Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrically-driven sanitizer or disinfectant supply apparatuses fail to meet user needs as they supply sanitizers or disinfectants in a fixed amount, not allowing for variable user requirements.
Innovation Solution
A cleaning agent supply device with a radian-adjustable fan-shaped light-blocking unit, a photosensitive counting unit, and a count control unit that allows users to control the number of times the cleaning agent is squeezed by adjusting the rotation angle of the rotary driving unit, enabling customizable dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electrically-driven sanitizer or disinfectant supply apparatuses are used, then the cleaning agent can be supplied automatically, but the amount supplied is fixed and cannot be adjusted to variable user needs
Solution Approach 1:
The patent applies the dynamics principle by making the light-blocking unit radian-adjustable, allowing the system to dynamically change its light-blocking angle. This enables the photosensitive counting unit to detect different numbers of light-blocking events, thereby controlling the number of reciprocating squeezes of the cleaning agent pump. The radian-adjustable mechanism transforms a static system into a dynamic one that can adapt to variable user needs for cleaning agent dispensing quantities.
2Adaptability or versatility
If a radian-adjustable fan-shaped light-blocking unit with photosensitive counting unit is added, then the number of times cleaning agent is squeezed can be controlled, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical control mechanisms with an optical control system. Instead of using mechanical counters or complex electronic controllers, the invention uses a photosensitive counting unit that optically detects the radian-adjustable fan-shaped light-blocking unit's rotation. This optical detection method simplifies the control system by using light interaction rather than complex mechanical or electronic counting mechanisms, thereby reducing overall device complexity while achieving precise control over squeezing times.
Solution Approach 2:
The patent introduces a light-blocking unit as an intermediary element that mediates between the rotary driving unit and the photosensitive counting unit. This intermediary converts rotational motion into detectable light-blocking events, enabling the photosensitive sensor to count the number of rotations and control the squeezing times accordingly. The intermediary element simplifies the control architecture by providing a clear, detectable signal mechanism.
