Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If active electronic components are added to the stylus to enable signal transmission, then input functionality is improved, but the stylus thickness increases making it too thick to store inside the computing device
Solution Approach 1:
The stylus is divided into functional segments: the body containing electronic components for input functionality, and a separate retention mechanism with arms that enable storage. This segmentation allows the stylus to maintain input capabilities while the retention mechanism provides a compact storage solution when the stylus is not in use.
Solution Approach 2:
The retention mechanism with its arms is designed to nest the stylus within or alongside the computing device. The L-shaped or other shaped arms create a compact configuration that reduces the overall space required for storage, effectively nesting the stylus into the device profile.
2Productivity
If the stylus is designed with a retention mechanism for secure attachment, then storage efficiency is improved, but the device complexity increases
Solution Approach 1:
The retention mechanism serves multiple functions: it secures the stylus to the computing device for storage, provides electrical connection for charging the battery, and enables easy attachment and release. This multi-functionality reduces the need for separate mechanisms for each function, thereby managing complexity while improving storage efficiency.
Solution Approach 2:
The retention mechanism combines the mechanical retention function with the electrical charging function by integrating the electrically conductive contact into the same structure. This merging of functions reduces the number of separate components needed, managing device complexity while achieving secure attachment and power transfer.
3Use of energy by moving object
If the stylus includes a rechargeable battery, then power management is improved, but the stylus volume increases
Solution Approach 1:
The stylus is equipped with a rechargeable battery that can be recharged while stored in the computing device. This preliminary charging action ensures the stylus is always ready for use without requiring external charging, improving power management while the battery is integrated into the existing stylus volume constraints.
4Power
If the retention mechanism includes an electrically conductive contact for charging, then power transfer capability is improved, but the mechanism complexity increases
Solution Approach 1:
The electrically conductive contact is merged with the retention mechanism arms, combining the mechanical retention function with the electrical charging function in a single integrated structure. This reduces the need for separate charging components and simplifies the overall design while maintaining power transfer capability.
Solution Approach 2:
The retention mechanism is designed to perform multiple functions simultaneously: mechanical retention of the stylus and electrical charging through the conductive contact. This multi-functionality improves power transfer capability while managing complexity by using a single mechanism for both purposes.
