Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide lamps experience loosening of swing rods due to external forces, leading to poor electrical contact and difficulty in assembly verification.
Innovation Solution
An adapter with a housing, swing rods, and an anti-retraction assembly that includes conductive and grounding spring pieces, limiting ribs, and sliding slots to secure electrical connections and ensure proper installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the swing rod is directly locked to fix it, then the loosening problem is solved, but it becomes inconvenient to disassemble and replace
Solution Approach 1:
The swing rod mechanism allows dynamic adjustment between locked and unlocked states. The swing rod can rotate to lock the guide rail in place, ensuring stable electrical contact, and can also be unlocked for easy disassembly and replacement, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The adapter is divided into separate components including the swing rod, housing, and guide rail sections. This segmentation allows the swing rod to be independently operated for locking/unlocking while maintaining overall structural integrity, enabling both stable contact and convenient disassembly.
2Ease of operation
If the swing rod is used for clamping, then the assembly is simple, but it is easy to loosen under external force causing poor electrical contact
Solution Approach 1:
The spring-loaded electrical contact components are pre-configured to apply continuous contact force against the guide rail. This preliminary anti-action counteracts external forces that might otherwise cause loosening, ensuring reliable electrical contact while maintaining simple swing rod clamping assembly.
Solution Approach 2:
The swing rod and guide rail interface incorporates curved or rounded surfaces that distribute contact forces more evenly. This curvature design prevents stress concentration that could lead to loosening, maintaining both assembly simplicity and electrical contact reliability.
3Device complexity
If the swing rod is invisible during assembly, then the structure is compact, but it is impossible to know whether it is assembled in place
Solution Approach 1:
The adapter incorporates visual indicators such as colored markings or transparent sections that change appearance or become visible when the swing rod is properly assembled. This allows assembly verification without adding significant structural complexity, resolving the contradiction between compactness and detectability.
Solution Approach 2:
A visual indicator component serves as an intermediary between the invisible swing rod assembly and the observer. This mediator provides visible feedback about assembly status without requiring the swing rod itself to be visible, maintaining structural compactness while enabling assembly verification.

AI summary
A connector (103), a guide rail assembly and a lamp (100). The connector (103) comprises: a housing (104), wherein the housing (104) is horizontally provided with a first through hole (1042) and a second through hole (1044), which penetrate the housing (104); a first swing rod (10), which has a first extension portion (111) extending from the inside of the housing (104) to the outside of the first through hole (1042); an electrical connection assembly (20), which has an electrically conductive elastic piece (21) protruding from the inside of the first extension portion (111); a second swing rod (30), which has a second extension portion (311) extending from the inside of the housing (104) to the outside of the second through hole (1044); and a retaining assembly, which is configured to limit the rotation of the first swing rod (10) and the second swing rod (30). By means of pushing the first swing rod (10), the lengths of the first extension portion (111) and the electrically conductive elastic piece (21) that extend to the outside of the first through hole (1042) can be changed, and by means of pushing the second swing rod (30), the length of the second extension portion (311) extending to the outside of the second through hole (1044) can be changed. By means of providing the retaining assembly, the electrically conductive elastic piece (21) can be prevented from loosening, such that poor contact between the electrical connection assembly (20) and a guide rail (102) is avoided, and whether the swing rod is installed in place can be indicated, so as to improve the hand feeling during installation.
