Lighting System Vibration Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps are prone to damage during vibrations such as earthquakes or storms, leading to loose electric wires and potential electric shocks or fires due to short circuits.
Innovation Solution
A compact safer tightly secured lighting system is designed with a heat sink and lamp housing structure that includes a recessed slot for the illumination element, a circular recess for the temperature controller, and a hose-end tightening mechanism to secure electric wires, along with a locking mechanism for the terminal box and torsional spring devices to prevent components from dislodging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lamp components are mounted using standard connections, then the lamp can be easily assembled and disassembled, but the components may come off or separate due to vibration during earthquakes or storms
Solution Approach 1:
The connection structure is divided into modular components including locking mechanisms with locking balls, groove structures, and separate mounting brackets. Each component performs a specific function in the securing process, allowing the system to achieve high reliability through coordinated modular elements rather than a single complex connection point.
Solution Approach 2:
The locking mechanisms are pre-configured with locking balls positioned in grooves, and mounting brackets are pre-attached to components before final assembly. This preliminary positioning ensures that during vibration events, the components are already secured in their correct positions and cannot easily disengage.
2Reliability
If electric wires are routed through standard pathways, then the wiring is simple to install, but the wires may loosen or fall off during vibrations causing short circuits
Solution Approach 1:
Electric wires are nested within protective conduits or channels that are integrated into the lamp structure. The wires are routed through hollow passages in mounting brackets and housing components, providing mechanical protection and preventing disconnection during vibration while maintaining a compact overall structure.
Solution Approach 2:
The wire protection system uses flexible conduits or thin-walled protective channels that can accommodate wire movement while maintaining secure routing. These flexible protective elements bend and flex with vibration but continue to constrain the wires within safe pathways, preventing exposure and short circuit risks.
3Reliability
If the lamp housing uses simple fastening methods, then manufacturing and assembly are easier, but the housing may not remain tightly secured during strong vibrations
Solution Approach 1:
The locking mechanisms are designed to automatically engage and lock components in place during the assembly process itself. For example, locking balls are positioned to automatically engage with grooves when components are brought together, providing self-securing functionality that maintains reliability without requiring additional manual fastening steps or complex assembly procedures.

AI summary
A compact safer tightly secured lighting system comprises an illumination element module, a terminal box, an illumination element module driver, and a junction box, wherein the illumination element module is composed of a heat sink and a lamp housing. An outer wall of a lower end of the heat sink has a circular recess provided for embedding a temperature controller. The lamp housing is composed of an external case, a reflective cup, a protection mask and a plurality of circlips having elasticity. A spacing is between the outer wall of the protection mask and the internal wall of the external case. The circlip is disposed to an outer wall of the protection mask, where one end is joined to a top end of the protection mask while another end has a tooth buckle corresponding to the internal wall of the external case. The tooth buckle stretches into the spacing to allow the circlip to locate between the external case and the protection mask so as to closely combine the protection mask and the external case. The terminal box is locked and connected by a locking mechanism.
