Solution Overview
Problem
Existing temperature control devices for vehicle bodies in the automotive industry face inefficiencies due to dissimilar thermal capacities across different regions, leading to extended cycle times and potential overheating, especially when dealing with complex vehicle structures and temperature-sensitive materials.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single full-space temperature control system is used to heat the entire vehicle body uniformly, then the overall temperature control is simplified, but regions with high thermal capacity (mass-rich regions) cannot be dried efficiently and require extended cycle times
Solution Approach 1:
The temperature control system is segmented into a full-space temperature control installation for overall heating and multiple local temperature control installations for targeted heating of specific regions. This segmentation allows different regions of the vehicle body to be heated according to their specific thermal capacity requirements, thereby reducing the overall drying cycle time without increasing system complexity
Solution Approach 2:
Local temperature control installations are positioned at specific locations (such as mass-rich regions) to provide targeted heating where needed. This local quality approach ensures that regions with high thermal capacity receive additional heating attention, improving drying efficiency without requiring the entire system to operate at maximum capacity for extended periods
2Reliability
If the drying cycle time is extended to accommodate mass-rich regions, then all regions can be dried thoroughly, but temperature-sensitive materials and adhesive bonding areas are exposed to prolonged heat causing potential damage
Solution Approach 1:
Local temperature control installations are strategically positioned to target only mass-rich regions that require extended heating, while temperature-sensitive materials and adhesive bonding areas are excluded from this localized heating. This selective approach ensures complete drying of difficult-to-reach regions without subjecting sensitive components to prolonged thermal exposure
Solution Approach 2:
The temperature control system is divided into full-space and local control zones, allowing independent control of heating parameters in different regions. This segmentation enables the system to apply extended heating only where necessary while maintaining shorter exposure times for sensitive areas, thereby ensuring drying completeness without causing thermal damage
3Productivity
If local temperature control installations are added to address specific regions, then drying efficiency is improved, but the installation space and system complexity increase
Solution Approach 1:
Local temperature control installations are implemented only at specific strategic locations where mass-rich regions require targeted heating, rather than distributing control installations throughout the entire drying chamber. This selective placement improves drying efficiency for critical regions while minimizing the overall installation space and system complexity
Solution Approach 2:
The temperature control system is segmented into a primary full-space control installation and supplementary local control installations. This segmentation allows the system to maintain a simple overall structure while adding targeted heating capability only where necessary, thereby improving drying efficiency without proportionally increasing system complexity
