Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional secondary battery technologies are used, then energy storage capability is achieved, but user convenience and integration with fabric products is insufficient
Solution Approach 1:
The patent employs a flexible encapsulator made of thin film material that can conform to fabric surfaces and wearable devices. This flexible structure allows the battery to be integrated into clothing and accessories while maintaining its energy storage function, directly resolving the contradiction between ease of operation and adaptability to fabric products.
Solution Approach 2:
The battery is divided into modular components including the flexible encapsulator, battery cell, and separate attachment mechanism (Velcro). This segmentation allows the battery to be easily attached and detached from different fabric products, enhancing both user convenience and versatility across various wearable applications.
2Reliability
If fixed attachment methods are used, then secure positioning is achieved, but ease of attachment and detachment is reduced
Solution Approach 1:
The patent transitions from fixed, permanent attachment to a dynamic, reversible attachment system using Velcro. This allows the battery to be securely positioned during use while enabling easy attachment and detachment when needed, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The attachment function is separated from the battery body as a distinct modular component (Velcro strip). This segmentation enables independent optimization of attachment security and ease of operation, allowing the battery to be reliably secured during use while maintaining simple attachment and detachment processes.
3Ease of operation
If symmetrical attachment design is used, then ease of attachment is improved, but incorrect polarity connection cannot be prevented
Solution Approach 1:
The patent introduces asymmetry in the Velcro attachment design where the orientation of the Velcro strip or its positioning relative to the battery terminals creates a unique attachment direction. This asymmetric design guides users to attach the battery in the correct orientation, preventing reverse polarity connections while maintaining ease of attachment through the simple Velcro mechanism.
Solution Approach 2:
The Velcro attachment mechanism serves as an intermediary between the user and the battery terminals. By positioning this intermediary element asymmetrically, it mediates the attachment process to naturally guide correct polarity alignment before electrical connection is established, resolving the contradiction between ease of operation and reliability.
