Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting light sources on roofing structures, particularly LED strips, face issues with adhesive bonding that can weaken over time and lack a secure, tool-free, and aesthetically pleasing fastening solution.
Innovation Solution
A method involving a fastening element with a handle that secures a strip-like light source in a recess of a structural element, allowing for tool-free installation and easy detachment by manually manipulating a predetermined breaking point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive bonding is used to mount LED strips on structural elements, then the installation process is simple and initial attachment is easy, but the bonding strength weakens over time and reliability deteriorates
Solution Approach 1:
The fastening system is segmented into a fastening element with handle, a structural element with recess, and a mounting bracket. This segmentation allows the adhesive to be applied only to specific mounting surfaces rather than the entire LED strip, concentrating the bonding effort where needed while maintaining overall reliability through the mechanical fastening structure.
Solution Approach 2:
The fastening element with handle acts as an intermediary between the structural element and the LED strip. It provides a mechanical connection that supplements the adhesive bonding, ensuring that the LED strip remains securely mounted over time without relying solely on the adhesive's bonding strength.
2Reliability
If mechanical fastening elements are used to secure LED strips, then the mounting reliability is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The fastening element with handle is designed to be self-installing. The handle provides leverage for the installer to manually snap the fastening element into the recess of the structural element without requiring additional tools or complex assembly procedures. This self-service design maintains mounting reliability while minimizing device complexity.
Solution Approach 2:
The fastening element with handle is designed as a simple, inexpensive plastic component that can be easily replaced if needed. Its simple geometry and single-function design reduce manufacturing complexity while providing reliable mounting. The handle breaks off after use, indicating the fastening element has served its purpose.
3Shape
If adhesive mounting is used for LED strips, then the appearance is clean and aesthetic, but the mounting can be damaged during insertion and handling
Solution Approach 1:
The LED strip is pre-mounted to a mounting bracket using adhesive in a controlled manufacturing environment where the adhesive can properly cure. This preliminary action protects the adhesive bond from damage during subsequent handling and installation, as the LED strip is already secured to the rigid bracket structure.
Solution Approach 2:
The mounting bracket serves as an intermediary between the adhesive bond and the structural element. The adhesive is applied between the LED strip and the bracket rather than directly to the structural element, protecting the adhesive from mechanical stress and environmental factors while maintaining a clean aesthetic appearance.
4Reliability
If permanent adhesive bonding is used, then the LED strips are securely fixed, but the ability to remove or replace the LED strips is lost
Solution Approach 1:
The mounting system is segmented into removable components: the fastening element with handle can be pried off the structural element, and the LED strip can be removed from the mounting bracket. This segmentation maintains secure fixing during use while enabling easy removal and replacement when needed, addressing both reliability and ease of repair requirements.
Solution Approach 2:
The mounting system transitions from a static permanent bond to a dynamic reversible connection. The fastening element with handle provides a mechanical connection that is secure during normal use but can be easily disengaged by prying the handle off the structural element recess, allowing the LED strip to be removed or replaced without damaging the structural element.
