Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a programmable laser device projects laser images continuously, then productivity is improved, but the device generates excessive heat causing reliability issues
Solution Approach 1:
The laser device operates in periodic cycles, alternating between active projection mode and cooling mode. The control circuit automatically switches the laser between these states based on operational timing, allowing the device to maintain productivity through repeated projection cycles while ensuring reliability by incorporating mandatory cooling periods to dissipate accumulated heat
2Ease of operation
If a control panel is added to enable programmability, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control panel is designed as a multi-functional integrated unit that combines multiple capabilities including program selection, timing control, and automatic cooling management. This universal control interface allows users to operate various laser projection functions through a single unified panel, improving ease of operation while the integrated design minimizes the increase in overall device complexity by consolidating control functions
Data Source
AI summary
A programmable laser device is configured to project a laser image, and includes an outer casing, a lens provided on a side surface of the outer casing, and a power switch that switches the programmable laser device between an ON state and an OFF state. A memory stores one or more programs, each including at least one laser image. A control panel has a control panel display that includes a keyboard having character buttons and a SEND button. A processor is configured to, when the programmable laser device is in the ON state, execute the one or more programs selected via the control panel. In addition, the programmable laser device includes a laser configured to display any one of the laser images of the one or more programs stored in the memory, and the laser image input via keyboard of the control panel.
