Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional machine-readable elements and visual information are used on transactional cards, then the cards maintain simplicity and low cost, but they lack sensory features to enhance desirability and individualization
Solution Approach 1:
The patent combines multiple sensory features (light-emitting LEDs, sound-producing speakers, heat-sensitive materials, and scent-releasing materials) into a single transactional card structure. This merging of diverse functional elements into one integrated device enables the card to provide visual, auditory, tactile, and olfactory sensory experiences simultaneously, resolving the contradiction between enhancing adaptability through sensory features and maintaining structural simplicity.
Solution Approach 2:
The transactional card is designed with multi-functionality by incorporating circuitry that can produce light, sound, and heat, along with materials that release scents. These universal sensory components can be activated in various combinations to create different sensory experiences, allowing the card to adapt to different user preferences and scenarios while maintaining a unified card structure.
2Adaptability or versatility
If sensory features such as light, sound, and scent are added to transactional cards, then desirability and individualization are enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent segments the sensory features into distinct modular components: light-emitting circuitry with LEDs, sound-producing circuitry with speakers, heat-sensitive materials, and scent-releasing materials. Each component can be independently manufactured and then assembled into the final card, simplifying the overall manufacturing process while enabling high levels of individualization and customization.
Solution Approach 2:
The patent utilizes heat-sensitive materials that change their properties (color or scent release) in response to temperature changes. This parameter-based approach allows for dynamic sensory responses without requiring complex active control systems, simplifying manufacturing while enabling rich sensory experiences that enhance individualization and user engagement.
3Adaptability or versatility
If circuitry for producing light and sound is incorporated into transactional cards, then sensory experience is enriched, but energy consumption increases
Solution Approach 1:
The patent implements periodic activation of the light and sound circuitry rather than continuous operation. The circuitry is triggered by specific events such as card insertion, swiping, or user interaction, producing sensory outputs only when needed. This periodic action pattern significantly reduces overall energy consumption while maintaining rich sensory experiences during active use.
Solution Approach 2:
The patent employs heat-sensitive materials that passively respond to temperature changes without requiring active energy input. When the card is handled or exposed to heat, these materials automatically change color or release scents, providing sensory feedback with minimal energy consumption compared to actively powered sensory components.
