Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial lighting devices face challenges in withstanding extreme vibrations and requiring adaptable lighting conditions, particularly in environments with high accelerations and varying illumination needs.
Innovation Solution
The design incorporates a waterproof housing with a glass window, a seal, and a filter system featuring an elastic compression member that absorbs vibrations and allows for easy filter replacement, enabling the device to maintain attachment and adjust lighting configurations under severe conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the filter is rigidly fixed to the housing, then the structural strength is improved, but the device cannot withstand extreme vibrations and the filter cannot be easily replaced
Solution Approach 1:
The patent employs a flexible frame structure with elastic compression members that can deform under vibration stress, allowing the filter assembly to flexibly absorb extreme vibrations while maintaining the integrity of the rigid filter element itself. The frame acts as a flexible mounting structure rather than a rigid one.
Solution Approach 2:
The elastic compression members provide a dynamic mounting solution where the filter can be easily installed and removed, and the mounting structure itself dynamically responds to vibrations through elastic deformation. This dynamic characteristic allows both easy replacement and vibration resistance.
2Strength
If the filter is tightly secured to prevent tearing, then the resistance to vibration-induced tearing is improved, but the filter replacement becomes difficult and manufacturing tolerances are not compensated
Solution Approach 1:
The patent divides the mounting system into separate functional elements: a removable frame assembly with elastic compression members that can be independently installed and removed, while the filter element itself remains intact. This segmentation allows easy replacement of the entire filter assembly without damaging the filter.
Solution Approach 2:
The elastic compression members are pre-installed in the frame structure to provide cushioning against vibration-induced tearing forces before they can damage the filter. This beforehand cushioning protects the filter while allowing easy assembly and disassembly.
3Reliability
If the housing structure is made rigid to maintain sealing, then the waterproof sealing is improved, but the device cannot adapt to manufacturing tolerances and vibration-induced misalignment
Solution Approach 1:
The elastic compression members and flexible frame structure can deform to accommodate manufacturing tolerances in the housing and filter assembly, while the seal maintains its sealing function. The flexibility allows the system to adapt to dimensional variations without compromising the waterproof seal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides high resistance to tearing during vibrations, compensates for manufacturing tolerances, and allows for easy modification of lighting conditions by enabling quick filter replacement, ensuring reliable operation in environments with high accelerations.
Implementation Method 1
The elastic compression member is arranged so as to absorb at least part of the vibrations transmitted to the filter by the support
Implementation Method 2
an elastic compression member arranged between the support and the frame, in which the elastic compression member is arranged so as to elastically push an edge of the frame towards the frame window
Implementation Method 3
the elastic compression member is arranged so as to elastically push an edge of the frame towards the frame window and/or so as to elastically push the frame against the window
