Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing osteotomy guide plates are prone to damage and inaccuracy due to the reliance on single hole sites for both guiding and fixing, leading to issues with nail hole positioning and drainage, which can result in surgical errors and reduced success rates.

Innovation Solution

The osteotomy guide plate is designed with standardized components, including a guide plate retention hole and a nail hole with a standardized sleeve, allowing for adjustable and durable construction, and a detachable protective inner sleeve for enhanced strength and accuracy, along with a drainage channel for improved debris management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the same hole site is used for both guiding and fixing the osteotomy guide plate, then the positioning process is simplified, but the guide plate is prone to damage and positioning accuracy decreases

Engineering Contradiction:

Improvepositioning process complexityVSAvoidguide plate durability and positioning accuracy

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent divides the hole site into two separate functional components: a guide plate retention hole for fixing the guide plate to the bone, and a nail hole with standardized sleeve for guiding the drilling direction. This segmentation allows each hole to perform its specific function independently, preventing the guide plate from being damaged while maintaining positioning accuracy.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If no drainage hole is provided in the guide plate, then the guide plate structure is simpler, but drilling debris can damage the guide plate and increase surgical risk

Engineering Contradiction:

Improveguide plate structure complexityVSAvoiddrilling debris damage risk

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a drainage channel as an intermediary structure that allows drilling debris to be evacuated from the guide plate interior during the surgical procedure. This drainage channel prevents debris accumulation and potential damage to the guide plate while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If a drainage hole is provided under the guide plate retention hole, then debris can be drained, but the drainage hole aperture is limited and easily blocked

Engineering Contradiction:

Improvedebris drainage capabilityVSAvoiddrainage hole aperture and blockage resistance

Core Design Contradiction:

Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent transitions from a single-point drainage hole to a multi-dimensional drainage channel system that extends through the guide plate structure. This channel-based approach provides a larger effective drainage cross-section and multiple evacuation paths, reducing the likelihood of blockage while improving debris removal efficiency.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Ease of operation

If physical markers are used for nail hole positioning, then the positioning process is traditional and familiar, but positioning accuracy decreases due to marker displacement and scanning artifacts

Engineering Contradiction:

Improvepositioning operation familiarityVSAvoidnail hole positioning accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical positioning system (physical markers, gauge pins, and manual scanning) with a digital model-based system. The standardized sleeve and nail hole are directly defined in the 3D printed guide plate according to preoperative planning, eliminating marker displacement and scanning artifact issues while maintaining ease of surgical execution.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
