Illuminated Card Insertion Structure for Easier Reader Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card insertion parts for card readers require complex mechanical assembly due to the placement of light sources and light guiding members within the cover member, complicating the assembly process.
Innovation Solution
A card insertion part design featuring a cut-out portion with protruding parts and a light-emitting part that includes a diffusion member or light guiding member, where the light sources are positioned on a frame-shaped optical member recessed within the cover member, allowing for easier assembly while enhancing decorativeness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light sources and light guiding member are disposed inside the cover member, then the card insertion part can be uniformly and prettily lighted, but the mechanical attaching work and assembling work become complicated
Solution Approach 1:
The patent extracts the light sources from the interior of the cover member and relocates them to the exterior, specifically positioning them at the rear side of the card insertion slot. This extraction eliminates the need for complex internal mounting structures while preserving the lighting function, as light can still pass through the translucent cover member to illuminate the card insertion area.
Solution Approach 2:
The patent introduces a light guiding member as an intermediary component that transfers light from the externally positioned light sources to the card insertion slot area. This mediator enables effective illumination without requiring direct placement of light sources inside the cover member, thus simplifying assembly while maintaining lighting quality.
2Illumination intensity
If light sources are disposed inside the cover member with guide parts, then the card insertion part can be lighted, but the mechanical attaching work becomes complicated
Solution Approach 1:
The patent extracts light sources from the complex internal environment where they would need to coexist with guide parts, and repositions them externally at the rear side of the card insertion slot. This separation simplifies the manufacturing process by eliminating the need to coordinate light source placement with guide part assembly, reducing manufacturing complexity while maintaining lighting functionality.
3Shape
If the card insertion part is lighted to enhance decorativeness, then the appearance is improved, but the assembly process becomes more complicated
Solution Approach 1:
The patent extracts the lighting components from the internal structure and repositions them externally, allowing the decorative lighting function to be achieved without complicating the assembly process. The external positioning of light sources at the rear side of the card insertion slot enables straightforward assembly while maintaining aesthetic appeal through uniform illumination of the translucent cover member.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables easy assembly of the card insertion part while maintaining or enhancing its decorativeness, with the light-emitting part illuminating the front and inner surfaces to facilitate card insertion and extraction, and reduces the impact of static electricity on the light sources.
Implementation Method 1
the optical member is a diffusion member or a light guiding member
Implementation Method 2
the optical member is formed with a light source arrangement recessed part in which a plurality of the light sources is disposed

AI summary
A card insertion part for a card reader includes a flange part, two separated protruding parts and a light-emitting part disposed on the front side with respect to the flange part. The light-emitting part includes light sources and an optical member such as a diffusion member. The optical member is formed with a recessed part in which the light sources are disposed and is formed so as to surround the two protruding parts and a cut-out part between the two protruding parts together. A front surface and an inner peripheral surface of the optical member are shone by lights emitted from the light sources. The front surface of the optical member is disposed on the front side with respect to a rear surface of the cut-out part, and the inner peripheral surface of the optical member is exposed between the two protruding parts.
