Solution Overview

Problem

Ceiling type air conditioners often concentrate discharged air into specific areas, leading to uneven air distribution and potential discomfort or health issues, and existing wind guide devices have complex structures that can be unsafe and difficult to install, with potential durability and aesthetic concerns.

Innovation Solution

A detachable wind-visor is integrated into the air conditioner's front panel, featuring a coupling part and guide part to direct air away from the suction hole, using magnets for secure attachment and a lightweight design to prevent air concentration and enhance safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a cover is used to cover the discharge hole, then foreign substances are prevented from entering the air conditioner, but the cover cannot uniformly discharge air in various directions causing air concentration in specific positions

Engineering Contradiction:
Improveforeign substance preventionVSAvoidair discharge uniformity
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The cover is divided into multiple discharge holes instead of a single opening, allowing air to be discharged uniformly in various directions while still preventing foreign substances from entering when closed

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover is made rotatable to dynamically adjust the discharge direction of air, enabling uniform distribution of conditioned air throughout the indoor space rather than concentrating it in specific positions

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a wind guide device with multiple components is used, then air discharge direction can be controlled, but the structure becomes complex and components may fall down causing safety accidents

Engineering Contradiction:
Improveair discharge direction controlVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wind guide device is integrated with the cover as a single unified structure rather than separate components, simplifying the overall structure while maintaining the ability to control air discharge direction through rotation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated cover-wind guide structure serves multiple functions: preventing foreign substance entry when closed, controlling air discharge direction when open, and guiding air flow patterns, eliminating the need for separate safety fixation mechanisms

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If components are strongly fixed using screws or adhesion material, then components are prevented from falling down, but attachment and detachment become difficult and punched holes remain deteriorating the exterior

Engineering Contradiction:
Improvecomponent stabilityVSAvoidattachment and detachment ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mechanical fastening system (screws or adhesion material) is replaced with a magnetic field-based fixation system, allowing the wind guide device to be securely held while enabling easy attachment and detachment without leaving permanent marks or requiring punched holes

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
