Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If suction power is continuously maintained at high level, then cleaning efficiency is improved, but energy consumption increases
Solution Approach 1:
The suction power is made dynamically adjustable based on real-time detection of operation angle. The controller modifies the suction source output according to whether the cleaner is in optimal cleaning position, transitioning between high and low power states to match actual cleaning needs.
Solution Approach 2:
An operation angle sensor continuously monitors the cleaner's angle relative to the surface and provides feedback to the controller. This feedback loop enables automatic adjustment of suction power, ensuring high efficiency only when properly positioned while reducing power consumption during improper use or transport.
2Productivity
If operation angle sensor and controller are added, then suction optimization is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical angle adjustment mechanisms with an electronic sensing and control system. The operation angle sensor and controller electronically detect and adjust suction parameters, eliminating the need for mechanical angle indicators or manual adjustment mechanisms.
Solution Approach 2:
The system optimizes cleaning performance by dynamically changing the suction power parameter based on detected operation angle. This parameter adjustment approach simplifies the overall system compared to mechanical modifications, using electronic control to achieve optimal cleaning conditions.

AI summary
A handheld cleaner (10) includes a housing (14) that at least partially defines an air pathway (18) and a suction nozzle (22) that defines a nozzle inlet (26) in communication with a suction pathway (30). The suction pathway (30) is configured to extract at least one of debris or liquid from a surface (5) to the air pathway (18). An exhaust (34) defines an outlet to the air pathway (18). A suction source (38) is in fluid communication with the suction nozzle (22) via the suction pathway (30). The suction source (38) is configured to generate a working air stream. An operation angle sensor (42) is configured to detect an operation angle of the handheld cleaner (10) relative to the surface (S). A controller (46) is in electrical communication with the suction source (38) and the operation angle sensor (42) via an electrical pathway. The controller (46) is configured to control an amount of suction generated by the suction source (38) based on the detected operation angle.
