Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing drilling machines are modified to create inclined holes, then the capability to drill inclined holes is improved, but the machine complexity and production cost increase significantly
Solution Approach 1:
The drilling machine employs a movable spindle holder that can be adjusted to different inclination angles dynamically. The spindle holder can be positioned at various angles relative to the panel surface, allowing the machine to adapt to different drilling requirements without permanent modifications. This dynamic adjustability resolves the contradiction by providing versatility while maintaining operational simplicity through movable rather than fixed complex mechanisms.
Solution Approach 2:
The drilling machine is designed with a universal spindle holder that can perform both perpendicular and inclined drilling operations. The same spindle holder structure serves multiple functions by simply changing its angular position, eliminating the need for separate specialized drilling mechanisms. This multi-functionality approach improves adaptability while avoiding the complexity of multiple dedicated systems.
2Adaptability or versatility
If existing drilling machines are modified to create inclined holes, then the capability to drill inclined holes is improved, but the production cost increases
Solution Approach 1:
The movable spindle holder with adjustable inclination angles allows the machine to be manufactured once and reused for both perpendicular and inclined drilling. This dynamic capability eliminates the need for costly permanent modifications or multiple specialized machines, thereby improving adaptability while keeping production costs low through a single versatile unit.
Solution Approach 2:
The universal spindle holder design allows one machine to replace multiple specialized drilling machines. By making the spindle holder capable of both perpendicular and inclined operations, the invention reduces the need for purchasing and maintaining separate equipment, thereby reducing overall production costs while improving versatility.
3Adaptability or versatility
If existing drilling machines are modified to create inclined holes, then the capability to drill inclined holes is improved, but the production time and downtime increase
Solution Approach 1:
The movable spindle holder can be quickly repositioned between perpendicular and inclined positions without requiring machine stops or extensive reconfiguration. This dynamic adjustability allows operators to switch between drilling modes rapidly, improving versatility while minimizing production time losses compared to fixed modification approaches.
4Ease of operation
If perpendicular holes are drilled in panels, then the assembly is simpler initially, but the coupling loosens over time reducing durability
Solution Approach 1:
The invention changes the angular parameter of the drilled holes from perpendicular (0°) to inclined angles (typically 15°-45°). This parameter change in hole inclination improves coupling durability and resistance to loosening while the adjustable spindle holder maintains ease of operation by allowing quick adjustment to the required angle for optimal performance.
