Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current postoperative care devices for periocular procedures are inadequate in reducing bruising and swelling, as they often apply excessive pressure, leading to skin necrosis, increased intraocular pressure, and limited ability to decompress the orbit, which can result in vision loss and discomfort for patients undergoing bilateral treatments.

Innovation Solution

A bilateral compression device with a central cavity and circumscribing sidewall that applies adjustable, low-pressure compression to the periocular region, featuring a micro-adjustment mechanism and a post-operative pillow with an IFD-reducing membrane to allow for forward eye movement and minimize pressure on the eyeball, while providing cooling and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional compression devices apply pressure to the periocular region, then bruising and swelling are reduced, but excessive pressure causes skin necrosis and increased intraocular pressure

Engineering Contradiction:

Improveeffectiveness in reducing bruising and swellingVSAvoidskin necrosis and intraocular pressure increases

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device applies different pressure characteristics to different regions: the central cavity provides low pressure to protect the eyeball, while the circumscribing sidewall provides higher compression to the periocular tissues for reducing swelling. This local differentiation resolves the contradiction between effective compression and preventing eye damage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The compression device is divided into functionally distinct segments: a central cavity for eye protection and a circumscribing sidewall for tissue compression. This segmentation allows each part to exert appropriate pressure levels, preventing both insufficient compression and excessive pressure on the eye.

Inventive Principle:

Principle #1Segmentation

2Reliability

If compression devices apply pressure to the orbit, then swelling is reduced, but the ability to decompress the orbit is limited

Engineering Contradiction:

Improveswelling reductionVSAvoidlimited orbital decompression capability

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The device allows dynamic adjustment of compression pressure through the micro-adjustment mechanism, enabling the pressure to be optimized for swelling reduction while maintaining the ability to decompress the orbit when needed. The flexible design permits adaptive pressure application.

Inventive Principle:

Principle #15Dynamics

3Temperature

If ice compresses are applied frequently, then cooling effect is achieved, but bleeding time increases and clotting is slowed

Engineering Contradiction:

Improvecooling effectVSAvoidbleeding time and clotting rate

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The patent replaces the thermal mechanism of ice compresses with a mechanical compression mechanism. The compression device uses physical pressure to reduce swelling and bruising without the vasoconstrictive effects of cold, thereby avoiding the prolongation of bleeding time while still achieving the desired therapeutic effect.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Device complexity

If a unilateral compression device is used, then simplicity is maintained, but it cannot accommodate bilateral procedures

Engineering Contradiction:

Improvedevice simplicityVSAvoidadaptability to bilateral procedures

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The compression device is designed with bilateral symmetry and adjustable features, allowing it to accommodate both unilateral and bilateral procedures. The micro-adjustment mechanism enables customization for different treatment scenarios, making the device universally applicable across various surgical cases.

Inventive Principle:

Principle #6Universality (Multi-functionality)
