Solution Overview

Problem

Conventional air conditioner front panel opening and closing structures have poor durability, require professional knowledge, and pose user safety risks due to potential panel falling and exposure of internal components.

Innovation Solution

A cam assembly with a cam and panel assembly that allows easy detachment of the front panel from the main body using a lifting structure, incorporating upper and lower hooks, magnetic forces, and a cam friction pad to ensure safe and secure operation, preventing accidental fan activation when the panel is separated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional hinge structure is used to open and close the front panel, then the panel can be opened and closed, but the durability is poor and it is difficult to replace

Engineering Contradiction:
ImprovedurabilityVSAvoidopening and closing structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The opening and closing structure is divided into independent components: a cam mechanism with cam lobes and cam followers, upper and lower hooks, and a panel assembly. This segmentation allows each component to perform its specific function independently, improving durability and ease of replacement while maintaining the overall functionality of the opening and closing system.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If professional knowledge is required to open and close the front panel, then the operation can be controlled, but service costs increase

Engineering Contradiction:
Improvepanel opening and closingVSAvoidservice cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The cam mechanism is designed to be manually operable by users without requiring professional knowledge. The cam lobes and followers automatically engage and disengage the panel assembly from the main body through simple rotational motion, enabling users to perform opening and closing operations themselves, thereby reducing service costs while maintaining controlled operation.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the front panel is directly opened or closed by a user, then the operation is simple, but user product liability may occur due to panel falling

Engineering Contradiction:
Improveuser operationVSAvoiduser safety
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cam mechanism incorporates safety features that prevent panel falling before it can cause harm. The cam followers are designed to maintain continuous contact with the cam lobes throughout the rotation, ensuring the panel assembly remains securely supported during the entire opening and closing process. This prior cushioning eliminates the risk of panel dropping and associated user injuries.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Ease of repair

If the panel assembly is separated from the main body, then the panel can be removed for cleaning or repair, but the fan may become exposed and activate accidentally

Engineering Contradiction:
Improvepanel removalVSAvoidfan exposure
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The cam mechanism is designed so that the panel assembly must be completely detached from the main body before the fan can be exposed. The cam followers maintain engagement with the cam lobes until the final stage of removal, preventing accidental fan activation during the separation process. This preliminary anti-action ensures safe panel removal for cleaning or repair while preventing harmful fan exposure.

Inventive Principle:
Principle #9Preliminary anti-action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution enables easy and safe separation of the front panel, enhances durability, and prevents user safety accidents by ensuring the panel remains secure and the fan stops when the panel is removed, thus reducing service costs and improving user safety.
