Sliding Multiplate Holder for Wheelchair-Accessible Terminal Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic terminals, such as payment terminals, are often positioned at elevated levels, making them cumbersome for wheelchair users to access, and existing solutions for lowering them are difficult to handle and prone to interference during transactions.
Innovation Solution
A height adjustable holder with a base plate and a sliding multiplate, featuring a manipulation handle and hook mechanism, allows the electronic terminal to be securely positioned at a desired level, enabling easy access for users with disabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic terminal is positioned at an elevated level on a stationary holder, then the terminal is easily accessible for standing users, but it becomes extremely cumbersome for wheelchair users to access
Solution Approach 1:
The holder transforms from a stationary structure to a dynamic one by enabling the multiplate to slide vertically along the base plate. The manipulation handle with hook mechanism allows users to easily adjust the terminal height by sliding the multiplate to different positions and locking it in place, making the system adaptable to both standing and wheelchair users.
2Adaptability or versatility
If the electronic terminal is detached and passed to wheelchair users, then accessibility is improved, but the system becomes difficult to handle and requires special attention to cables or wires
Solution Approach 1:
Instead of detaching the terminal, the system provides continuous accessibility by allowing the multiplate to slide to a lower position that remains accessible to wheelchair users. The manipulation handle with hook mechanism enables easy positioning without detachment, eliminating cable management issues while maintaining terminal connectivity.
Solution Approach 2:
The manipulation handle acts as an intermediary mechanism between the user and the multiplate. By using the handle with its hook portion that engages with apertures or ridges on the base plate, users can easily control the multiplate position without directly handling the terminal or managing cables.
3Adaptability or versatility
If a manipulation mechanism is added to adjust height, then accessibility for wheelchair users is improved, but the device complexity increases
Solution Approach 1:
The manipulation mechanism enables the multiplate to transition between fixed and movable states. The hook portion of the manipulation handle engages with apertures or ridges on the base plate to lock the multiplate at desired positions, while allowing smooth sliding adjustment when not engaged, providing simplicity through controlled mobility.

AI summary
A height adjustable holder for a multiplate suitable to carry various types of electronic terminals is provided including: d. a base plate having a plurality of apertures in an array through the base plate or a plurality of upstanding ridges; e. a multiplate, slidingly arranged covering the overside of the base plate, where sliding surfaces are arranged between the base plate and the multiplate; f. a manipulation handle arranged between the base plate and the multiplate, which manipulation handle in a first end extends beyond the multiplate, and in an opposite end is provided with a hook portion, where the distal end of the hook, faces the base plate, and where a pivot is between the multiplate and the manipulation handle whereby the hook may be brought into engagement with an aperture or a ridge, thereby arresting the multiplate's sliding ability in one direction relative to the base plate.
