Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paddle-style handset controls for height adjustable desks require laborious installation and positioning of discrete up and down switches, complicating assembly and potentially leading to misalignment and inconsistent tactile feedback.
Innovation Solution
A paddle-style handset control with an integrated two-way switch featuring a rocker and cantilevers that triggers up and down contactors through tilting, simplifying assembly by eliminating complex connections and ensuring consistent tactile and audio feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two discrete switches are used for controlling up and down movement, then the control function is achieved, but the assembly process becomes laborious and complex positioning is required
Solution Approach 1:
The patent combines two discrete switches into a single integrated two-way switch assembly. The switch body incorporates both up and down contactors within one unit, and the rocker serves as a common actuating element for both directions. This merging eliminates the need to separately install and position two independent switches, significantly simplifying the assembly process while maintaining full control functionality.
Solution Approach 2:
The rocker serves multiple functions: it acts as the actuating element for both up and down contactors, provides tactile feedback for user interaction, and ensures consistent positioning relative to the contactors. This multi-functional design eliminates the need for separate positioning mechanisms that would be required if two discrete switches were used, thereby simplifying assembly.
2Ease of operation
If two discrete switches are used, then control functionality is provided, but positioning alignment becomes complex and time-consuming
Solution Approach 1:
By integrating both contactors into a single switch body with a common rocker, the patent eliminates the need for precise positioning between two separate switches. The rocker is designed to simultaneously engage both contactors at predetermined positions, ensuring consistent alignment without requiring complex positioning procedures during assembly.
Solution Approach 2:
The switch body and rocker are designed as pre-integrated components with built-in alignment features. The rocker's geometry and the contactor positions are predetermined during manufacturing, ensuring that when the assembly is installed, the alignment is automatically correct without requiring additional positioning adjustments on the installation site.
3Ease of operation
If discrete switches are used, then control is achieved, but the risk of misalignment increases leading to inconsistent tactile feedback
Solution Approach 1:
The integration of both contactors into a single switch body with a common rocker ensures that the relative positions of the contactors and the rocker are fixed and precise. This eliminates the misalignment issues that would occur with two discrete switches, ensuring consistent tactile feedback every time the user actuates the control.
Solution Approach 2:
Instead of having two independent switches that could potentially misalign, the patent inverts the approach by having one unified switch body that inherently maintains correct alignment. The rocker is designed to engage both contactors simultaneously, and any deviation from the predetermined position is mechanically prevented by the integrated structure, ensuring reliable tactile feedback.

AI summary
A paddle-style handset control and a height adjustable desk; the paddle-style handset control includes a bracket and paddle piece mounted on the bracket, the paddle piece including a horizontal connecting section in the bracket and a manipulating section extending out of the bracket; the paddle-style handset control further includes a two-way switch including a switch body installed on the paddle piece and a rocker, the switch body includes up and down contactors; the rocker is provided thereon with a rotating shaft, one end of the rocker being connected to the switch body via the rotating shaft, another end restrained on the bracket; the paddle piece tilts driving the rocker to rock relative to the switch body thereby triggering the up or down contactors. In the paddle-style handset control, the two-way switch as an integrated structure is mounted on the paddle piece, which facilitates assembly of the paddle-style handset control.
