## Design & Technology: Lampshade Project Evaluation
*   **Objective:** Design and manufacture a functional, aesthetic lampshade for domestic use.
*   **Process:** Utilizes CAD/CAM and laser-cutting technology.

## Project Brief & Specification
*   **Problem:** Generic solutions lack sustainable materials and customization.
*   **Criteria:** Max height 200mm, must fit standard light fittings, include visual motifs for shadow play, and use laser-cut precision joinery.

## Iteration 1: Cardboard Prototype
*   **Test:** Validated 200mm height and surface motifs.
*   **Flaws:** Glued seams were unstable; material warped; lack of visual continuity.
*   **Score:** High cost efficiency but low stability and durability.

## Iteration 2: Refinement & Development
*   **Material:** Shifted to 3mm Laser-cut MDF/Plywood.
*   **Dimensions:** Standardized to 180mm (H) x 111mm (W).
*   **Joinery:** Evolved from simple finger joints to mechanical dovetail and dowel locks for superior stability.

## CAD/CAM Manufacturing
*   **Fabrication:** Parts cut from 3mm stock with focus on vector path accuracy and kerf management.
*   **Tolerances:** Precision engineering within ±0.5mm.
*   **Rationale:** Dovetail joints provide higher tensile strength and minimize the need for adhesive.

## Final Evaluation & Future Steps
*   **Results:** Significantly improved rigidity and professional appearance compared to Version 1.
*   **Improvements:** Future iterations will include high-quality veneers, in-line dimmer controls, and translucent inner layers for light diffusion.
