Method for the precisely fitting positioning of an inner boiler in the outer boiler of an air-conditioning cabinet and air-conditioning cabinet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The precise fitting and stable positioning of an inner chamber within an air-conditioning cabinet's outer chamber is challenging due to manufacturing tolerances, making it difficult to achieve a secure and reproducible fit, especially at the cover-side contact line.
Innovation Solution
The method involves using an inner chamber component with a movable foot that can adjust its height to precisely fit within the outer chamber by shifting the foot's position, allowing it to be supported on the cover and bottom, and fixing it in place, thereby compensating for tolerances and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the inner chamber component is dimensioned to precisely fit the outer chamber, then the fitting precision is improved, but the ease of manufacture deteriorates due to difficulty in introduction and assembly
Solution Approach 1:
The foot is designed to be movable relative to the inner chamber component, allowing dynamic adjustment of the component's position and height. This enables the component to be easily introduced into the outer chamber and then precisely positioned by moving the foot, resolving the contradiction between easy assembly and precise fitting.
Solution Approach 2:
The height of the inner chamber component is made variable through the movable foot mechanism. By changing the position parameter of the foot, the component can be adjusted to achieve precise fitting with the cover, while the component itself can be manufactured with a standard, easier-to-manufacture dimension.
2Manufacturing precision
If the inner chamber component is made with exact dimensions to match the outer chamber, then the fitting precision is improved, but the adaptability deteriorates due to inability to compensate for manufacturing tolerances
Solution Approach 1:
The movable foot provides dynamic adjustment capability that allows the inner chamber component to adapt to variations in outer chamber dimensions. This resolves the contradiction by enabling both precise fitting and tolerance compensation through the same mechanism.
Solution Approach 2:
By making the height parameter of the inner chamber component adjustable via the movable foot, the system can compensate for manufacturing tolerances in the outer chamber while still achieving precise fitting. The component is not constrained to fixed dimensions, providing adaptability.
3Stability of the object's composition
If two co-workers are involved in the positioning process, then the stability is improved, but the productivity deteriorates due to time-consuming manual adjustment
Solution Approach 1:
The movable foot mechanism enables the inner chamber component to be self-positioned within the outer chamber. The component can be adjusted and secured without requiring multiple workers, thus maintaining positioning stability while improving assembly productivity by reducing labor requirements.
4Ease of manufacture
If the component is dimensioned too small to facilitate assembly, then the ease of manufacture is improved, but the manufacturing precision deteriorates due to gap and misalignment
Solution Approach 1:
The movable foot transforms the static, poorly-fitting small component into a dynamically adjustable element. The component can be easily assembled in a smaller size and then precisely positioned by moving the foot, resolving the contradiction between easy assembly and precise fitting.
Solution Approach 2:
The component is preliminarily assembled in a smaller, easier-to-manufacture size, and then the foot is adjusted to achieve the final precise positioning. This preliminary action approach resolves the contradiction by separating the assembly ease requirement from the precision requirement.

AI summary
An air-conditioning cabinet can have an outer chamber, an inner chamber with an inner chamber height, a cover, a bottom where the cover and bottom are separated by a distance that defines the inner chamber height, an inner chamber having a foot movably coupled to the inner chamber, where the inner chamber is arranged in the outer chamber, where the inner chamber height is less than the inner chamber height and where the foot is movably coupled to the inner chamber in such a manner that the inner chamber height is variable. Also, moving a position of the foot on the inner chamber can arrange the inner chamber such that the inner chamber is supported on the cover of the outer chamber and the foot is supported on the bottom of the outer chamber, and the foot can be fixed in the position.
