Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The organic EL module in existing systems rotates endlessly beyond 360 degrees, leading to potential damage from collisions with objects or users, terminal wear due to direct contact, and difficulty in setting and reproducing desired lighting spaces.
Innovation Solution
A surface light-emission system with a movable range restriction unit that limits rotation to less than 360 degrees, incorporating a motor and clutch for torque control, and a supporting part with a temporary fastening element for easy module attachment and detachment, ensuring safe operation and precise posture adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the organic EL panel is allowed to rotate endlessly in the circumferential direction to enable flexible posture adjustment, then the adaptability of lighting space is improved, but the reliability deteriorates due to potential damage from collisions with objects or users
Solution Approach 1:
The patent applies dynamics by making the support structure rotatable to allow posture adjustment of the organic EL panel. The support can rotate in the circumferential direction to change lighting orientation (direct or indirect lighting), providing flexibility while maintaining safety through controlled rotation mechanisms
Solution Approach 2:
The patent implements preliminary anti-action by providing a movable range restriction unit that prevents the support from rotating beyond a predetermined angle. This restriction unit stops the rotation before the panel can collide with surrounding objects or users, proactively preventing damage rather than reacting to it
2Device complexity
If the terminal of the shaft portion and the terminal of the bearing part are in direct contact to support and supply power, then the device complexity is reduced, but the reliability deteriorates due to terminal wear from sliding rotation
Solution Approach 1:
The patent introduces an intermediary flexible cable between the shaft portion terminal and bearing part terminal. This flexible cable transmits both mechanical support and electrical power while accommodating the rotational movement without causing wear to rigid terminals, solving the contradiction between simplicity and durability
3Ease of operation
If the organic EL panel rotates endlessly to provide continuous adjustment, then the ease of operation is improved, but the manufacturing precision deteriorates as it becomes difficult to match the panel with the predetermined lighting space posture
Solution Approach 1:
The patent applies preliminary action by setting a predetermined movable range for the support rotation before operation. The movable range restriction unit is pre-configured to limit rotation to angles that match the predetermined lighting space requirements, ensuring both ease of adjustment and precise positioning within the allowed range
