Innovation Solution
A method involving thermoforming of shells and bodies from moldable materials like plastic or fiberglass, with secure assembly to create a weather-resistant enclosure that meets DoITT specifications, using vacuum forming and securing mechanisms like adhesive and fastening systems to ensure RF signal transmission and weather-tight sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If thermoforming is used to manufacture enclosures, then manufacturing cost is reduced and production efficiency is improved, but producing overlapping joints or transitions becomes difficult without intricate detailing
Solution Approach 1:
The enclosure is divided into multiple separate thermoformed components (front wall, rear wall, side walls, base) that are assembled together using overlapping joints. This segmentation allows each component to be thermoformed independently with standard detailing, while the overall enclosure achieves the required precision through the assembly of these segmented parts with overlapping joints.
2Manufacturing precision
If injection molding is used to manufacture enclosures, then manufacturing precision is improved, but manufacturing cost increases significantly
Solution Approach 1:
The enclosure is segmented into multiple thermoformed components that are assembled together. This approach achieves the required manufacturing precision through the assembly process and overlapping joints rather than requiring a single complex injection molded part, thereby significantly reducing manufacturing cost while maintaining precision.
Solution Approach 2:
The patent uses thermoformed plastic shells and panels to create the enclosure components. Thermoforming allows for cost-effective production of precise plastic parts with complex geometries, including overlapping joints and transitions, by using heated and formed thin plastic sheets, achieving both precision and cost-effectiveness.
3Strength
If the enclosure is made as a single integrated part, then structural strength is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The enclosure is divided into multiple components (front wall, rear wall, side walls, base) that are assembled together. The overlapping joints and fastening systems create strong structural connections between these segmented parts, achieving sufficient enclosure strength without requiring a single complex integrated part, thereby reducing manufacturing complexity.
Solution Approach 2:
Multiple separately manufactured components are merged together through overlapping joints and fastening systems to form the complete enclosure. This merging process creates a structurally strong assembly that meets strength requirements while keeping individual components simple and easy to manufacture.
