Solution Overview

Problem

Conventional dental treatments require multiple personnel due to the need for various dental medical devices, increasing labor costs and complicating the treatment space, making it difficult for a single doctor to perform procedures efficiently.

Innovation Solution

A holding device for dental medical devices that includes a headrest installed on a dental chair, with a medical device holder connected via rod adjusters, allowing multiple devices to be attached without additional assistance, and adaptable to different chair types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple dental medical devices are used during dental treatment, then the quality and completeness of treatment is improved, but the number of personnel required increases and labor cost increases

Engineering Contradiction:
Improvetreatment qualityVSAvoidlabor cost
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The dental chair system provides self-service functionality by automatically holding and managing multiple dental medical devices through integrated holders and arms, eliminating the need for additional personnel to manually manage these devices during treatment procedures

Inventive Principle:
Principle #25Self-service

2Reliability

If multiple dental medical devices are used during dental treatment, then the completeness of treatment is improved, but the treatment space becomes more complex and difficult to manage

Engineering Contradiction:
Improvetreatment completenessVSAvoidtreatment space complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The dental chair is designed with multi-functional integrated device holders and positioning arms that can accommodate various types of dental medical devices (suction devices, retractor devices, mirrors, etc.), allowing a single chair system to manage multiple devices without requiring additional personnel or complex spatial arrangements

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

Solution Approach 2:

Multiple device holding functions are merged into the dental chair structure itself, combining the chair's positioning capability with device support functions, thereby simplifying the overall treatment space configuration while maintaining the ability to use multiple devices simultaneously

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If existing dental chairs are modified to accommodate multiple devices, then device integration is improved, but replacement cost increases

Engineering Contradiction:
Improvedevice integrationVSAvoidmodification cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The device holder system is designed with universal adaptability to work with various types of dental medical devices and can be integrated into existing dental chair models without requiring complete chair replacement, thereby maintaining cost-effectiveness while achieving multi-device functionality

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