Design and Technology – Design process | e-Consult

The feedback received from the user testing is critical for refining the design of the shelf-accessing device. The feedback highlights three key areas for improvement: ease of operation, weight, and aesthetics. The student needs to address each of these issues systematically, considering both the practical and user experience aspects of the design.

Ease of Operation: The feedback that the device is difficult to operate suggests that the user interface (e.g., levers, buttons, handles) needs to be redesigned. The student should consider:

• Ergonomics: Designing the controls to be easily accessible and operable by individuals with limited strength or dexterity.
• Intuitive Design: Using clear visual cues and simple mechanisms to guide the user.
• Reduced Effort: Minimizing the amount of force required to operate the device.

Weight: The device being too heavy to maneuver is a significant usability issue. The student should explore:

• Material Selection: Using lighter materials (e.g., aluminum, composites) without compromising strength and durability.
• Structural Optimization: Redesigning the structure to reduce material usage while maintaining structural integrity.
• Leverage: Incorporating features that provide leverage to reduce the effort required to lift and position the device.

Aesthetics: The feedback regarding the device's visual unappealing nature is subjective but important. The student should consider:

• Form Follows Function: Integrating aesthetic considerations into the design process from the outset, rather than as an afterthought.
• User Preferences: Gathering feedback on aesthetic preferences from potential users.
• Color and Finish: Choosing colors and finishes that are visually appealing and appropriate for a home environment.

The student should use a combination of design principles, such as:

• User-Centered Design: Prioritizing the needs and preferences of the users throughout the design process.
• Iterative Design: Making incremental improvements to the design based on feedback and testing.
• Prototyping: Creating and testing multiple prototypes to evaluate different design options.

By systematically addressing each of these issues and applying appropriate design principles, the student can refine the design of the shelf-accessing device to create a more user-friendly, practical, and aesthetically pleasing product.
