Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional transmission unit with belt is used, then the device can transmit motion, but the belt requires frequent replacement and increases maintenance needs
Solution Approach 1:
The patent replaces the belt-based mechanical transmission system with a direct gear engagement system. The drive gear on the wheel axle directly meshes with the transmission gear, eliminating the belt component entirely. This substitution resolves the maintenance issue by removing the belt that required frequent replacement, while maintaining effective motion transmission from the wheel to the counter.
2Ease of manufacture
If numerous parts are used in the transmission unit, then the transmission function can be achieved, but the manufacturing cost increases and assembly time is extended
Solution Approach 1:
The patent merges multiple transmission components into a simplified gear train system. Instead of using separate belts, pulleys, and tensioning mechanisms, the invention combines the transmission function into direct gear engagements between the wheel axle gear and the counter gear through a series of intermediate gears. This merging of functions reduces the total number of parts while maintaining the transmission capability, thereby lowering manufacturing costs and assembly time.
Solution Approach 2:
The patent extracts and removes unnecessary components from the transmission system. By eliminating the belt, pulleys, and associated tensioning devices, the invention keeps only the essential gear elements required for motion transmission. This extraction of redundant parts simplifies the overall structure, reduces manufacturing complexity, and decreases assembly time while preserving the core transmission function.

AI summary
A distance measuring wheel device includes a base and a counter is arranged inside the base and laterally connected to the axle of a first gear. Two connection arms respectively extend from the base. The wheel is rotatably between the two connection arms. Each end of the axle of the wheel is rotatably connected with one end of each connection arm opposite to the base. A first chain gear is connected to the axle of the wheel corresponding to the first gear. A second gear is rotatably arranged at one side of the base and engaged with the first gear. A third gear is coaxially linked to the second gear. A fourth gear is engaged with the third gear. The second chain gear is coaxially linked to the fourth gear. The chain is surrounded and engaged with the first chain gear and the second chain gear.
