Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control mechanisms for engineering and industrial applications are insufficiently robust to withstand high cycle counts and maximum forces, making them fragile and unsuitable for mobile equipment like construction machine cabs.
Innovation Solution
A remote controller mechanism with a strong and compact structure, featuring two pivots per axis, a main frame, an auxiliary frame, and an intermediate frame with a swivel joint, allowing the control lever to pivot on both axes while being detected by sensors, ensuring robustness and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the remote control mechanism uses two pivots (one for each axis), then the structure is simple, but the mechanism becomes fragile and cannot withstand high forces and cycle counts
Solution Approach 1:
The mechanism is divided into separate main frame and auxiliary frame components, each with their own pivots. The main frame handles X-axis movement while the auxiliary frame handles Y-axis movement, distributing mechanical stresses across separate structural elements rather than concentrating them in a single integrated structure.
Solution Approach 2:
The invention adds a third dimension to the pivot arrangement by positioning pivots at opposite ends of each axis rather than concentrating them in a single plane. This spatial distribution across multiple dimensions increases structural rigidity and resistance to torsional forces while maintaining the two-degree-of-freedom functionality.
2Reliability
If two supplementary pivots are added per axis to reinforce the mechanism, then the mechanism becomes stronger, but the device complexity increases and dimensions increase
Solution Approach 1:
The main frame and auxiliary frame are merged into a single integrated assembly that shares common mounting points and coordinate systems. This merging allows the two-frame structure to achieve the strength of multiple pivots per axis while maintaining a compact, unified design that does not significantly increase overall device complexity.
3Strength
If the mechanism dimensions are increased to provide mechanical strength, then the structure becomes stronger, but the device cannot be incorporated into mobile equipment with limited space
Solution Approach 1:
The auxiliary frame is positioned and configured to nest within or alongside the main frame structure. The two frames are arranged in a space-efficient configuration where their respective pivot mechanisms interlock or align, achieving the structural strength of a multi-pivot design while minimizing the overall envelope dimensions of the remote control device.

AI summary
A remote controller includes a fixed body equipped with pivots in a first axis and pivots in a second axis, together with an operating lever. The remote controlling further includes a main frame configured to pivot about the axes to transmit pivoting movement of the lever to a pivoting sensor. The main frame is coupled by pivots to the lever. The lever has two pairs of arms to control the pivoting of the main frame and the pivoting of the auxiliary frame. The auxiliary frame is coupled to the lever by an intermediate frame. The intermediate frame is coupled to the auxiliary frame by a swivel. The frames are located under a plane of the axes and the lever is located above the plane of the axes.
