Sliding Door Support Layout to Prevent Air Conditioner Rattle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air conditioning device designs with sliding doors suffer from low design flexibility and generate abnormal rattling sounds due to the restricted layout and placement of door support sections within the guide groove, particularly when these sections are located in the groove lacking section.
Innovation Solution
The air conditioning device employs specific relational expressions to position door support sections, ensuring that the distance from the door tip to the adjacent support section and the distance between support sections on either side of the groove lacking section are optimized, thereby preventing abnormal rattling sounds by ensuring proper support and alignment within the guide groove.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insertion opening is provided at the end of the guide groove in the first case section and closed by the lid member of the second case section, then the sliding door can be properly assembled and supported, but the case dividing surface has to be formed in the vicinity of the door which restricts the layout of the air conditioning case and reduces design flexibility
Solution Approach 1:
The guide groove is divided into a groove lacking section and a groove formed section. The door support sections are strategically positioned relative to these sections, with specific relational expressions defining their distances. This segmentation allows the door to be properly supported while eliminating the need for a case dividing surface near the door, thereby resolving the contradiction between door support reliability and case layout flexibility.
2Adaptability or versatility
If door support sections are positioned within the groove lacking section, then the structure is simplified and design flexibility is improved, but abnormal rattling sound is generated during door operation
Solution Approach 1:
Different door support sections are positioned at specific locations relative to the groove lacking section based on their function. The first door support section (closest to the tip end) is positioned with distance A≤90−0.2L from the tip end, while other door support sections are positioned with distance D≤2(90−0.2L) between them. This localized positioning ensures that door support sections within the groove lacking section do not generate abnormal rattling sounds, while maintaining design flexibility.

AI summary
A sliding door has a door main body and door support sections supported by contact with an inner wall of a guide groove. The guide groove has a groove lacking section having a size that the door main body can be inserted therefrom. When a first one of the door support sections that is the closest to a tip end of the sliding door is located within the groove lacking section, another one of the door support sections that is located opposite from the tip end of the sliding door through the groove lacking section satisfies a relational expression of A≤90−0.2L, in which A represents a distance from the tip end to an end of the another one of the door support sections on a separated side away from the tip end, and L represents a door width of the door main body.
