Solution Overview

Problem

Current treatments for intervertebral disc-related pain, such as low back pain and neck pain, are either invasive or unsatisfactorily effective, and there is a need for a safer and more efficient method to address the pain caused by degenerating discs.

Innovation Solution

A composition comprising lactic acid or its pharmaceutically acceptable salts is administered locally into the intervertebral disc to accelerate the ageing process, transforming the disc into solid and dense connective tissue, thereby reducing pain by limiting fluid leakage and nerve growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If surgical stabilization is performed to reduce disc movement, then pain from nerve compression is reduced, but the treatment becomes invasive with associated risks

Engineering Contradiction:
Improvepain from nerve compressionVSAvoidinvasiveness of treatment
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The invention extracts the painful element (mobile disc causing nerve compression) by inducing calcification of the disc, transforming it from a mobile cartilaginous structure to a fixed bony structure, thereby eliminating the need for surgical stabilization

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the physical and chemical parameters of the disc by introducing calcium phosphate deposits through local injection, transforming the disc material from soft cartilage to hardened calcified tissue, achieving stabilization without surgery

Inventive Principle:
Principle #35Parameter changes

2Stress or pressure

If chemonucleolysis is used to dissolve the nucleus pulposus, then pressure on nerves is reduced, but the treatment does not address the underlying degeneration and may worsen disc stability

Engineering Contradiction:
Improvepressure on nervesVSAvoiddisc stability
Core Design Contradiction:
Stress or pressureVSReliability

Solution Approach 1:

Instead of dissolving the nucleus pulposus as in chemonucleolysis, the invention promotes calcification and solidification of the disc materials, reversing the degradation process by transforming soft tissue into stable bony structures that provide long-term stability

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If cell rejuvenation or regeneration is attempted, then disc function may be restored, but the nutritionally deprived environment prevents successful cell survival

Engineering Contradiction:
Improvedisc functionVSAvoidnutritional deprivation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention converts the harmful effect of nutritional deprivation and disc degeneration into a beneficial outcome by inducing controlled calcification, where the degenerative process is redirected to form stable bony structures that eliminate pain rather than attempting to reverse degeneration

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Ease of operation

If the intervertebral disc remains flexible to allow motion, then spinal mobility is maintained, but the disc may leak or herniate causing pain

Engineering Contradiction:
Improvespinal mobilityVSAvoiddisc leakage and herniation
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention changes the mechanical parameters of the disc by inducing calcification, transforming it from a flexible shock-absorbing structure to a rigid stabilizing structure, accepting reduced mobility as a trade-off for eliminating herniation and leakage

Inventive Principle:
Principle #35Parameter changes

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 treatment effectively increases the stiffness of the intervertebral disc, leading to decreased pain and improved mobility, with the added benefits of being less invasive and more cost-effective compared to existing methods.
