Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual operation is used for tilting windows, then the device complexity is reduced and ease of manufacture is improved, but the productivity decreases and labor intensity increases
Solution Approach 1:
The patent replaces the manual mechanical operation system with an electric motorized system. The motorized drive unit includes an electric motor, worm gear, and drive shaft that automatically tilt the window sash, eliminating the need for manual cranking and significantly improving productivity while reducing labor intensity.
Solution Approach 2:
The motorized system enables the window to tilt automatically without human intervention. The electric motor self-actuates the window tilting operation through the worm gear mechanism, making the system self-serving and eliminating the need for continuous manual operation.
2Ease of operation
If motorized drive units are added to existing manual window operators, then the productivity and convenience are improved, but the device complexity increases
Solution Approach 1:
The patent combines the motorized drive unit with the existing manual window operator system. The electric motor, worm gear, and drive shaft are integrated into a compact assembly that merges with the manual operator components, creating a unified system that maintains simplicity while adding motorized functionality.
Solution Approach 2:
The motorized drive unit is designed to be universally compatible with various manual window operator types. The standardized interface and mounting system allow the same motorized unit to replace or augment different manual operator configurations, reducing overall system complexity through standardization.
3Object-affected harmful factors
If a cover is added to enclose the motorized drive units and window frame section, then the aesthetic appearance and light blocking are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent uses a cover made from extruded aluminum or plastic material that forms a thin-walled enclosure. This thin-film approach provides effective light blocking and aesthetic coverage while maintaining manufacturing simplicity through extrusion processes, avoiding the need for complex multi-component assemblies.
Solution Approach 2:
The cover is constructed from composite or alloy materials such as extruded aluminum or fiberglass-reinforced plastic. These composite materials provide structural strength, light blocking properties, and aesthetic appearance simultaneously, eliminating the need for separate structural and cosmetic components.
