Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-angle calibration bracket is used, then the structure is simple and stable, but it cannot adjust angles flexibly to meet special calibration requirements
Solution Approach 1:
The calibration bracket transforms from a fixed structure to a dynamic adjustable structure by introducing a support rod that can rotate relative to the base through a hinge connection, and a hanger that can move along the support rod and rotate at its connection point. This enables the calibration element to achieve multi-directional angle adjustment while maintaining structural simplicity through standardized mechanical components.
Solution Approach 2:
The calibration bracket is divided into independent functional modules: a base for stability, a support rod for angular adjustment, a hanger for positioning, and a calibration element. Each module can be adjusted independently, allowing flexible angle configuration without requiring complex integrated mechanisms, thus resolving the contradiction between adaptability and structural complexity.
2Adaptability or versatility
If a movable and adjustable calibration bracket is introduced, then angle flexibility is improved, but the device complexity increases
Solution Approach 1:
The calibration bracket transforms from a fixed structure to a dynamic adjustable structure by introducing a support rod that can rotate relative to the base through a hinge connection, and a hanger that can move along the support rod and rotate at its connection point. This enables the calibration element to achieve multi-directional angle adjustment while maintaining structural simplicity through standardized mechanical components.
Solution Approach 2:
The support rod acts as an intermediary component between the fixed base and the movable hanger, providing a rotational axis that simplifies the mechanism. The hinge shaft on the base serves as an intermediary that enables controlled rotation, and the universal ball in the hanger acts as an intermediary for multi-directional adjustment. These intermediary elements reduce overall system complexity by breaking down the adjustment function into simple, standardized mechanical interactions.
