Medical Measurement Apparatus Hook Positioning for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diagnostic ultrasound apparatuses used independently and upright are prone to falling due to the force exerted by the movement of the probe, compromising safety during operation.
Innovation Solution
A medical measurement apparatus with a vertically long apparatus body and a hook positioned below the center of gravity to securely hold the cable, preventing the apparatus from falling by distributing the load effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the diagnostic ultrasound apparatus body is made compact and slim with vertical orientation for independent use, then the apparatus can be used independently and upright, but the apparatus body is pulled through the cable due to probe movement and may fall
Solution Approach 1:
The cable is hooked to the handle of the cart through an opening with which the center of the handle of the cart is provided, in advance before probe operation begins. This preliminary action prevents the cable from getting entangled or caught in the caster during subsequent probe movement, resolving the stability issue while maintaining independent use capability
2Ease of operation
If the cable is hooked to the handle of the cart through the center opening, then the probe can be used while preventing cable entanglement, but the apparatus body is still pulled and may fall when used independently
Solution Approach 1:
The weight of the apparatus body is taken into consideration when positioning the hook. The hook is placed at a specific position that utilizes the apparatus body's weight as a counterbalancing force to resist the pulling force from cable tension, preventing the apparatus from falling while maintaining ease of operation
3Reliability
If the hook is positioned to hold the cable securely, then the apparatus body stability is improved, but the hook position must be precisely determined relative to center of gravity
Solution Approach 1:
The hook is positioned at a specific local region of the apparatus body where the gravitational moment and cable tension moment can be effectively balanced. This localized positioning optimization ensures stability without requiring complex positioning mechanisms, resolving the contradiction between reliability and device complexity

AI summary
A medical measurement apparatus includes: a cable connected to a probe; an apparatus body from which the cable is led out, the apparatus body having a bottom face and a side face larger than the bottom face, and being vertically long in shape in use; and a hook disposed on the apparatus body, the hook being lower than a position of a center of gravity of the apparatus body, the hook holding the cable by hooking.
