Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional waste removal devices are used, then waste can be removed, but the device requires both hands and is bulky making it difficult to carry and use while standing
Solution Approach 1:
The device is divided into distinct functional modules: a handle assembly, a telescoping rod with nested segments, a motor assembly, and a tine assembly. This segmentation allows each component to be optimized independently and simplifies the overall structure for one-handed operation while maintaining functionality.
Solution Approach 2:
The telescoping rod employs nested cylindrical segments that can extend and retract within each other, allowing the device to transition from a compact carried state to an extended operational state. This nesting principle reduces the device's footprint when not in use while providing sufficient length during operation.
2Weight of moving object
If conventional waste removal devices are used, then waste can be removed, but the device is bulky and non-retractable making it difficult to carry
Solution Approach 1:
The telescoping rod uses nested cylindrical segments that retract into each other, reducing the device's overall length from several feet when extended to a compact size when retracted. This enables easy carrying in a vehicle or home while maintaining operational length when needed.
Solution Approach 2:
The device transitions from a static, fixed-length structure to a dynamic, variable-length structure through the telescoping mechanism. The rod can be extended to the required length for waste removal and then retracted to a compact form for portability, adapting to different operational and storage conditions.
3Productivity
If conventional waste removal devices are used, then waste can be removed, but the device requires both hands making it inefficient
Solution Approach 1:
The device incorporates automatic functions including motor-driven tine extension and retraction, telescoping rod extension and retraction, and automatic bag deployment. These self-service features eliminate the need for manual manipulation of multiple components, allowing one-handed operation and improving operational efficiency.
Solution Approach 2:
Manual mechanical operations are replaced with motorized systems. DC motors drive the tine assembly extension and retraction, while electric motors control the telescoping rod extension and retraction. This substitution of mechanical systems with motorized systems reduces the physical effort and hand movements required during operation.
4Ease of operation
If conventional waste removal devices are used, then waste can be removed, but the device is difficult to use for individuals with physical limitations
Solution Approach 1:
Manual mechanical operations requiring significant physical effort are replaced with motorized systems. The motor assembly automatically extends and retracts the tines, and the telescoping mechanism electrically extends and retracts the rod, eliminating the need for users to exert force for these operations.
Solution Approach 2:
The device performs operations automatically without requiring user physical effort. The motorized components self-actuate to extend and retract the working parts, and the telescoping rod automatically adjusts its length, making the device accessible to individuals with limited physical strength or mobility.
