Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional lighting modules use fixing structures (screws, buckles, pressing sheets) to secure the light-transmitting plate, then the light-transmitting plate is firmly fixed, but these fixing structures shield light and reduce light emission efficiency
Solution Approach 1:
The patent removes traditional fixing structures (screws, buckles, pressing sheets) from the lighting module design. Instead, the light-transmitting plate is secured through lateral sealing between the base sidewall and light-transmitting plate sidewall, eliminating light-shielding components and improving light emission efficiency
Solution Approach 2:
The patent transitions from vertical pressing fixation to lateral sealing fixation. The sealing component is positioned between the base sidewall and light-transmitting plate sidewall, creating a seal and fixation mechanism in the lateral dimension rather than pressing from above, thus avoiding light shielding
2Strength
If conventional lighting modules use pressing sheets or pressing frames to fix the light-transmitting plate, then the light-transmitting plate is secured, but the pressure distribution is uneven causing deformation and affecting light uniformity
Solution Approach 1:
The patent eliminates pressing sheets and pressing frames that cause uneven pressure distribution. The lateral sealing mechanism provides uniform lateral support without concentrating pressure on specific points, preventing deformation and maintaining light uniformity
Solution Approach 2:
The sealing component provides localized sealing and fixation at the lateral interface between the base and light-transmitting plate, distributing the fixing force uniformly along the sidewall contact surface rather than concentrating pressure, thus maintaining structural integrity and optical uniformity
3Illumination intensity
If conventional lighting modules expose the light-transmitting plate surface, then light can transmit freely, but the surface is susceptible to scratches and external damage reducing durability
Solution Approach 1:
The patent introduces a light-transmitting protective layer (toughened glass or transparent coating) on the light-transmitting plate surface. This protective layer shields the surface from scratches and external damage while maintaining light transmission, thus improving durability without compromising optical performance
Solution Approach 2:
The patent uses composite material structures, including toughened glass or transparent coating layers combined with the light-transmitting plate. This composite structure provides both protection against external damage and maintains optical transparency, achieving both durability and light transmission
4Strength
If conventional lighting modules use additional fixing structures to secure the light-transmitting plate, then the plate is firmly fixed, but the device complexity increases
Solution Approach 1:
The patent merges the sealing function and fixation function into a single lateral sealing mechanism. The sealing component positioned between the base sidewall and light-transmitting plate sidewall simultaneously provides sealing and fixation, eliminating the need for separate fixing structures and reducing overall device complexity
Solution Approach 2:
The lateral sealing mechanism serves multiple functions: it seals the accommodating space to prevent water and dust ingress, and simultaneously fixes the light-transmitting plate in position. This multi-functional design reduces the number of components and simplifies the overall structure
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
Enhances light emission efficiency, maintains a larger light emitting angle, and improves durability by preventing external damage and pressure-induced deformation, resulting in improved illumination and extended service life.
Implementation Method 1
The sealing component is at least partially located between the light-transmitting plate sidewall and the base sidewall, and is in close contact with the light-transmitting plate sidewall and the base sidewall, respectively, so as to seal the accommodating space
Implementation Method 2
By applying a current to the semiconductor chip, excess energy can be released through recombination of carriers in the semiconductor to cause photon emission, so that the semiconductor chip can emit light
Implementation Method 3
the lens component is used for distributing light emitted by the light emitting element
