Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hazard detection centers, such as intrusion alarms and fire detection systems, face challenges in rapid identification of alarms, robust design, protection against damage and electrostatic discharges, and complex servicing due to sensitive printed circuit boards and labeling issues.
Innovation Solution
A support component with latching means for secure attachment to the housing and printed circuit board, an operating region for force transmission, and guide means for labeling, allowing for tool-free servicing and reduced stress on printed circuit boards, enhancing robustness and modular structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the indicator and operator control component is arranged in the interior of the housing, then the housing structure is compact, but rapid identification of alarm location is prevented or made difficult since rescue personnel first have to open the housing
Solution Approach 1:
The housing is divided into a fixed part and a removable cover part, allowing the indicator and operator control component to be accessible from the outside while maintaining a compact overall structure. The removable cover enables quick access without dismantling the entire housing.
Solution Approach 2:
A removable cover acts as an intermediary element between the exterior and the indicator and operator control component located in the interior. This cover can be quickly removed to access the component, solving the contradiction between compact housing and rapid accessibility.
2Speed
If the indicator and operator control component is arranged on the side of the housing accessible from the outside, then rapid identification of alarm location is enabled, but installation, start-up and servicing become more complex
Solution Approach 1:
The housing is segmented into a fixed base and a removable cover, concentrating the indicator and operator control component on the removable cover. This allows external accessibility for rapid alarm identification while simplifying installation and servicing by enabling easy removal and replacement of the entire cover assembly.
3Strength
If printed circuit boards are fastened to the indicator and operator control component using screws, then secure mechanical attachment is achieved, but the processes of screwing on and moving the printed circuit board frequently lead to damage
Solution Approach 1:
The mechanical screw-fastening system is replaced with a snap-fit connection system. The printed circuit board is retained by elastic deformation of plastic elements, eliminating the need for screws and avoiding damage to the printed circuit board during installation and movement while maintaining secure attachment.
Solution Approach 2:
The fastening mechanism changes from rigid mechanical screws to elastic plastic deformation. The elastic elements deform during insertion to secure the printed circuit board, providing secure attachment without the sharp edges and high stresses of screw fasteners that cause damage.
4Adaptability or versatility
If labels are printed on paper and inserted into a holder, then labeling flexibility and updates are easy, but the labels are sensitive to vibrations and other stresses
Solution Approach 1:
The label system uses a composite structure combining a vibration-resistant background material with printable surface layers. This allows the label to maintain flexibility for updates while the background material provides resistance to vibrations and stresses, protecting the printed information.
