Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing raising and lowering devices are used, then lifting function is provided, but device complexity increases and loading area is limited
Solution Approach 1:
The device is divided into two independent beams (first beam and second beam) that can move separately along the profile element. Each beam is connected through individual struts to the profile element, allowing them to be segmented and moved independently, thus reducing overall device complexity while maximizing loading area utilization.
Solution Approach 2:
The beams move along the profile element in a dimensional path that utilizes the entire loading surface area. The profile element serves as a guide rail that defines the movement dimension, allowing the beams to access different positions across the loading area without interfering with each other, thereby maximizing the usable loading space.
2Reliability
If existing raising and lowering devices are used, then lifting function is provided, but risk of objects falling increases
Solution Approach 1:
The synchronizing element provides feedback control by ensuring that the first and second beams move in a coordinated manner. The closed-loop mechanism around the profile element monitors and maintains the relative positions of the beams, preventing uncontrolled movement that could cause objects to fall, while keeping the control mechanism relatively simple.
Solution Approach 2:
The device incorporates damping mechanisms that provide beforehand cushioning to control the movement speed and deceleration of the beams. This prevents sudden movements or dropping of objects by dissipating kinetic energy before it can cause harm, enhancing safety without requiring complex active control systems.
3Reliability
If synchronized movement is implemented, then safety is improved, but device complexity increases
Solution Approach 1:
The synchronizing element acts as an intermediary mechanism that coordinates the movement of the first and second beams. By introducing this intermediate component that engages with the profile element, the beams are synchronized without requiring complex electronic control systems, maintaining relatively simple device architecture while achieving reliable synchronized movement.
