Method for precisely positioning an inner casing in an external casing of an air conditioned cabinet and air conditioned cabinet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The precise positioning of an inner boiler within an outer boiler in climate chambers is challenging due to manufacturing tolerances, leading to instability and reproducibility issues, even with two employees involved in the production process.
Innovation Solution
A method involving a component of the inner boiler with a lower height than the outer boiler, equipped with a movable foot that adjusts in height to ensure precise fitting by supporting the component on the ceiling and floor of the outer boiler, allowing for compensation of tolerances and easier assembly by applying force in the access direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a component of the inner boiler is adapted precisely to the dimension of the outer boiler, then the fit between inner and outer boiler is improved, but the ease of assembly deteriorates due to difficulty in introducing the component into the outer boiler
Solution Approach 1:
The foot is designed as a movable adjustment element that can be positioned at different heights along the guide rail. This dynamic adjustment capability allows the inner boiler component to be easily inserted in a reduced state and then precisely positioned against the ceiling of the outer boiler by moving the foot to the appropriate height, resolving the contradiction between easy assembly and precise fit.
Solution Approach 2:
The height of the foot is variable and can be adjusted to compensate for manufacturing tolerances. By changing the height parameter of the foot, the system achieves precise positioning of the inner boiler component against the ceiling while maintaining ease of assembly through the adjustment mechanism.
2Manufacturing precision
If manufacturing tolerances are strictly controlled to achieve precise positioning, then the positioning accuracy is improved, but the production complexity and cost increase
Solution Approach 1:
Instead of controlling manufacturing tolerances strictly, the invention uses an adjustable foot with variable height to compensate for tolerances. This shifts the precision requirement from manufacturing to assembly, where the foot height can be adjusted to achieve accurate positioning without requiring complex production control.
Solution Approach 2:
The adjustable foot mechanism allows operators to self-adjust the positioning of the inner boiler component during assembly. This self-adjustment capability eliminates the need for complex pre-control of manufacturing tolerances, simplifying production while maintaining positioning accuracy.
3Reliability
If two employees are involved in the production step to improve positioning reliability, then the positioning stability is improved, but the productivity deteriorates due to increased time consumption
Solution Approach 1:
The adjustable foot mechanism enables one operator to independently adjust and secure the positioning of the inner boiler component. The self-adjusting nature of the mechanism eliminates the need for a second employee, maintaining positioning reliability while improving productivity by reducing labor requirements.
4Ease of manufacture
If a component of the inner boiler with lower height is used, then the ease of assembly is improved, but the initial fit precision deteriorates until the foot is adjusted
Solution Approach 1:
The foot is designed as a dynamic adjustment element that transforms the initially imprecise fit (with lower height component) into a precise final fit. The movability of the foot allows it to be positioned at the correct height to contact the ceiling of the outer boiler, converting the reduced-height component into a precisely fitted assembly.
