Vehicle Air Conditioner Cable Fixing Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners for vehicles using cable connecting devices face issues such as damage, loss, and increased conveyance costs due to weak joining power, and require additional protective structures during delivery and assembly.
Innovation Solution
An air conditioner design that integrates a cable fixing part with the air-conditioning case, reducing the need for additional protective measures and enhancing the joining strength, allowing for easier detachment and reattachment during assembly and delivery, while minimizing weight and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable connecting device is mounted on the air-conditioning case, then the door can be operated remotely, but the joining power is weak causing damage or loss during conveyance
Solution Approach 1:
The cable connecting device is separated into two functional parts: a mounting structure attached to the air-conditioning case and a cable reel assembly that can be independently mounted and removed. This segmentation allows the cable connecting function to be preserved while enabling flexible installation and removal without damaging the air-conditioning case.
Solution Approach 2:
The mounting structure is pre-installed on the air-conditioning case during manufacturing, preparing the foundation for later attachment of the cable reel assembly. This preliminary action ensures that when the cable connecting device is needed, it can be quickly and securely attached without requiring complex installation procedures.
2Reliability
If additional protective structures are added during delivery, then damage and loss are prevented, but weight and manufacturing costs increase
Solution Approach 1:
The cable connecting device transitions from a permanently mounted configuration to a removable and relocatable configuration. During delivery, the device can be removed from the air-conditioning case and temporarily stored separately or repositioned to a safer location, providing protection without adding permanent weight or structural complexity.
Solution Approach 2:
The cable connecting device can be temporarily discarded (removed) from the air-conditioning case during delivery and storage phases, then recovered and reattached when the vehicle assembly or operation phase begins. This approach eliminates the need for permanent protective structures while maintaining functionality when needed.
3Reliability
If the cable connecting device is permanently fixed, then stability is improved, but ease of assembly and disassembly is reduced
Solution Approach 1:
The cable connecting device is divided into a mounting structure and a cable reel assembly that can be independently attached and detached. This segmentation provides stable operation during use while enabling easy assembly and disassembly for manufacturing, maintenance, or relocation purposes.
Solution Approach 2:
The mounting structure is pre-installed on the air-conditioning case with attachment features (such as hooks or mounting brackets) that prepare the system for quick attachment of the cable reel assembly. This preliminary preparation enables stable operation when assembled while maintaining ease of assembly and disassembly through simple connection mechanisms.

AI summary
The present invention relates to an air conditioner for a vehicle, in which a means for fixing a cable connecting device is disposed integrally with an air-conditioning case, thereby having an optimized installation location, keeping rigidity, achieving weight lightening, and enhancing assemblability. The air conditioner is to condition air in the interior of the vehicle by heating or cooling indoor air, and includes: a cable connecting device for connecting an actuating means of a controller of the vehicle to actuate a door inside an air-conditioning case with an actuating means of the air-conditioning case by a cable; and a cable fixing part for fixing the cable connecting device to the air-conditioning case.
