Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LEDs are used to replace discharge tubes, then energy efficiency and lifespan are improved, but glare control deteriorates because LEDs produce concentrated bright points of light
Solution Approach 1:
The linear light source is divided into multiple individual LED modules arranged along the tube, with each LED being a separate replaceable unit. This segmentation allows glare control to be addressed at the individual LED level through lenses and mirrors, while maintaining the overall linear lighting function.
Solution Approach 2:
Each LED is equipped with its own optical system including a lens for light distribution and mirrored edges for glare reduction. This local optimization of light control at each LED position eliminates the concentrated glare points while preserving the energy efficiency benefits of LEDs.
2Reliability
If complete lamp replacement is performed when LEDs fail, then reliability is maintained, but cost increases significantly
Solution Approach 1:
The lighting system is segmented into replaceable LED modules that can be individually replaced within the existing lamp housing. This allows replacement of only the failed LED module rather than the entire lamp assembly, reducing material consumption and cost.
Solution Approach 2:
The design enables recovery and reuse of the lamp housing, optical components, and electrical connections. Only the failed LED module is discarded and replaced, maximizing the utilization of existing components and minimizing waste.
3Object-affected harmful factors
If glare-reducing elements are added to LED fixtures, then glare control is improved, but device complexity increases
Solution Approach 1:
The glare control elements (lenses and mirrored edges) are merged with each individual LED module, creating an integrated optical unit. This combination eliminates the need for separate glare control mechanisms and simplifies the overall fixture design.
Solution Approach 2:
Each LED module is designed as a universal unit that combines light emission, light distribution, and glare control functions. This multi-functionality reduces the number of separate components needed in the overall lighting system.
4Stability of the object's composition
If rigid connections are used between circuit board and glare suppressor, then structural stability is improved, but thermal deformation occurs due to different expansion rates
Solution Approach 1:
The connection between the circuit board and glare suppressor is made flexible rather than rigid, allowing the components to move independently in response to thermal expansion. This dynamic connection maintains structural stability while accommodating differential thermal expansion.
5Ease of repair
If LED modules are made replaceable, then ease of maintenance is improved, but connection reliability may deteriorate
Solution Approach 1:
The LED modules are segmented as independent replaceable units with standardized connectors. This segmentation enables easy removal and replacement while the standardized connection design ensures reliable electrical and mechanical contact.
Solution Approach 2:
A standardized socket or connector acts as an intermediary between the replaceable LED module and the lamp housing. This intermediary component ensures reliable connection while facilitating easy module replacement without direct manipulation of electrical contacts.

Function Achieved in This Case
Enables glare-free, uniform lighting with easy installation and maintenance, ensuring efficient heat dissipation and preventing thermal deformation, while allowing for flexible light source lengths and tool-free bulb replacement.
Implementation Method 1
A very strong, but concentrated light source is first widened by the optical lens. For this purpose, a plano-convex lens element is used, with its flat side facing the LED.
Implementation Method 2
Each lens has a recess surrounded by sloping, mirrored edges. The areas around the recess may be truncated pyramid-shaped.
