Solution Overview

Problem

The existing duct-type heat exchanger systems face difficulties in mounting and remounting the heat exchanger due to its heavy and delicate nature, often resulting in misalignment and potential damage during servicing, especially when mounted in false ceilings or walls.

Innovation Solution

The duct-type heat exchanger system incorporates housing and heat exchanger stop members that are releasably attachable, along with guide members that align and guide each other during translation, ensuring proper positioning and limiting movement to prevent damage, thereby facilitating easier and accurate mounting and remounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the heat exchanger is removed from the housing for servicing, then maintenance can be performed on the heat exchanger, but positioning the heat exchanger relative to the housing during remounting becomes difficult and may cause damage

Engineering Contradiction:
Improvemaintenance capabilityVSAvoidremounting difficulty
Core Design Contradiction:
Ease of repairVSEase of operation

Solution Approach 1:

The housing guide member and heat exchanger guide member are positioned in advance to define a translation path. This preliminary arrangement ensures that when the heat exchanger is reinserted, it automatically follows the correct path and aligns with the housing, eliminating positioning difficulties during remounting.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The guide members act as intermediary elements between the heat exchanger and housing. They facilitate the interaction by providing a physical pathway that guides the heat exchanger stop member into alignment with the housing stop member, making the remounting process easier and safer.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the heat exchanger is handled during remounting, then it can be reinstalled in the housing, but the heavy and delicate nature of the component increases the risk of misalignment and damage

Engineering Contradiction:
Improvereinstallation capabilityVSAvoidrisk of damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The guide members enable the heat exchanger to guide itself into the correct position during reinstallation. The heat exchanger stop member follows the path defined by the guide members and automatically aligns with the housing stop member, reducing the need for manual positioning and minimizing the risk of damage during handling.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The guide members serve as intermediary structures that protect the delicate heat exchanger components during handling. By providing a predefined translation path, they prevent misalignment and reduce the force required for positioning, thereby lowering the risk of damage to the heavy and delicate component.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the housing is permanently mounted in a false ceiling or wall, then the housing remains stable and secure, but the heat exchanger cannot be easily removed or repositioned

Engineering Contradiction:
Improvehousing stabilityVSAvoidheat exchanger accessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The system is segmented into two distinct components: the permanently mounted housing and the removable heat exchanger. The guide members and stop members are designed as separate elements that facilitate the separation and reassembly of these components, allowing the heat exchanger to be easily removed and reinstalled while the housing remains stable and secure in its permanent location.

Inventive Principle:
Principle #1Segmentation

AI summary

There is provided a duct-type heat exchanger system. The duct-type heat exchanger system comprises a housing and a heat exchanger. The housing comprises a housing stop member and a housing guide member. The heat exchanger comprises a heat exchanger stop member and a heat exchanger guide member. The housing is configured such that the heat exchanger is at least partially insertable into the housing by a translation in a first direction of the heat exchanger relative to the housing. The housing stop member and the heat exchanger stop member are configured to be releasably attachable to each other. The housing guide member and the heat exchanger guide member are configured to guide the heat exchanger stop member and the housing stop member into alignment with each other as the heat exchanger is translated in the first direction relative to the housing.
