Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless alarm systems for building entrances, such as windows and doors, often require invasive installation methods that compromise insulation and aesthetics, and may not be easily retrofitted to existing structures without damaging them.
Innovation Solution
A slim, elongated sensor assembly with a microprocessor, wireless transmitter, and power source, designed to fit within the voids and cavities of windows and doors without modification, using ultrathin components and adhesive mounting to ensure non-invasive installation and concealment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless alarm systems are installed using invasive methods (bore holes, wires), then reliable sensor mounting is achieved, but insulation properties and aesthetics are compromised
Solution Approach 1:
The patent extracts the harmful elements (bore holes, wires, invasive mounting components) from the installation process. The sensor assembly is designed to be mounted surface-level using adhesive strips, eliminating the need for bore holes through the window/door and external wire routing, thus preserving insulation and aesthetics while maintaining reliable sensor functionality
Solution Approach 2:
The patent employs thin film adhesive mounting strips to secure the sensor assembly. This flexible, thin-film mounting method allows reliable attachment to the window or door frame surface without penetrating the structure, thereby maintaining insulation properties and visual appearance while providing secure sensor installation
2Manufacturing precision
If sensor assembly components are made larger for easier manufacturing, then manufacturing precision is improved, but the assembly cannot be concealed within narrow voids
Solution Approach 1:
The patent transitions the sensor assembly from a bulky three-dimensional form to a thin, planar configuration that can be mounted on the surface. By flattening the assembly and using surface mounting, the sensor fits within narrow voids and maintains aesthetic concealment while standard manufacturing processes can still produce the components with adequate precision
Solution Approach 2:
The sensor assembly utilizes thin-film construction and flexible mounting strips to achieve a profile thin enough to be concealed within narrow voids between window/door components, while standard manufacturing techniques maintain sufficient fabrication accuracy for the smaller dimensions
3Ease of operation
If adhesive mounting is used for non-invasive installation, then ease of installation is improved, but mounting strength may be reduced
Solution Approach 1:
The patent combines multiple adhesive mounting strips with the sensor assembly housing to create a unified mounting structure. This integration ensures that the adhesive mounting system provides sufficient attachment strength while maintaining the simplicity of tool-free installation, resolving the contradiction between ease of installation and mounting strength
