5.1 JUSTIFICATION FOR THE SCORES GIVEN

Design No.	Objective	Score Allocated	Justification for the Score
	Aesthetics	-8	Less visually appealing due to exposed mechanical parts
	Ease of Use	14	Simple manual operation makes it user-friendly
2 - N	Portability	5	Moderate portability with lightweight components
	Maintenance	0	Standard maintenance requirements
	Cost	6	Uses cost-effective components with moderate pricing
	Accuracy	9	Delivers a reasonably accurate sine wave output
	Aesthetics	4	Better casing and design will make it more presentable
	Ease of Use	14	User-friendly mechanism with smooth operation
1 - S	Portability	0	Bulky design reduces portability
	Maintenance	-6	Requires frequent maintenance due to complex mechanisms
	Cost	6	Moderate cost due to specialized parts
	Accuracy	18	High accuracy in sine wave generation due to precise movement
	Aesthetics	8	Improved design and well-structured layout ,well defined structure
	Ease of Use	7	Some complexity in handling but still manageable
3 - B	Portability	10	Compact and easy to transport.
	Maintenance	-6	Requires periodic maintenance since along with wave generating unit car components must also be handled.
	Cost	-12	Expensive due to high-end materials
	Accuracy	0	It can create decently accurate waves as that of datum
	Aesthetics	0	Standard look with no extra design improvements
	Ease of Use	0	No added features to enhance usability
4-V	Portability	0	Not designed for easy movement
	Maintenance	0	No major maintenance issues or requirements
	Cost	0	Neutral cost due to balance in components
	Accuracy	0	Standard accuracy
