Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of light modules is used, then individual positioning flexibility is improved, but adjustment time and labor intensity increase
Solution Approach 1:
The patent combines multiple light module adjustments into a single synchronized operation. The coupling mechanism links the first and second light modules so that one adjustment operation simultaneously positions both modules, eliminating the need for separate manual adjustments of each module and thereby reducing adjustment time while maintaining positioning flexibility.
Solution Approach 2:
The adjustment mechanism is designed to perform multiple functions: it can adjust both the first and second light modules simultaneously, and can operate in different modes (synchronized adjustment, independent adjustment, or locked position). This multi-functionality allows the system to maintain flexibility while reducing the time required for adjustments.
2Measurement precision
If separate adjustment mechanisms for each light module are used, then individual positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the adjustment mechanisms for the first and second light modules into a single coupled system. Instead of providing separate adjustment mechanisms for each module, the invention uses one adjustment mechanism that simultaneously controls both modules through the coupling member, thereby reducing device complexity while maintaining positioning precision through the synchronized adjustment capability.
3Ease of operation
If light modules are positioned independently, then positioning flexibility is improved, but spatial arrangement efficiency decreases
Solution Approach 1:
The coupling member physically connects the first and second light modules, merging their positioning operations. This connection allows the modules to be adjusted simultaneously in a coordinated manner, improving spatial arrangement efficiency by reducing the space required for adjustment operations while maintaining the flexibility to position each module independently when needed.
4Productivity
If simultaneous adjustment of multiple light modules is implemented, then adjustment efficiency is improved, but mechanism complexity increases
Solution Approach 1:
The patent implements simultaneous adjustment by merging the control of multiple light modules into a single adjustment mechanism with a coupling member. This approach improves adjustment efficiency by allowing synchronized positioning of both modules in one operation, while keeping the mechanism relatively simple through the use of a straightforward coupling connection rather than a complex multi-mechanism system.

AI summary
A displacement system for simultaneous displacement of a first and a second light module of a lighting apparatus, wherein the first light module is mounted so that it can swivel about a first swivel axis and the second light module is mounted so that it can swivel about a second swivel axis, and wherein the two swivel axes extend parallel to each other. The displacement system includes a first and a second control shaft, wherein the control shafts are mounted so that they can be rotated about their respective longitudinal axis and moved linearly in the direction of their longitudinal axis, wherein the first and the second control shaft are connected in a torque-proof manner to a first and a second rotary element, so that when the first rotary element rotates, the first control shaft is rotated in the direction of rotation of the first rotary element, and when the second rotary element rotates, the second control shaft is rotated in the direction of rotation of the second rotary element, and wherein a third rotary element is provided, which cooperates with the first rotary element such that when the third rotary element rotates, the first rotary element is rotated, and wherein the first rotary element and the second rotary element cooperate such that when the first rotary element rotates, the second rotary element is rotated in the opposite direction to the direction of rotation of the first rotary element, and wherein the first and the second control shafts are mounted in such manner that as a consequence of the rotations by the first and second rotary elements caused by the rotation of the third rotary element they move linearly in opposite directions along their respective longitudinal axes, and wherein the swivel axes extend that the two light modules are swiveled simultaneously and in the same direction about their respective swivel axis.
