Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting shaft and plastic spacer are used to achieve rotational connection between the swivel arm and adapter, then the rotational function is achieved, but the structure becomes complicated and manufacturing precision requirements increase
Solution Approach 1:
The patent integrates the connecting shaft and rotational stop spacer functions into a single unified rotating shaft component. The rotating shaft includes a shaft body with integrated rotational stop features, eliminating the need for separate plastic spacer components. This merging of functions reduces structural complexity while maintaining reliable rotational connection between the swivel arm and adapter.
Solution Approach 2:
The rotating shaft is designed to perform multiple functions simultaneously: it provides the rotational connection axis, incorporates rotational stop features through its geometric design, and enables friction-based rotational control. This multi-functional design eliminates the need for specialized components like separate plastic spacers, simplifying the overall structure while maintaining all necessary functions.
2Adaptability or versatility
If a connecting shaft with rotational stop spacer is used, then rotational limitation is achieved, but manufacturing precision requirements and overall costs increase
Solution Approach 1:
The patent achieves rotational control by utilizing friction parameters between the rotating shaft and swivel arm bearing surfaces. By adjusting friction coefficients through material selection and surface treatment, the system controls rotational movement without requiring high-precision mechanical stop features. This parameter-based control reduces manufacturing precision requirements compared to rigid mechanical limiting structures.
Solution Approach 2:
The patent replaces the traditional mechanical rotational stop spacer system with a friction-based rotational control mechanism. Instead of using precision-machined mechanical limits, the system uses controlled friction between the rotating shaft surface and the swivel arm bearing surface to achieve rotational angle control, thereby reducing manufacturing precision requirements.
3Strength
If the swivel arm is made as a single piece, then structural integrity is maintained, but manufacturing complexity and costs increase
Solution Approach 1:
The patent divides the swivel arm into two separate half-casing components that are assembled together. This segmentation allows each half to be manufactured independently using simpler processes, reducing overall manufacturing complexity and costs. The two halves are then joined to form the complete swivel arm structure, maintaining structural integrity while enabling easier manufacturing.
4Reliability
If different materials are used for the half casings, then friction and abrasive characteristics are optimized, but manufacturing complexity increases
Solution Approach 1:
The patent applies different materials to different regions or components of the swivel arm assembly based on their specific functional requirements. The rotating shaft may use one material optimized for friction characteristics, while the half casings use materials optimized for structural strength and ease of manufacture. This localized material optimization improves performance without requiring complex multi-material construction throughout the entire assembly.

AI summary
The invention discloses a track lamp, comprising an adapter, a swivel arm and a lamp body, wherein the swivel arm comprises a first rotating shaft in tight fit connection with the adapter, and the first rotating shaft is divided into a first rotating half shaft and a second rotating half shaft along the direction vertical to a first rotating central line. The rotating shaft of the swivel arm is arranged in a split mode along the direction perpendicular to the first rotating center line, so that the rotating shaft is more convenient to manufacture. The swivel arm can be formed by connecting the first rotating half shaft and the second rotating half shaft, which is more convenient to mount on the adapter. By splitting the swivel arm into two half casings each preferably being made of a different material, the friction and abrasive characteristics of each of the rotation axes can be adjusted conveniently, and manufacturing costs can be reduced significantly.
