Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automobile air conditioners face challenges in efficiently controlling internal temperatures due to the inability to adjust the amount of cooling water in the heater core, leading to suboptimal cooling and heating efficiency and space constraints within the engine room.
Innovation Solution
A heater core with a flow rate adjusting mechanism, comprising a ball valve and bypass line, allows precise control of cooling water flow based on user-set temperatures, eliminating the need for a separate temp door and optimizing space usage by interlocking with a sub-door to enhance airflow and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a temp door is used to control opening degree of cool air passage and warm air passage, then temperature control function is achieved, but device complexity increases and space occupation increases
Solution Approach 1:
The patent combines the temperature control function with the existing sub-door mechanism. The sub-door is configured to selectively block the warm air passage, thereby controlling the mixing of cool and warm air without requiring a separate temp door. This merging of functions reduces device complexity while maintaining temperature control capability.
Solution Approach 2:
The sub-door is designed to serve multiple functions: it controls the opening degree of the cool air passage and simultaneously controls the warm air passage by selective blocking. This multi-functionality eliminates the need for a dedicated temp door, reducing overall device complexity while achieving comprehensive temperature control.
2Adaptability or versatility
If a temp door is used to control air passages, then temperature control is achieved, but space in engine room is occupied
Solution Approach 1:
The patent merges the temperature control function into the existing sub-door mechanism, eliminating the need for a separate temp door component. This consolidation reduces the volume occupied in the engine room while maintaining full temperature control functionality through the sub-door's selective blocking capability.
3Productivity
If cooling water flow amount is not controlled, then heater core structure is simple, but cooling and heating efficiency is insufficient
Solution Approach 1:
The patent implements self-service temperature control by allowing the driver to directly adjust the sub-door opening degree. This manual adjustment automatically controls the mixing ratio of cool and warm air without requiring complex electronic sensors, controllers, or actuators, thereby maintaining structural simplicity while achieving efficient temperature control.
4Adaptability or versatility
If evaporator and heater core are positioned at specific places with temp door, then air cooling and heating function is achieved, but noise is generated and airflow is obstructed
Solution Approach 1:
The patent merges the temperature control function into the sub-door mechanism, eliminating the separate temp door that caused noise and airflow obstruction. The simplified air passage structure without the temp door reduces turbulence and noise generation while maintaining effective air cooling and heating functions.
