Solution Overview
Problem
Currently available light tubes lack appropriate mistake-proof structures, leading to incorrect installations on incompatible installation bases, which can result in damage or accidents such as fires.
Innovation Solution
A lighting device with a mistake-proof structure is designed, featuring holders with conductive plates and rotational fixing elements, and light tubes with end caps having extending spaces that engage with the extending portions of the rotational fixing elements, ensuring correct installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If light tubes are made simple and replaceable, then ease of operation is improved, but mistake-proof structure is lacking leading to incorrect installations
Solution Approach 1:
The patent applies asymmetry by designing the extending portion of the rotational fixing element with a specific shape (e.g., L-shaped, T-shaped, or asymmetric protrusion) that only fits into the corresponding extending space of the end cap when rotated to the correct angle. This asymmetric geometry prevents incorrect installations by making it physically impossible to install the light tube in wrong orientations, thus maintaining ease of operation while ensuring installation correctness.
Solution Approach 2:
The patent introduces an intermediary mechanism - the rotational fixing element with extending portion and extending space - that mediates between the simple replaceable light tube and the holder. This intermediary structure provides the mistake-proof function by requiring a specific rotational alignment for proper engagement, thereby ensuring installation correctness without complicating the overall replacement process.
2Reliability
If mistake-proof structure is added to light tubes, then installation correctness is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the fixing mechanism into separate functional components: the end cap with extending space, the rotational fixing element with extending portion, and the holder body. This segmentation allows each component to perform its specific function independently, providing mistake-proof installation capability while keeping the overall structure relatively simple and manageable.
Solution Approach 2:
The patent applies local quality by adding the mistake-proof features (extending portion and extending space) only at specific locations - the end caps and rotational fixing elements - rather than redesigning the entire light tube or holder system. This localized approach provides installation correctness while minimizing the increase in overall device complexity.
3Stability of the object's composition
If rotational fixing element is used, then structural stability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies merging by combining the rotational fixing element with the holder body or making it an integrated component that rotates within the holder. This merging reduces the number of separate parts that need to be manufactured and assembled, thereby improving structural stability through the rotational fixing mechanism while minimizing the increase in manufacturing complexity.

AI summary
A method for installing a lighting device having a mistake-proof structure includes the following steps: aligning the two end caps at the two ends of the tube body of a light tube with two holders; installing the two end caps on the two holders to make the extending space of each of the end caps be engaged with the extending portion of the rotational fixing element of the holder corresponding thereto; and making the two conductive pins of each of the end caps contact the two conductive plates in the holder body of the holder corresponding thereto.
