Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface-mounted lights and cameras for process chambers in machines require complex assembly and disassembly, are prone to dirt accumulation, and can be loosened by vibrations, posing challenges for maintenance and hygiene, especially in the food industry.
Innovation Solution
A surface-mounted light and camera system with a connecting pin that allows tool-free mounting and secure fastening using a beveled recess and U-shaped fastening means, forming a releasable connection that withstands vibrations and shocks, and is designed to prevent dirt accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connections are used to fasten the surface-mounted light to the wall, then the connection is secure and can withstand vibrations, but the assembly and disassembly require tools and are complex, and dirt can accumulate in the screw connections
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a spring-loaded clamp mechanism. The spring element provides continuous clamping force to secure the surface-mounted light to the wall, eliminating the need for screws while maintaining fastening reliability. This substitution enables tool-free assembly and disassembly, directly resolving the contradiction between secure fastening and ease of operation.
Solution Approach 2:
The invention extracts the fastening function from the surface-mounted light housing and implements it separately through wall-mounted spring clamps. This separation allows the light unit to be freely removable without carrying fastening elements, eliminating dirt accumulation points in screw connections while maintaining secure attachment during operation.
2Reliability
If screw connections are used to fasten the surface-mounted light to the wall, then the connection is secure, but the fastening means lead to accumulation of dirt and offer gaps for germs
Solution Approach 1:
The patent replaces screw connections with a spring-loaded clamp system that creates a smooth, continuous fastening interface. The spring clamp envelops the mounting surface without creating gaps or pockets, eliminating dirt accumulation zones while maintaining secure fastening. This is particularly important for hygiene-sensitive environments like food processing facilities.
Solution Approach 2:
The spring element acts as a flexible fastening component that conforms to the mounting surface, creating a seamless connection without sharp edges or gaps where dirt could accumulate. The flexible nature of the spring clamp allows it to maintain contact pressure while presenting a clean, easy-to-clean surface.
3Ease of operation
If a simple fastening system is used for the surface-mounted light, then assembly is quick and tool-free, but the fastening may loosen under vibrations and shocks
Solution Approach 1:
The patent employs a dynamic spring-based fastening system instead of static screw connections. The spring element can dynamically adjust to vibrations and shocks, maintaining constant clamping force on the surface-mounted light. This dynamic response ensures the fastening remains secure under vibrational conditions while allowing for simple, tool-free assembly.
Solution Approach 2:
The spring-loaded clamp provides beforehand cushioning against vibrational forces by maintaining pre-loaded clamping pressure. This pre-compression compensates for the effects of vibrations and shocks before they can cause loosening, ensuring reliable fastening without complex anti-vibration mechanisms.

Function Achieved in This Case
Enables quick, tool-free installation and secure retention of the light or camera, even under vibrational conditions, while maintaining cleanliness and allowing for easy maintenance, suitable for use in the food industry.
Implementation Method 1
The trap is configured to make an elastic evasive movement when the connecting pin is inserted and to snap into a connection between the connecting pin and the surface-mounted lights in the manner of a catch
