Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvefixing strengthVSAvoidlight emission efficiency
Core Design Contradiction:
StrengthVSIllumination intensity

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvefixing strengthVSAvoidlight uniformity
Core Design Contradiction:
StrengthVSManufacturing precision

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Inventive Principle:
Principle #3Local quality

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

Engineering Contradiction:
Improvelight transmissionVSAvoiddurability
Core Design Contradiction:
Illumination intensityVSReliability

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

Inventive Principle:
Principle #30Flexible shells and thin films

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

Inventive Principle:
Principle #40Composite materials

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

Engineering Contradiction:
Improvefixing strengthVSAvoidstructure complexity
Core Design Contradiction:
StrengthVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)
