Solution Overview

Problem

Current equipment and device mounting systems for stretchers or litters lack standardization, leading to inefficiencies in configuration and relocation, often requiring specialized tools and being incompatible across different manufacturers, especially when dealing with mobile structures.

Innovation Solution

A universal, modular mounting system with a securement track and universal mounts that allow for easy reconfiguration and relocation of equipment and devices on stretchers or litters, enabling compatibility with various manufacturers' hardware without the need for custom tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If standardized mounting systems are implemented, then compatibility and ease of operation improve, but device complexity increases due to the modular track and mount design

Engineering Contradiction:
Improveease of configurationVSAvoidmounting system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mounting system employs universal mounts and a standardized track design that can accommodate multiple types of equipment and devices from different manufacturers. The track runs along the stretcher frame and accepts various mounting configurations, allowing the same base structure to serve multiple functions and兼容不同设备

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

Solution Approach 2:

The mounting system is divided into modular components including the track, universal mounts, and quick-release fasteners. This segmentation allows individual components to be independently selected, installed, and replaced based on specific needs, simplifying the overall system while maintaining versatility

Inventive Principle:
Principle #1Segmentation

2Productivity

If quick-release mounting hardware is added for faster configuration, then productivity improves, but device complexity and cost increase

Engineering Contradiction:
Improveconfiguration speedVSAvoidmounting hardware complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The quick-release mounting system is designed to be operated by end-users without requiring specialized tools or technical expertise. The fasteners can be manually engaged and disengaged through simple hand operations, allowing users to independently reconfigure equipment positions or remove devices as needed

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mounting system transitions from static permanent mounting to dynamic reconfigurable mounting. The quick-release fasteners enable the mounting state to change easily between secured and released positions, allowing the equipment to be rapidly reconfigured for different operational scenarios

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If equipment is mounted on mobile structures like stretchers, then adaptability improves, but reliability of mounting decreases due to increased forces and vibration

Engineering Contradiction:
Improvemobility adaptabilityVSAvoidmounting security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The universal mounts incorporate spherical or rounded contact surfaces that interface with the linear track, allowing for multi-directional adjustment and secure positioning. This curved geometry provides stable engagement while accommodating the dynamic forces experienced during stretcher movement and patient transport

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The mounting system combines multiple functions into integrated components: the universal mounts simultaneously provide positioning, securing, and quick-release capabilities; the track serves both as a structural support and a guidance rail for the mounting components

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A stretcher which comprises a bed, and a frame having first and second parallel frame members coupled to first and second lateral frame members is disclosed. A securement track is define by an upper surface of at least one of the first parallel frame member, the second parallel frame member, the first lateral frame member, and the second lateral frame member, the securement track having a plurality of alternating open regions and necked down regions along a length. A bed mount configured to both support the bed and be releasably secured in the securement track in a secure condition, and configured to be repositionable along the length of the securement track in an unsecured condition.
