Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adhesive films are used without conductive components, then the adhesive strip maintains simple structure and manufacturing, but it cannot supply power or transport data to components
Solution Approach 1:
The patent combines the adhesive function and electrical conduction function into a single integrated strip structure. The conductive components are embedded within the adhesive strip layers, merging what would traditionally be separate elements (adhesive bonding layer and electrical conductor) into one unified component that performs both functions simultaneously.
Solution Approach 2:
The adhesive strip is designed to perform multiple functions: mechanical bonding of components and electrical power supply/data transmission. By incorporating conductive components that extend through the adhesive layers, the strip becomes a multi-functional element that replaces both adhesive tape and separate wiring, allowing a single component to serve dual purposes.
2Adaptability or versatility
If conductive components are embedded in single-sided adhesive tape, then power can be supplied to some extent, but electrical connection in the z-direction is impossible
Solution Approach 1:
The patent transitions from single-sided to double-sided adhesive configuration, adding the z-dimension of conductivity. Conductive components are positioned to extend through the adhesive layers in the thickness direction, enabling electrical connection between opposing surfaces. This dimensional expansion allows the strip to provide electrical pathways perpendicular to the bonding surfaces, which was impossible with single-sided designs.
Solution Approach 2:
The conductive components are nested within the adhesive strip structure, with conductive elements embedded between and within the adhesive layers. This nesting arrangement allows the conductive components to be integrated into the adhesive construction without requiring separate external wiring, achieving z-direction conductivity while maintaining a compact, unified structure.
3Productivity
If manual soldering or plugging is used for power supply, then reliable electrical connection is achieved, but assembly time and labor costs increase
Solution Approach 1:
The conductive components are pre-integrated into the adhesive strip during manufacturing, establishing electrical pathways before the actual component assembly process. This preliminary preparation eliminates the need for on-site soldering or plugging operations, as the electrical connection infrastructure is already in place and ready to function immediately upon component bonding.
Solution Approach 2:
The adhesive strip performs self-service by providing both mechanical bonding and electrical connection functions simultaneously without requiring external assistance. The conductive components are positioned to automatically establish electrical contact with component pads or terminals during the adhesive bonding process, eliminating the need for separate manual electrical connection operations.
