Handrail Lighting Fixture with Modular LED Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handrail lighting systems require cumbersome and time-consuming installation and replacement of flexible LED arrays, which can cause damage to the miniature electronic circuits and are costly to remove and replace, necessitating the involvement of skilled professionals.
Innovation Solution
A channel system for handrails that allows for the simple and variable installation and replacement of LED arrays without the need for lenses or secondary covers, enabling the LED arrays to be inserted or removed from one end, reducing labor and allowing for mechanical installation of handrail components before electrical components, thus avoiding potential damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible LED arrays are pressed into channels between posts or wall brackets, then the LED arrays can be retained in place, but the installation process becomes cumbersome and time-consuming, and the miniature electronic circuits and LEDs may be damaged
Solution Approach 1:
The lighting system is divided into modular segments where each channel assembly (handrail section with integrated channel) can be independently handled and installed. The LED array is separated from the handrail structure, allowing the handrail to be installed first, followed by insertion of the LED array into the pre-formed channel.
Solution Approach 2:
The channel is pre-formed as an integral part of the handrail assembly during handrail manufacturing, before the LED array is installed. This preliminary preparation of the mounting structure eliminates the need for complex installation procedures and protects the LED array from damage during installation.
2Reliability
If lenses are used to retain flexible LED arrays in channels, then accidental removal or vandalism is inhibited, but the installation becomes more complex and time-consuming
Solution Approach 1:
The channel and the handrail are merged into a single integrated structure, with the channel formed as an integral part of the handrail cross-section. This eliminates the need for separate retention mechanisms like lenses or secondary covers, simplifying both the overall device structure and the installation process while maintaining secure retention of the LED array.
3Reliability
If LED arrays are installed between posts or wall brackets, then lighting can be provided along handrails, but removal and replacement requires dismantling the entire handrail assembly, increasing labor costs
Solution Approach 1:
The lighting system is segmented into independent modular units where the LED array is separated from the handrail structure. Each channel assembly can be independently accessed, allowing the LED array to be removed and replaced without affecting the handrail or other components, significantly reducing maintenance complexity and cost.
Solution Approach 2:
The LED array is extracted from the handrail structure and placed into a separate channel that is part of the handrail but does not require dismantling the handrail for access. This extraction allows the LED array to be independently removed and replaced by simply accessing the channel opening.
4Strength
If welding operations are performed during handrail installation, then handrails can be securely assembled, but LED components may be damaged by the heat
Solution Approach 1:
The handrail structure is completely assembled and welded before the LED array is installed. The channel is prepared in advance as part of the handrail structure, allowing the welding operations to be completed without risk of damaging LED components. The LED array is then inserted into the pre-formed channel after all high-temperature operations are finished.
