Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If traditional glass insulating layer with tin layer is used, then electrical insulation and conductivity are achieved, but heavy metal pollution and safety hazards are caused
Solution Approach 1:
The patent removes the glass insulating layer containing heavy metal impurities and the tin layer from the lamp base structure. Instead, it uses a plastic insulating piece for insulation and a conductive rivet for electrical connection, completely extracting the harmful components while maintaining functional requirements.
Solution Approach 2:
The patent changes the material parameters of the insulating component from glass to plastic, and the conductive component from tin layer to conductive rivet. This material substitution eliminates heavy metal content while preserving electrical insulation and conductivity functions.
2Ease of manufacture
If thin metal shell is used, then manufacturing cost is reduced, but inward sinking deformation occurs during mounting
Solution Approach 1:
The patent performs preliminary reinforcement by adding a plastic insulating piece to the thin metal shell before the mounting process. This pre-reinforcement prevents inward sinking deformation when the light bulb is screwed into the lamp holder, allowing the use of thin metal shell while maintaining structural strength.
Solution Approach 2:
The patent creates a composite structure by combining the thin metal shell with a plastic insulating piece. The plastic component reinforces the metal shell, preventing deformation during mounting while maintaining the cost advantages of thin metal construction.
3Object-generated harmful factors
If non-welded design with conductive rivet is used, then environmental friendliness is improved, but assembly complexity increases
Solution Approach 1:
The patent segments the electrical connection function into two separate components: a plastic insulating piece for insulation and a conductive rivet for electrical connection. This segmentation eliminates the need for welding and soldering, making the design environmentally friendly while organizing complexity into distinct, manageable parts.
Solution Approach 2:
The conductive rivet acts as an intermediary component that bridges the plastic insulating piece and the electrode. It provides both mechanical fastening and electrical connection functions, simplifying the overall assembly process compared to traditional welded designs while maintaining environmental friendliness.
