Connecting Rib with Concave Portion for Light Path Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display lamps in electrical products often have a discontinuous light path due to light being blocked by connecting components, leading to an incomplete light emission and potentially misleading users into thinking the product is defective.
Innovation Solution
A light-emitting device design featuring a casing with a light-transmitting port, a light source, and a casing cover with a connecting rib that includes a concave portion to prevent light blocking, ensuring a complete light path by allowing light to pass through obliquely and being irradiated to the light-transmitting gap above the connecting rib.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a connecting component is disposed between the touch control block and the combined end cover to support and fix the touch control block, then the structural stability and ease of assembly are improved, but the light path continuity deteriorates because the connecting component blocks light emitted from the lower portion
Solution Approach 1:
The harmful part (light-blocking portion of the connecting component) is extracted or removed from the light path. The patent implements this by making the connecting rib transparent or translucent, effectively removing its light-blocking property while retaining its structural support function.
Solution Approach 2:
The optical parameter (transparency) of the connecting component is changed. The patent specifies that the connecting rib be made of transparent or translucent material, changing its light-transmission parameter from opaque to transparent, thus resolving the contradiction between structural support and light path continuity.
2Ease of manufacture
If a gap is provided between the ring-shaped light-transmitting plate and the touch control block to save material and reduce cost, then the manufacturing cost is reduced, but the light path completeness deteriorates due to potential light blockage by connecting components
Solution Approach 1:
The optical parameter of the connecting rib is changed to transparent or translucent, allowing light to pass through the gap region without being blocked, thus maintaining light path completeness while preserving the cost-saving gap structure.
Solution Approach 2:
The connecting rib acts as an intermediary element that spans the light-transmitting gap. By making it transparent, it mediates between the need for structural connection (spanning the gap) and the need for light transmission (completing the light path).
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 ensures a continuous and complete light path, enhancing the appearance and usability of the product by preventing light blockage and potential user misconceptions about product defects.
Implementation Method 1
a light source disposed inside the casing; wherein the light source emits light and irradiates the light-transmitting plate above the light source to display light
Implementation Method 2
the connecting rib includes a concave portion toward an inside of the casing and configured to prevent at least a portion of light emitted by the light source from being blocked by the connecting rib

AI summary
A light-emitting device including a casing with a light-transmitting port; a light source disposed inside the casing; and a casing cover disposed in the light-transmitting port. The casing cover having an outer peripheral cover portion with an opening; an inner peripheral cover portion located in the opening; a light-transmitting gap formed between the inner peripheral cover portion with the outer peripheral cover portion; and a connecting rib spanning the light-transmitting gap to connect the outer peripheral cover portion with the inner peripheral cover portion. The connecting rib includes a concave portion extending toward an inside of the casing and configured to allow light from the light source to pass through.
