Solution Overview

Problem

Existing painting systems require a traveling device for door opening/closing and painting robots, leading to a complex and oversized paint booth structure with increased maintenance needs.

Innovation Solution

A painting system where a horizontally positioned multi-joint door opening/closing robot and a vertically positioned multi-joint painting robot are fixedly set on the paint booth's sidewalls, allowing the door to be opened and closed without a traveling device, with the robots' operating ranges overlapping to facilitate painting and maintaining the door in an open state during body transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traveling device is provided for door opening/closing and painting robots, then the robots can move to follow the transported body, but the paint booth structure becomes complicated and increased in size

Engineering Contradiction:

Improverobot mobility to follow transported bodyVSAvoidpaint booth structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the traveling device from the system. Instead of providing a traveling device to move the robots, the patent fixes the door opening/closing robot and painting robot at specific positions on the paint booth sidewalls. The robots achieve their function through posture changes and overlapping operating ranges rather than movement, thereby removing the complex traveling device structure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of moving the robots to follow the transported body (conventional approach), the invention inverts the approach by fixing the robots and having them adjust their postures to maintain operation. The door opening/closing robot and painting robot are fixed at different heights on the sidewalls and change their postures to follow the body transport, eliminating the need for a traveling device.

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If a traveling device is provided for door opening/closing and painting robots, then the robots can move to follow the transported body, but the paint booth size is increased

Engineering Contradiction:

Improverobot mobility to follow transported bodyVSAvoidpaint booth size

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

Principle #13The other way round (Inversion)

3Adaptability or versatility

If a traveling device is provided for door opening/closing and painting robots, then the robots can move to follow the transported body, but maintenance of the traveling device is required

Engineering Contradiction:

Improverobot mobility to follow transported bodyVSAvoidmaintenance requirement

Core Design Contradiction:

Adaptability or versatilityVSEase of repair

Solution Approach 1:

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Inventive Principle:

Principle #13The other way round (Inversion)

4Adaptability or versatility

If separate door opening/closing robot and painting robot are provided, then dedicated functions are achieved, but both robots must be capable of traveling which complicates the structure

Engineering Contradiction:

Improvededicated robot functionsVSAvoidrobot traveling capability

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the traveling capability requirement from both robots. The door opening/closing robot and painting robot are fixed at specific positions on the paint booth sidewalls and perform their dedicated functions through posture changes rather than movement. This maintains their specialized functions while removing the complex traveling capability requirement.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of providing traveling capability to both robots (conventional approach), the invention inverts the approach by fixing both robots at different heights on the sidewalls. The door opening/closing robot and painting robot change their postures to follow the body transport, eliminating the need for traveling capability while maintaining dedicated functions.

Inventive Principle:

Principle #13The other way round (Inversion)
