Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a spindle-type mechanical system is used for height adjustment, then the structure is simple and easy to manufacture, but significant manual effort is required and the adjustment process generates audible noise
Solution Approach 1:
The patent replaces the traditional manual spindle-type mechanical system with an electric motor-driven system. The motorized adjustment mechanism eliminates the need for manual operation of complex spindles, reducing the effort required by the user while maintaining the structural simplicity needed for ease of manufacture.
Solution Approach 2:
The patent introduces an electric motor as an intermediary between the user's control input and the height adjustment mechanism. This intermediary converts electrical energy to mechanical motion, automating the adjustment process and eliminating the direct manual effort previously required to operate spindle systems.
2Device complexity
If a spindle-type mechanical system is used for height adjustment, then the structure is simple, but audible noise is generated during adjustment
Solution Approach 1:
The patent replaces the noise-generating manual spindle mechanism with a motorized system that operates more quietly. The electric motor-driven adjustment mechanism reduces audible noise during height adjustment, making it suitable for environments where quiet operation is important, while maintaining acceptable device complexity.
3Ease of operation
If a motorized and automated height adjustment system is implemented, then ease of operation is improved and noise is minimized, but device complexity increases
Solution Approach 1:
The patent applies motorization to replace complex manual adjustment mechanisms, improving ease of operation. By using an electric motor with a simple control interface, the system achieves automated height adjustment that is easy to operate while managing device complexity through the selection of appropriate motor and control components.
4Ease of repair
If manual spindle adjustment is used, then the system is easy to assemble and disassemble, but significant manual effort and time are required for adjustment
Solution Approach 1:
The patent replaces manual spindle adjustment with a motorized system that performs height adjustment automatically and quickly. The motorized mechanism reduces the time required for adjustment from manual operation to automated motion, while the modular design maintains ease of assembly and disassembly for repair purposes.

AI summary
The invention relates to an improved height-adjustable bench, comprising a seat with an adjustable useful height, and furthermore, two spindles mechanically linked to corresponding scissor lift mechanisms, a geared motor and two connecting rods each mechanically linked to each of the spindles, and being fastened and articulated on the platen for fastening the scissor lift to the bench itself; the scissor lift mechanisms being arranged such that they provide the capacity to adjust the useful height of the seat of the bench, and each of the spindles being mechanically linked to the geared motor, receiving a concentric rotating movement with the axial shaft thereof; the rotating movement of the spindles causing a linear movement of the connecting rods in relation to the spindles, and the same rotating movement of the spindle causes a vertical displacement which is transmitted to the scissor lift mechanism and from said mechanism to the seat.
