Innovation Solution
A cup attaching apparatus with a white LED illumination source that includes a light intensity control system allowing adjustable light intensity through a rotary knob and a control section to match lens transmittance, and a gradual turn-on feature to reduce eye strain, using a combination of a condenser and resistor to delay light intensity increase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If white LED is used as illumination light source, then lamp life is extended and cost is reduced, but visibility of lens image deteriorates due to unbalanced wavelength emission
Solution Approach 1:
The patent introduces a light intensity adjusting device that allows operators to modify the illumination intensity parameters of the white LED to match different lens transmittance characteristics. This resolves the contradiction by enabling parameter optimization for both visibility and energy efficiency without changing the fundamental LED light source.
Solution Approach 2:
The patent implements dynamic light intensity adjustment capability, allowing the illumination intensity to be changed during operation based on lens requirements. This transforms the static LED output into a dynamically adjustable system that can adapt to different lens types and operator needs, resolving the visibility issue while maintaining LED longevity.
2Illumination intensity
If light intensity of white LED is increased to enhance visibility with colored lens, then visibility improves, but glare occurs causing burden on operator's eyes
Solution Approach 1:
The light intensity adjusting device enables precise control of illumination parameters, allowing operators to select optimal intensity levels that provide sufficient visibility for colored lenses without excessive intensity that would cause glare. This parameter optimization resolves the contradiction between visibility enhancement and glare prevention.
3Speed
If white LED is turned on immediately to full intensity, then operation speed is improved, but eye strain increases due to sudden light intensity increase
Solution Approach 1:
The patent implements a gradual light intensity increase function that activates when the apparatus detects dark environmental conditions. This preliminary action slowly ramps up the light intensity to a comfortable level before reaching full brightness, preventing sudden eye strain while still achieving full operational intensity efficiently.
4Illumination intensity
If light intensity is continuously high to ensure visibility, then visibility is maintained, but energy consumption increases
Solution Approach 1:
The light intensity adjusting device allows operators to optimize illumination parameters based on actual working conditions and lens transmittance. This enables energy-efficient operation by using only the necessary light intensity level required for each specific task, rather than continuously operating at maximum intensity.
