Innovation Solution
A multiple seal electronic display module with displacement springs and latch assemblies is introduced, featuring a geometrically configured front edge seal, flexible seals for signal and power jacks, and an overmolded programming jack seal, ensuring secure attachment and sealing against environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive sealing methods are used, then sealing coverage can be extensive, but the application process becomes labor intensive and inconsistent
Solution Approach 1:
The patent replaces adhesive chemical bonding with a mechanical sealing system using compression seals and gaskets that are inserted into grooves and compressed between mating surfaces. This mechanical approach eliminates the labor-intensive and inconsistent adhesive application process while providing reliable, repeatable sealing through precise mechanical compression forces.
Solution Approach 2:
The patent changes the sealing mechanism from chemical adhesion to mechanical compression by controlling compression force parameters. Compression seals are designed with specific compression rates and forces that ensure consistent sealing without requiring manual adhesive application, thereby improving both reliability and ease of manufacture.
2Stability of the object's composition
If display modules are securely mounted to prevent misalignment, then alignment stability improves, but the mounting system becomes more complex
Solution Approach 1:
The patent incorporates alignment features and pre-positioning mechanisms into the mounting system that automatically guide and position display modules correctly during installation. This preliminary alignment action prevents misalignment before it occurs, maintaining alignment stability without requiring complex adjustment mechanisms or procedures.
Solution Approach 2:
The mounting system includes self-aligning features such as tapered mounting surfaces and的定位 features that automatically position display modules in the correct alignment when installed. This self-service capability maintains alignment stability while minimizing the complexity of the mounting system by eliminating the need for complex external alignment devices.
3Object-affected harmful factors
If multiple sealing points are implemented, then protection against environmental ingress improves, but the manufacturing process becomes more complex
Solution Approach 1:
The patent divides the sealing system into multiple discrete compression seals and gaskets positioned at different locations (front seal, rear seal, jack seals). Each seal is a separate, standardized component that can be independently manufactured and installed, providing comprehensive environmental protection while maintaining manufacturing simplicity through modular assembly.
Solution Approach 2:
The patent uses standardized compression seal components with consistent compression parameters across multiple sealing points. This standardization allows multiple seals to be manufactured and installed using the same processes and techniques, providing enhanced environmental protection without increasing manufacturing complexity.
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 secure and consistent mounting, prevents misalignment and water ingress, and enhances the reliability and durability of electronic sign displays by ensuring all components are properly sealed and securely attached.
Implementation Method 1
Displacement springs are mounted to the latch assemblies, where the displacement springs interface with and create an interference between the mounting panel of the electronic sign and the electronic display module

AI summary
The present invention provides a multiple seal electronic display module having displacement springs for distributed use as major components of an electronic sign. Displacement springs are provided to displace the electronic display module from the front of an electronic sign mounting panel until latching mechanisms are properly actuated in order to secure the electronic display module to the electronic sign mounting panel and thus provide a visual clue indicating proper or improper securing. A configured front edge seal provides for multiple surface sealing of multiple components consisting of, but not limited to, a louver panel, an LED circuit board, and a housing. A rear seal is also provided to seal the rear of the electronic display module to the electronic sign mounting panel. Input and output signal jack base seals and a power jack base seal provide effective seals between the housing and the signal and power jacks.
