection while allowing the cap to be easily molded and manufactured, and enables thorough cleaning by allowing the material to be manipulated and dried completely.
Solution Approach 2:
The protective cover system combines the flexible polymer cap with the cover body structure, creating a composite protection system that provides impact resistance through the flexible material's ability to absorb and distribute impact forces while maintaining ease of manufacturing and cleaning.

AI summary
A protective cover (800) for a medical device includes a body (700) and a cap (100) that is selectively attachable to the body. The cap 100 includes an annulus 101 and a rounded vault (102) spanning an interior portion (118) of the annulus. The rounded vault defines a convex exterior (301). A plurality of partial arch trusses (103,104,105,106,107,108,109) extends from the annulus along the convex exterior toward an apex (601) of the convex exterior. Distal ends (613,614,615,616,617,618,619) of the plurality of partial arch trusses define an interstice (611) at the apex. The partial arch trusses provide longitudinal deflection of impact forces to protect the medical device.
