Foldable Cash Register Display Pedestal With Height Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cash register display pedestals cannot adjust height and occupy significant space due to fixed, non-foldable designs, making them inconvenient for use and storage.
Innovation Solution
A foldable pedestal structure with a base, supporting arm, retaining shaft lever, extension springs, and display loading plate that allows adjustable height and tilt angle, enabling the pedestal to be folded for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the pedestal uses a fixed, non-foldable supporting arm, then the structural stability is improved, but the storage space occupied increases
Solution Approach 1:
The supporting arm is designed to be foldable rather than fixed, allowing it to change its configuration between use and storage states. The arm can be folded horizontally against the base, transforming from an extended stable structure to a compact folded state, thus reducing storage space while maintaining structural integrity during use through pivot connections and positioning mechanisms
Solution Approach 2:
The supporting arm is divided into multiple sections connected by pivot units, allowing each segment to move independently. This segmentation enables the arm to fold into a compact configuration for storage while maintaining the necessary structural stability when extended for use, resolving the contradiction between stability and storage space
2Ease of manufacture
If the pedestal uses a fixed height design, then the manufacturing complexity is reduced, but the adaptability to different height requirements deteriorates
Solution Approach 1:
The pedestal incorporates an adjustable height mechanism where the supporting arm can be positioned at multiple height levels. The arm features positioning holes along its length that engage with corresponding pins or detents, allowing the arm to be adjusted to different heights while maintaining stable positioning at each level, thus providing adaptability without excessive manufacturing complexity
Solution Approach 2:
The supporting arm serves multiple functions: it provides structural support, enables height adjustment through positioning holes, and allows tilting of the display panel. This multi-functionality is achieved within a relatively simple structure, balancing manufacturing ease with adaptability to different height and angle requirements
3Adaptability or versatility
If the pedestal allows height and tilt adjustment, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The pedestal uses dynamic adjustment mechanisms where the supporting arm can be tilted and positioned at different heights. The tilt adjustment is achieved through pivot connections that allow the arm to rotate relative to the base, while height adjustment is accomplished through selectable positioning holes. These dynamic features provide versatility without requiring complex motorized or hydraulic systems
Solution Approach 2:
The adjustment mechanisms are designed to be manually operated without requiring external power or complex control systems. The positioning holes and pins provide self-locking capability, and the pivot connections allow easy tilting adjustment. This self-service approach enables adjustability while keeping the device complexity low

AI summary
A pedestal structure of a cash register display is disclosed, including a base, a supporting arm, a retaining shaft lever, at least one extension spring and a display loading plate. Multiple retaining grooves and an inclined slide walls are arranged on each of two side plates of the base. The supporting arm is pivoted between the two side plates through a first pivot unit, and a first end section of the supporting arm is provided with a slide opening. The retaining shaft lever passes through the slide opening and is positioned in one of the retaining grooves or on the inclined slide wall of each of the side plates. The extension spring is installed between the first pivot unit and the retaining shaft lever. The display loading plate is pivoted on a second end section of the supporting arm.
