Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional printing and drilling methods are used on overhead surfaces, then operators can perform the work with basic tools, but the process becomes labor-intensive, time-consuming, and hazardous requiring auxiliary means
Solution Approach 1:
The patent combines laser printing and drilling functions into a single integrated system mounted on a scissor lift. The system merges target marking and hole drilling operations that were previously performed separately, allowing both functions to be executed from one platform by one operator, thereby improving ease of operation while maintaining productivity
Solution Approach 2:
The scissor lift acts as an intermediary platform that elevates the operator and equipment to overhead working surfaces. This mediator eliminates the need for operators to work from ground level using extended tools, providing direct access to ceiling surfaces and making overhead work as easy to operate as ground-level work
2Adaptability or versatility
If auxiliary means such as ladders and scissor platforms are used, then operators can access overhead surfaces, but the device complexity increases and safety risks arise
Solution Approach 1:
The scissor lift platform is designed to be universal, capable of supporting both laser printing equipment and drilling equipment, as well as accommodating different operator positions and tool configurations. This multi-functionality allows the same platform to handle various overhead tasks without requiring specialized equipment for each function, reducing overall device complexity while maintaining adaptability
Solution Approach 2:
The scissor lift provides dynamic height adjustment and positional flexibility, allowing the platform to adapt to different ceiling heights and working locations. This dynamic capability enables the system to handle varied overhead surfaces without requiring multiple fixed platforms or complex reconfiguration, simplifying the overall device structure while maintaining versatility
3Ease of operation
If manual printing and drilling operations are performed on ceiling surfaces, then flexibility in positioning is maintained, but the process becomes monotonous and laborious
Solution Approach 1:
The system incorporates self-positioning capabilities where the laser target automatically marks the precise drilling location without requiring manual measurement and transfer of coordinates. The laser guides the drilling operation automatically, allowing the equipment to serve itself in terms of positioning and alignment, thereby reducing operator labor and time consumption while maintaining ease of operation
