Solution Overview

Problem

Conventional painting booths with elevated robot guide rails face challenges such as limited space for control areas, air flow obstruction, and high construction costs due to the need for stable side walls without crossbeams.

Innovation Solution

The design features sloping side walls at the upper control area to create more space for control devices and personnel, while maintaining a wider flow cross-section for air distribution, and uses separate support structures for elevated guide rails to reduce the load on side walls, allowing for a more efficient and cost-effective layout.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If guide rails are mounted elevated above the conveyor, then robot freedom of movement is improved and air flow obstruction is reduced, but space for control areas is limited and construction costs increase

Engineering Contradiction:
Improverobot freedom of movementVSAvoidspace for control areas
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent transitions from horizontal control area placement to vertical placement by utilizing the elevated space above the conveyor. Control areas are positioned on the upper side walls at elevated levels, creating a three-dimensional layout that resolves the space conflict between control areas and air flow paths.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The control areas are segmented and distributed at different vertical levels rather than concentrated at a single level. The upper control area is separated from the lower control area, allowing independent optimization of each zone for its specific function while maintaining overall system efficiency.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If side walls are made wider to provide space for control areas, then control area space is improved, but air flow path is narrowed and construction costs increase

Engineering Contradiction:
Improvespace for control areasVSAvoidair flow distribution
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The patent moves control areas from the horizontal plane to the vertical plane by positioning them on upper side walls. This vertical arrangement allows control areas to be accommodated without increasing the horizontal width of the booth, thereby preserving the air flow cross-section.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The side walls are designed with different properties at different heights. The upper portion of the side walls contains control areas while maintaining sufficient width for air flow, creating a localized optimization where control functionality and air flow requirements are simultaneously satisfied through vertical zonation.

Inventive Principle:
Principle #3Local quality

3Stability of the object's composition

If side walls are made more stable to support elevated guide rails, then guide rail stability is improved, but construction costs increase

Engineering Contradiction:
Improveguide rail stabilityVSAvoidconstruction costs
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent extracts the support function from the side walls by introducing separate support structures. These independent support elements carry the guide rails, allowing the side walls to be designed with minimal thickness and without crossbeams, thereby reducing construction costs while maintaining stability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Separate support structures act as intermediary elements between the guide rails and the side walls. These support structures absorb and transmit the loads, allowing the side walls to remain thin and cost-effective while still providing stable mounting for the elevated guide rails.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Coating zones with elevated guide rails (10) for coating and/or handling robots (11), arranged above the application objects (2) where appropriate, have walkable control areas (15, 17) arranged one above the other on the outer side walls. The side wall (6) slopes inwards at the upper control area (17), which houses control and supply units for the robots on the elevated guide rails. The support structures (12) for the elevated guide rails (10) are supported on or below the floor level (7) or on the ceiling wall (5) by support elements (14) extending transversely to the transport path of the application objects.
