Ceiling Fan Lighting Unit Anti-Remodeling Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling fans with easily disassemblable lighting units are prone to illegal remodeling due to their reassembly capabilities, posing a need for a structure that can be easily disassembled for repair or manufacturing while preventing unauthorized modifications.
Innovation Solution
The ceiling fan design incorporates a lighting unit with an upper and lower lighting cover, a light-emitting unit, and a cover that uses protrusions, installing portions, and breaking portions to secure the components together, allowing for controlled disassembly and reassembly without facilitating illegal remodeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the lighting unit is designed to be easily disassembled for repair or manufacturing, then the ease of repair and manufacturing is improved, but the risk of illegal remodeling increases
Solution Approach 1:
The patent applies preliminary action by providing breaking portions that are pre-designed to break when the cover is detached. This preliminary structural arrangement ensures that once the cover is removed for repair or manufacturing, the breaking portions automatically break, preventing illegal remodeling. The breaking portions are positioned and dimensioned in advance to achieve this protective function upon disassembly.
Solution Approach 2:
The patent applies local quality by making only specific portions of the cover breakable, rather than the entire structure. The breaking portions are localized areas with reduced strength or pre-formed fracture lines, allowing the cover to maintain its protective function in most areas while having controlled weak points that break upon detachment. This localized approach enables both easy disassembly and prevention of illegal remodeling.
2Ease of manufacture
If the lighting unit uses a structure that can be reassembled after disassembly, then the ease of manufacture is improved, but the ability to prevent illegal remodeling deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-arranging the breaking portions in specific locations and configurations before assembly. These breaking portions are designed in advance to break when the cover is detached, creating a one-time use mechanism. The protrusions and recesses are also pre-configured to guide proper reassembly, ensuring that even after breaking, the unit can be legally reassembled but not illegally remodeled.
Solution Approach 2:
The patent converts the potential harm of easy disassembly (which enables illegal remodeling) into a benefit by designing breaking portions that break upon detachment. The act of disassembly, which could enable illegal remodeling, instead triggers the breaking of these portions, thereby preventing future illegal remodeling while still allowing legitimate repair or manufacturing activities.

AI summary
A first protrusion protruding from an upper lighting cover is fitted into a first installing portion provided in a cover and a second protrusion protruding from the upper lighting cover is inserted into a first hole provided in the cover. In a case where disassembly is performed from this state, disassembly can be accomplished by breaking a first breaking portion provided around the first installing portion. In a case where reassembly is performed from this state, the second protrusion protruding from the upper lighting cover is fitted into a second installing portion provided in the cover.
