Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If actuation modules are pre-assembled at the factory, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The lifting table stand is divided into modular components: a standardized base structure with mounting interfaces, and separate interchangeable actuation modules. The beam includes standardized receiving members that can accept different actuation module types (electric motors, manual cranks, control boxes) without requiring custom assembly at the factory, thus maintaining manufacturing precision while enabling user adaptability.
Solution Approach 2:
The base structure is designed with universal mounting interfaces and standardized receiving members on the beam that can accommodate multiple types of actuation modules. This universal design allows a single base structure to support various actuation module types (electric, manual, wireless-controlled), resolving the contradiction between standardized manufacturing and user customization needs.
2Device complexity
If actuation modules are fixed at the factory, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The system transitions from a static, fixed configuration to a dynamic, reconfigurable system. The receiving members on the beam are designed to accept and release different actuation module types through simple attachment mechanisms, allowing users to easily change the system configuration based on their needs without complex reassembly procedures.
Solution Approach 2:
Standardized receiving members act as intermediaries between the base structure and various actuation modules. These receiving members provide a standardized interface that simplifies the connection process, allowing users to easily attach or detach different module types without dealing with the complexity of direct integration into the base structure.
3Adaptability or versatility
If multiple actuation module types are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The base structure and beam are designed with universal mounting interfaces and standardized receiving members that can accommodate multiple types of actuation modules (electric motors, manual cranks, wireless-controlled modules). This universal design enables compatibility with different module types without requiring multiple specialized base structures, thus improving adaptability while controlling structural complexity.
Solution Approach 2:
The system uses standardized interface parameters (mounting hole patterns, connection mechanisms, mounting positions) that remain constant across different actuation module types. By maintaining consistent interface parameters while allowing variation in actuation mechanism parameters, the system achieves multi-type compatibility without proportionally increasing structural complexity.

AI summary
A lifting table stand includes a pair of telescopic columns, a carrier, an actuation module and a passive mechanism. Each telescopic column includes multiple tubes adapted to sheathe with each other and move telescopically relative to each other. The carrier includes a beam straddling the telescopic columns and a pair of support members perpendicularly connected to two ends of the beam. The actuation module includes a receiving member detachably installed to the beam and a driver connected to the receiving member. The passive mechanism includes a transmission shaft and a pair of gear sets installed in the tubes. The transmission shaft passes the driver and is connected to each gear set. Since the receiving member is detachably installed to beam, the actuation module may be changed to different types to control the elevation of the lifting table stand.
