Solution Overview

Problem

Existing cervical or lumbar traction devices fail to account for individual body differences, leading to discomfort and potential secondary injuries due to incompatibility. These devices often require multiple tools and longer times to effectively stretch multiple areas of the human body, and they necessitate professional operation, making rehabilitation time-consuming and costly.

Innovation Solution

A human traction device with ergonomically designed components made of elastic materials, allowing for adjustable positions and opening degrees to fit the user's body shape. The device features multiple movable bed board sections and counteracting force stoppers for effective linear traction of cervical, thoracic, lumbar, and pelvis-lower limb regions, enabling comfortable and safe stretching without extensive training.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing traction devices are used, then specific parts of the body can be stretched, but multiple areas require more than twice the time and different tools

Engineering Contradiction:

Improverehabilitation timeVSAvoidcoverage of body areas

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The bed board is divided into multiple independently movable sections (first bed board section, second bed board section, third bed board section, fourth bed board section), each capable of providing traction to different body regions. This segmentation allows simultaneous treatment of multiple areas without requiring separate devices or excessive time.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The traction device is designed to provide linear traction to multiple body areas (cervical, thoracic, lumbar spine, and pelvis-lower limb regions) using a single integrated system. The multiple bed board sections with stoppers can be configured to treat different regions, making the device universal for various rehabilitation needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If existing traction devices are used, then specific body parts can be treated, but the structure is complex and requires professional operation

Engineering Contradiction:

Improveuser-friendlinessVSAvoidstructural complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The bed board sections are designed to be movable along slide rails, allowing users to adjust the position and configuration of the device according to their body shape and rehabilitation needs. This dynamic adjustability simplifies operation while maintaining effectiveness, as users can easily reposition sections rather than dealing with complex fixed structures.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device allows adjustment of parameters such as the position of bed board sections, the opening degree of stoppers, and the configuration of elastic materials to fit different body types and rehabilitation requirements. This parameter adjustability makes the device easier to operate for different users without requiring extensive professional training.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If existing traction devices are used, then traction can be applied, but comfort is insufficient and secondary injuries may occur

Engineering Contradiction:

Improvesafety during tractionVSAvoiduser comfort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Elastic materials are used in the head fixing device, shoulder stoppers, armpit stopper shafts, and iliac stoppers to provide flexibility and adaptability to the user's body shape. This flexibility ensures comfortable contact and distribution of traction forces, reducing the risk of secondary injuries while maintaining reliability.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The device incorporates elastic materials and adjustable components that can be configured beforehand to accommodate different body types and prevent discomfort or injury during traction. The elastic materials act as cushioning elements that adapt to the user's anatomy, reducing pressure points and potential for secondary injuries.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Adaptability or versatility

If existing traction devices are used, then single-area traction is provided, but multiple areas require different tools

Engineering Contradiction:

Improvenumber of body areas treatedVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple functional components (bed board sections, stoppers, elastic materials) are merged into a single integrated traction device that can treat multiple body areas. The first, second, third, and fourth bed board sections work together as one system, eliminating the need for separate devices for different body regions.

Inventive Principle:

Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device provides effective linear traction to multiple areas of the body, improving comfort and preventing secondary injuries. It reduces the time and cost of traditional rehabilitation by allowing easy operation for both professionals and users, effectively treating tissue adhesions, nerve root compression, and spinal issues.
