Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional glass and metal materials with incandescent bulbs are used, then lighting function is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent changes the material parameters from traditional glass and metal to plastics material for both body and lens. This parameter change enables peripheral welding instead of complex assembly processes, simplifying manufacturing while maintaining the submersible spotlight's functionality and structural integrity.
Solution Approach 2:
The patent uses composite plastic material construction for both the body and lens, replacing the traditional glass-metal composite structure. This composite plastic approach allows for simplified manufacturing processes including peripheral welding, reducing both manufacturing complexity and cost while achieving the desired optical and structural properties.
2Ease of manufacture
If traditional glass and metal materials with incandescent bulbs are used, then lighting function is achieved, but manufacturing cost increases
Solution Approach 1:
The patent changes the material parameters from traditional glass and metal to plastics material for both body and lens. This parameter change enables peripheral welding instead of complex assembly processes, simplifying manufacturing while maintaining the submersible spotlight's functionality and structural integrity.
Solution Approach 2:
The patent adopts plastics material instead of expensive glass and metal materials, using more economical materials that can be easily molded and welded. This substitution of cheaper materials directly reduces manufacturing cost while achieving the required performance through alternative design approaches.
3Use of energy by moving object
If high power LEDs are used, then lighting efficiency is improved, but heat dissipation requirements increase device complexity
Solution Approach 1:
The patent uses multiple low-power LEDs instead of fewer high-power LEDs. By employing a larger number of LEDs with lower individual power consumption, the total lighting output is achieved without generating excessive heat at any single point, thereby eliminating the need for complex heat dissipation systems.
Solution Approach 2:
The patent extracts the heat dissipation function from the device design by using low-power LEDs that generate minimal heat. This extraction eliminates the need for separate heat dissipation components and systems, simplifying the overall device structure while maintaining energy efficiency.
4Use of energy by moving object
If low-power LEDs are used in greater numbers, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent combines multiple low-power LEDs into a single integrated lighting assembly mounted on the front face of the plastic body. This merging approach achieves the desired lighting effect through coordinated operation of multiple LEDs while maintaining a simple unified structure, avoiding the complexity that would arise from managing separate LED modules.

AI summary
This spotlight comprises a body (1) with a transparent front (2) and has LED's (5) as light-emitting elements. This spotlight is characterised in that the body (1) and the transparent front (2) are made of plastics material and are peripherally welded together and hence tightly fitted to each other in a sealed arrangement. The body (1) is concavely shaped and the printed circuit (4) with the LED's (5) is securedly attached to said body at this latter's open front end, said body (1) having at its centre an inner pillar (6) having a hollowed-out portion (7) and an outer open end (8) being adapted to receive the spotlight's electric connections (10, 11) that will be fitted to it. The LED's (5) are of a low-power type and are provided in great number.
