Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-direction self-leveling mechanism is used, then the device structure is simple, but the versatility and effectiveness in various applications is limited
Solution Approach 1:
The patent transitions from single-direction leveling to multi-directional leveling by adding a second bearing that operates transversely to the first bearing. This enables the chassis to pivot in at least two different directions (first direction and second direction), effectively adding dimensional capability to the self-leveling mechanism and resolving the contradiction between simplicity and versatility.
2Measurement precision
If a multi-directional self-leveling mechanism is used, then the accuracy and versatility are improved, but the device complexity increases
Solution Approach 1:
The self-leveling mechanism is segmented into multiple independent bearing components, each responsible for a specific direction of pivoting. The first bearing handles pivoting in a first direction while the second bearing handles pivoting in a second direction. This segmentation allows each component to maintain simplicity while the combination achieves multi-directional accuracy.
Solution Approach 2:
By introducing a second bearing that operates transversely to the first bearing, the system gains the ability to pivot in multiple directions simultaneously. This dimensional expansion enables true multi-directional self-leveling, improving accuracy without requiring a completely redesigned mechanism.
3Adaptability or versatility
If a pendulum-type device is used for single-direction leveling, then the mechanism is simple and reliable, but it cannot provide self-leveling in multiple directions
Solution Approach 1:
The patent merges multiple pendulum-type bearing mechanisms into a single integrated chassis system. The first bearing and second bearing are both mounted on the chassis, allowing it to pivot in multiple directions simultaneously. This combining approach maintains the reliability of simple pendulum mechanisms while achieving multi-directional self-leveling capability.
Solution Approach 2:
The chassis is designed to serve multiple functions: it carries the light source, enables pivoting in multiple directions through the bearing assembly, and provides self-leveling capability. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in overall mechanism complexity while enhancing self-leveling capability.
