Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex lifting mechanism with electric motors and linkage transmission systems is used, then the treadmill achieves diversified slope adjustments, but the manufacturing cost increases, maintenance difficulty increases, and energy consumption increases
Solution Approach 1:
The patent extracts and removes the complex electric lifting mechanism, linkage transmission system, and control system from the treadmill structure. Instead, it uses a simple manual lifting rod with positioning holes that can be directly inserted into different positions on the frame to achieve slope adjustment. This extraction of unnecessary complex components directly reduces device complexity while maintaining the core function of slope adjustment.
Solution Approach 2:
The patent employs simple, inexpensive components such as a basic lifting rod with positioned holes and corresponding positioning structures on the frame. These simple components replace expensive electric motors and complex transmission mechanisms. The design prioritizes simplicity and low cost over sophisticated adjustable mechanisms, aligning with the principle of using simple, affordable solutions.
2Adaptability or versatility
If a complex lifting mechanism is used, then slope adjustment functionality is achieved, but manufacturing cost increases
Solution Approach 1:
The lifting rod is segmented with multiple positioning holes at different heights and angles. Each hole represents a discrete slope position. This segmentation allows the simple rod to provide multiple slope adjustment options without requiring complex continuous adjustment mechanisms. The segmented design achieves versatility through discrete positions rather than continuous mechanical systems.
Solution Approach 2:
The patent uses inexpensive, simple components including a basic lifting rod, positioning holes, and corresponding positioning structures on the frame. These simple elements replace costly electric motors, transmission systems, and control electronics. The manufacturing cost is significantly reduced while maintaining the essential slope adjustment functionality through this simplified approach.
3Adaptability or versatility
If a complex lifting mechanism is used, then lifting action is achieved, but energy consumption increases
Solution Approach 1:
The lifting rod is designed to be manually operated by the user directly. The user inserts the rod at different positions to achieve slope adjustment without requiring external power sources. The system serves itself through direct manual input, eliminating the need for electric motors and energy-consuming transmission systems. The user's physical effort replaces electrical energy consumption.
4Adaptability or versatility
If a complex lifting mechanism is used, then slope adjustment is achieved, but overall stability and convenience are affected
Solution Approach 1:
The lifting rod combines multiple functions into a single component: it serves as both the lifting mechanism and the positioning mechanism. The positioning holes and corresponding structures on the frame are integrated directly into the basic rod design. This merging of functions into a simple unified structure improves stability by eliminating the instability introduced by complex, multi-component mechanical systems with multiple connection points and potential failure modes.
