Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional lamp structure is used, then the lamp can provide lighting function, but it cannot be easily moved or positioned to necessary locations
Solution Approach 1:
The lamp is divided into separate functional modules: a removable lighting head containing the OLED lighting sheet, and a base unit containing the battery and control circuitry. This segmentation allows the lighting head to be easily moved and positioned independently while maintaining electrical connection through a flexible cable, thus improving positioning flexibility without significantly increasing overall device complexity.
Solution Approach 2:
The lamp incorporates a flexible cable connecting the lighting head to the base, allowing dynamic positioning and movement of the lighting head to various locations. The flexible cable enables the lamp to adapt to different spatial configurations and user needs, transforming a static structure into a dynamic, reconfigurable system that improves adaptability while maintaining simple device architecture.
2Illumination intensity
If OLED lighting sheet is used, then brightness and thin film structure are achieved, but manufacturing complexity increases
Solution Approach 1:
The patent combines the OLED lighting sheet with a transparent film and protective housing into an integrated lighting unit assembly. This merging approach allows the delicate OLED component to be pre-assembled and tested as a complete module before final installation, simplifying the manufacturing process by reducing the number of separate assembly steps and handling requirements for the sensitive OLED material.
Solution Approach 2:
The use of a transparent film as both a protective cover and a structural component simplifies manufacturing by eliminating the need for separate protective housings. The thin film structure protects the OLED lighting sheet while maintaining its flexibility and thin profile, reducing assembly complexity compared to traditional rigid housing approaches.
3Length of moving object
If multiple components are stacked to create thin lighting unit, then thickness is minimized, but assembly precision requirements increase
Solution Approach 1:
The lighting unit employs a nested structure where the OLED lighting sheet is positioned within a recess of the transparent film, which in turn is housed within the protective casing. This nesting arrangement naturally aligns the thin components vertically, minimizing the need for high-precision lateral positioning while achieving minimal overall thickness through layered stacking.
Solution Approach 2:
The patent incorporates rounded edges and curved transition zones in the housing structure that accommodate minor dimensional variations in the stacked thin components. These curved features provide tolerance compensation, allowing the assembly to achieve minimal thickness without requiring extremely tight manufacturing tolerances on each individual component.
