Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hard drive is shredded to ensure data cannot be extracted, then data security is improved, but device complexity and cost increase
Solution Approach 1:
The hard drive is divided into multiple fragments through compression between grooved plates and forced bending, ensuring data cannot be recovered from individual pieces. This segmentation approach achieves data security without requiring complex shredding machinery.
Solution Approach 2:
The patent replaces complex mechanical shredding systems with a simpler compression and bending mechanism using hydraulic or pneumatic actuation. This substitution maintains data destruction effectiveness while significantly reducing device complexity.
2Reliability
If traditional shredding equipment is used to destroy hard drives, then data security is improved, but noise and maintenance requirements worsen
Solution Approach 1:
The patent replaces noisy mechanical shredding with a quieter compression and bending process using hydraulic or pneumatic actuators. This substitution eliminates the high noise levels associated with traditional shredders while maintaining data destruction effectiveness.
3Reliability
If complex shredding equipment is deployed to ensure complete data destruction, then data security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces complex shredding equipment with a simple compression and bending system that can be operated by unskilled personnel. The use of hydraulic or pneumatic actuators with basic control mechanisms significantly improves ease of operation while maintaining data security.
4Device complexity
If compression and bending is used to fragment the memory disk, then device complexity is reduced, but the effectiveness of data destruction must be ensured
Solution Approach 1:
The compression plates incorporate grooves that force the hard drive platters to bend and fragment into multiple pieces during compression. This segmentation ensures data cannot be recovered even though the overall device complexity is reduced.
Solution Approach 2:
The compression plates feature localized grooves and surface features that concentrate stress at specific points, ensuring reliable fragmentation of the platters. This local quality enhancement maintains data destruction effectiveness while keeping the overall apparatus simple.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively destroys hard drives by compressing and bending them, ensuring that data cannot be recovered, while being simple to operate and safe for use in offices without the need for specialized equipment or skilled operators.
Implementation Method 1
The drive apparatus includes a linearly movable member and is coupled to a control system to selectively control movement of the member. The movable member can be part of a hydraulic cylinder with a movable ram.
Implementation Method 2
The face on the movable plate has a cavity partially defined by a rib. A second plate is carried by the support assembly and has an exposed second face facing generally toward the first face, The second plate has at least one protuberance projecting therefrom that is sized and shaped to fit within a respective cavity.
