Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection structure between the filter screen and the housing of an air conditioner's indoor unit is prone to damage during disassembly, requiring professional tools and skills, making frequent cleaning and maintenance challenging.
Innovation Solution
A rotating connection structure featuring a fixed member with a rotating shaft groove, mounting groove, and limiting groove, allowing the filter assembly to rotate within a preset angle range, facilitating easy disassembly and assembly without damaging the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the filter screen is connected to the housing by forcibly clamping an elastic end into a round hole, then the connection is secure, but the connection structure is damaged during disassembly requiring professional tools and skills
Solution Approach 1:
The connection structure transitions from a static forced-clamp design to a dynamic rotating connection. The elastic end is configured to rotate relative to the housing within a preset angle range, allowing the filter screen to be easily detached by rotating it out of engagement, while maintaining secure connection during normal operation. This dynamic mechanism eliminates the need for professional tools and skills for disassembly.
Solution Approach 2:
The connection structure is divided into distinct functional components: a fixed member on the housing, a rotating member on the filter screen, and an elastic end that provides both connection and rotation capability. This segmentation allows each component to perform its specific function optimally - the elastic end provides secure connection while the rotating mechanism enables easy disassembly.
2Reliability
If the filter screen is frequently detached and cleaned, then air quality is maintained, but the connection structure is damaged requiring professional disassembly tools
Solution Approach 1:
The rotating connection structure enables the filter screen to be easily detached and reattached by users without requiring professional tools or skills. The simple rotation mechanism allows frequent maintenance operations to be performed as needed, ensuring air quality is maintained while eliminating the complexity of professional disassembly procedures.
3Stability of the object's composition
If the elastic end is forcibly clamped into the round hole, then the filter screen is securely fixed, but repeated disassembly and assembly causes damage to the connection structure
Solution Approach 1:
The connection structure incorporates a rotating mechanism that allows the filter screen to be easily detached and reattached without damaging the connection components. The elastic end rotates within a preset angle range during detachment and reattachment, preventing the cumulative damage that would occur with repeated forced clamping and release operations.
Solution Approach 2:
The elastic end is designed with inherent elasticity and rotation capability to cushion the stresses of repeated disassembly and assembly operations. This prior cushioning design prevents damage accumulation in the connection structure, maintaining both fixation stability and connection durability over time.
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
Enables convenient and repeated disassembly and assembly of the filter assembly without damaging the connection structure, improving maintenance accessibility and reducing the risk of damage.
Implementation Method 1
the elastic end is elastically deformed when rotating from the mounting groove to the rotating shaft groove, and recovers from the elastic deformation and is limited in the limiting groove
