Solution Overview
Problem
Existing refrigerated displays face issues with door panel operation failure due to actuation and detection system malfunctions, leading to safety hazards, synchronization problems, and high maintenance costs, as well as difficulties in dismounting and synchronizing door panels.
Innovation Solution
The display incorporates magnetic fast-coupling/uncoupling means allowing door panels to be automatically or manually operated, with a single electric motor actuating all panels synchronously, and a mechanism to prevent user injury by releasing door panels from the movement component when intercepting an arm during closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If door panels are automatically actuated by electric motors, then operational convenience is improved, but reliability deteriorates due to motor blocking or breakdown
Solution Approach 1:
The door panel system is segmented into two independent operating modes: automatic actuation mode (with electric motors) and manual operation mode. The fast-coupling/uncoupling means enable the door panels to be quickly switched between these modes, allowing users to manually operate doors if automatic actuation fails, thus maintaining reliability while preserving automatic operation convenience.
Solution Approach 2:
The system dynamically adapts its operation mode based on conditions. The fast-coupling/uncoupling means allow the door panels to transition between coupled (automatic) and uncoupled (manual) states, enabling the system to maintain reliability by switching to manual mode when automatic actuation fails, while normally operating in automatic mode for convenience.
2Reliability
If door panels are firmly connected to actuation means, then automatic operation reliability is improved, but ease of repair deteriorates due to difficulty in dismounting
Solution Approach 1:
The connection between door panels and actuation means is made dynamic rather than static. The fast-coupling/uncoupling means enable the connection to be quickly established or released, allowing door panels to be firmly connected during automatic operation for reliability, but easily disconnected for repair or maintenance by simply actuating the fast-coupling/uncoupling mechanism.
Solution Approach 2:
The coupling mechanism is segmented into fast-coupling and fast-uncoupling functions, allowing the door panel assembly to be quickly separated from the actuation means for repair while maintaining firm connection during normal operation. This segmentation enables independent maintenance of door panels without affecting the actuation system.
3Adaptability or versatility
If multiple electric motors are used to actuate door panels, then operational independence is improved, but device complexity increases
Solution Approach 1:
Multiple door panels are actuated by a single electric motor through a common actuation means that controls all door panels simultaneously. This merging approach reduces the number of motors from multiple independent units to one shared motor, thereby reducing device complexity while maintaining the ability to actuate all door panels independently through the fast-coupling/uncoupling mechanism.
4Object-affected harmful factors
If detection means are used to detect user presence, then operational safety is improved, but device complexity increases
Solution Approach 1:
The fast-coupling/uncoupling means are pre-configured to enable rapid manual operation of door panels. Detection means can detect user presence and trigger uncoupling of door panels from automatic actuation before closing, preventing injury. The preliminary preparation of the fast-coupling/uncoupling mechanism ensures that safety intervention can be executed immediately when detected, adding safety without requiring complex real-time control systems.

AI summary
A display (200) comprises at least one revolving door panel (3) hinged to a box frame (1) by means of hinging means actuated by actuation means (M); said display (200) comprising a movement component (61) that can be coupled with the door panel (3) to move the door panel (3), as well as fast coupling/uncoupling means (92, 93) for the fast coupling of the movement component (61) with the door panel (3) to actuate the door panel (3) by means of the actuation means (M), and permit the fast uncoupling of the movement component (61) from the door panel (3) to move the door panel (3) manually, independently from the actuation means (M).
