Solution Overview

Problem

Medical supply units in intensive care and surgery require flexible and secure attachment options for medical devices, but existing solutions necessitate tool-use for adjustments, leading to hygiene issues due to overhanging cables and limited mobility.

Innovation Solution

A medical supply unit with a carrier featuring a hollow rail and conductor rails, including a positioning rail and a locking mechanism that allows adapters to be securely attached and adjusted manually without tools, ensuring ergonomic positioning and improved hygiene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adapters are secured using screws and sliding blocks in T-slots, then secure attachment is achieved, but tool-use is required for adjustments

Engineering Contradiction:
Improvesecure attachmentVSAvoidadjustment convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the screw-based mechanical fastening system with a spring-loaded clamping mechanism. The spring element automatically applies clamping force when the adapter is inserted, eliminating the need for screws and tools while maintaining secure attachment through elastic mechanical action.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The spring-loaded clamping mechanism is designed to automatically engage and secure the adapter upon insertion without requiring manual intervention for fastening. The system serves itself by using the insertion motion to compress the spring, which then automatically applies the clamping force to hold the adapter in place.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If control elements are relocated to improve ergonomics, then ease of operation is improved, but cable management and hygiene deteriorate

Engineering Contradiction:
Improveergonomic positioningVSAvoidhygiene conditions
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent changes the positioning parameter of control elements by making them height-adjustable along the vertical rail. This allows the control panel to be positioned at optimal ergonomic heights while keeping cables contained within the structured system, preventing them from overhanging and compromising hygiene.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The vertical rail system serves multiple functions: it provides structural support, enables height adjustment for ergonomic positioning, and acts as a cable management conduit. This multi-functionality allows ergonomic optimization without creating hygiene issues from exposed cables.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If fixed platforms are used for medical devices, then stability is improved, but flexibility and mobility are reduced

Engineering Contradiction:
Improvedevice stabilityVSAvoidconfiguration flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent transitions from fixed platforms to a dynamic system where adapters can be easily repositioned along the vertical rail. The spring-loaded clamping mechanism allows adapters to be quickly removed and repositioned to different heights, providing configurability while maintaining stability during use through secure clamping.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system segments the medical supply unit into modular components (adapters, control panels, devices) that can be independently positioned and reconfigured along the vertical rail. This segmentation enables flexible arrangement while each component maintains its own stability through the clamping mechanism.

Inventive Principle:
Principle #1Segmentation
