Electric Control Box and Air Conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection methods for electric-control-box covers in ceiling-mounted air conditioners either require manual holding to prevent falling during installation, risking injury, or increase manufacturing complexity and cost with additional components like pins.
Innovation Solution
A socket mechanism in the electric-control-box body allows the cover to be inserted and positioned, maintaining a cantilevered state without additional fasteners, simplifying installation and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If four screws are used for fastening the electric-control-box cover, then the connection strength is improved, but the installation complexity and safety risk increase due to manual handling requirements
Solution Approach 1:
The patent extracts the manual handling requirement from the installation process by designing a cover that can be suspended during installation. The cover is equipped with a suspension structure that allows it to be hung on the installation support, eliminating the need for installers to manually hold the cover while securing it with screws.
Solution Approach 2:
The patent introduces an installation support as an intermediary element between the cover and the installer. This support structure provides a hanging point that mediates the installation process, allowing the cover to be securely positioned without direct manual handling during the screw-fastening operation.
2Reliability
If two screws and a pin structure are used for fastening, then the cover falling problem is solved, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent removes the additional pin component from the fastening system. Instead of using two screws plus a pin, the design employs only two screws配合with a suspension structure that integrates into the cover itself, eliminating the need for separate pin manufacturing and assembly.
Solution Approach 2:
The patent merges the suspension function and fastening function into a unified structure. The suspension structure is integrated with the cover design, combining what were previously separate functions (suspension and fastening) into a single integrated system that reduces component count and manufacturing complexity.
