Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible light strips are used, then ease of installation and storage are improved, but mechanical rigidity deteriorates requiring additional support structures
Solution Approach 1:
The support structure is nested within the adhesive layer system. The adhesive layers are applied to different domain sides, and when domains are folded atop one another, the support structure is enclosed within this nested configuration, providing mechanical rigidity while maintaining the flexible, foldable nature of the light strip.
Solution Approach 2:
The patent uses a flexible support structure composed of multiple thin domains separated by fold lines. These thin film-like domains can be folded and bent easily for installation, yet when configured together with adhesive layers, they provide sufficient mechanical support without requiring additional rigid profiles.
2Strength
If additional extruded profiles are added for mechanical support, then mechanical rigidity is improved, but device complexity and transportation convenience deteriorate
Solution Approach 1:
The support structure is merged with the adhesive layer system and domain configuration. Instead of adding separate extruded profiles, the patent combines the support function with the existing domains and adhesive layers, eliminating the need for additional components and reducing overall device complexity.
Solution Approach 2:
The domains and adhesive layers serve multiple functions simultaneously: they provide mechanical support, enable folding and flexibility, facilitate installation through adhesion, and allow for configurational changes. This multi-functionality eliminates the need for separate dedicated support profiles.
3Ease of manufacture
If predefined sized profiles are used, then manufacturing is simplified, but transportation convenience and customization flexibility deteriorate
Solution Approach 1:
The support structure is designed to be dynamic and reconfigurable through fold lines that allow domains to be folded to different angles. This enables the same manufactured structure to adapt to various installation configurations and customization requirements without requiring different predefined sizes.
Solution Approach 2:
The support structure is segmented into multiple domains separated by fold lines. This segmentation allows the structure to be manufactured in standard units while providing flexibility through folding, enabling customization without requiring custom manufacturing for each application.
4Ease of manufacture
If fixed appearance and light emission patterns are used, then manufacturing is simplified, but design freedom and glare control deteriorate
Solution Approach 1:
The light emission pattern is made dynamic through the foldable domain structure. By folding domains to different angles, the light emission direction and pattern can be adjusted on-site, providing design freedom and glare control while maintaining simple manufacturing of the underlying structure.
