Ventilation assembly for a heat exchanger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation assemblies for car heat exchangers are prone to connector damage and dust accumulation during transportation due to the connector being disconnected from the power supply or control circuit.
Innovation Solution
A ventilation assembly with a retaining structure that includes a box-shaped formation with an open side for inserting the connector and a closed side to prevent external access, featuring a retaining member to securely hold the connector, protecting it from damage and dust ingress during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is left disconnected during transportation, then the ventilation assembly can be easily assembled and disassembled, but the connector is liable to be damaged and dust can enter and accumulate
Solution Approach 1:
The connector is nested within the retaining structure during transportation, with the retaining member providing internal protection. The engagement member of the connector fits into the retaining structure, creating a nested configuration that protects the connector while maintaining easy assembly and disassembly capabilities.
Solution Approach 2:
The retaining structure is pre-configured with the retaining member in position before transportation begins. This preliminary arrangement ensures the connector is automatically protected as soon as it is inserted into the retaining structure, preventing damage and dust accumulation during the entire transportation process.
2Ease of operation
If the connector is left exposed, then access to terminals is easy, but dust enters and accumulates in the connector
Solution Approach 1:
The retaining structure is segmented with an open side and a closed side, allowing selective access. The closed side protects the connector from dust during transportation, while the open side allows easy access when needed. The retaining member creates a barrier that segments the connector space from the external environment.
3Reliability
If a retaining structure is added to protect the connector, then connector damage and dust accumulation are prevented, but device complexity increases
Solution Approach 1:
The retaining structure serves multiple functions simultaneously: it protects the connector from physical damage, prevents dust accumulation, and provides a organized mounting location. The retaining member not only secures the connector but also defines the insertion path and maintains proper positioning, consolidating multiple protective functions into a single integrated component.
Solution Approach 2:
The retaining structure is merged with the main body of the ventilation assembly, integrating the protective function into the existing structure rather than adding a separate standalone component. This integration reduces overall complexity while maintaining the protective benefits for the connector.
