Elevator Control Panel Gap-Free Cover Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing elevator control panel design with a vertically tri-divided face cover results in gaps at the divided parts, leading to aesthetic deterioration and the introduction of foreign substances, requiring time-consuming trial-and-error adjustments to prevent gaps during attachment.
Innovation Solution
The design features a fitting member with a fitting face and a guide member with a guide face, allowing the upper and lower covers to be mounted such that they contact each other seamlessly, simplifying the attachment process and maintaining a unified appearance by adjusting the size relationship between the fitting face and guide face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the face cover is divided into upper and lower sections and independently attached to attaching members, then the attachment process becomes more flexible and easier to manufacture, but gaps are formed at the divided parts causing aesthetic deterioration and foreign substance introduction
Solution Approach 1:
The patent introduces a lower cover as an intermediary component between the upper cover and the control panel body. The lower cover includes a lower cover attaching member that mediates the attachment process, ensuring precise positioning and eliminating gaps at the divided parts while maintaining manufacturing flexibility
Solution Approach 2:
The lower cover is designed to be attached to the control panel body first, establishing a precise reference position before the upper cover is attached. This preliminary action ensures that the divided parts align perfectly without gaps, eliminating the need for trial-and-error adjustments
2Manufacturing precision
If trial-and-error adjustment is performed to prevent gaps at the divided parts, then the appearance quality is improved, but the attachment time increases significantly
Solution Approach 1:
The lower cover attaching member is pre-configured with positioning features that automatically ensure correct alignment when the lower cover is attached first. This preliminary setup eliminates the need for subsequent trial-and-error adjustments, saving significant attachment time while maintaining high appearance quality
Solution Approach 2:
The attachment process is segmented into two distinct stages: first attaching the lower cover to establish the baseline position, then attaching the upper cover to complete the assembly. This segmentation of the attachment process eliminates the need for iterative adjustments and reduces overall attachment time

AI summary
In an elevator control panel having a face cover, which is divided into upper and lower sections, the operation to mount the face cover is made to be simple, and the divided part of the face cover is made with good looks. To achieve the above object, the control panel comprises: an upper cover which is provided at the upper side of the surface of the control panel and can slide vertically; an fitting member which is disposed below the lower end of the upper cover and provided inside the upper cover, the fitting member having an fitting face extending inwardly in a horizontal direction; a lower cover which is provided at the lower side of the surface of the control panel; and a guide member which is provided inside the lower cover and below the upper end thereof, the guide member having a guide face which fits with the fitting face in such a way that the lower end of the upper cover and the upper end of the lower cover are brought into contact with each other.
