Solution Overview
Problem
The process of switching a workbench between a support state and a folded state is complex, requiring separate rotations of supporting structures on both sides, leading to a poor user experience.
Innovation Solution
A workbench design featuring a bearing platform, two supporting structures, a control member, and a connecting assembly that allows the supporting structures to be unfolded or folded via a single control member, facilitated by a connecting assembly that includes movable members and sliding grooves to ensure stable and synchronized rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate rotation of supporting structures on both sides is required to switch between support state and folded state, then the workbench can be switched between states, but the operation process becomes complex and user experience deteriorates
Solution Approach 1:
The patent combines the control of two supporting structures into a single control member. The control member is connected to both supporting structures through connecting assemblies, allowing one control member to simultaneously control the rotation of both supporting structures. This merging of control functions simplifies the operation process from requiring separate rotations to a single unified action.
Solution Approach 2:
The control member serves multiple functions: it controls both supporting structures simultaneously, and through the connecting assembly with sliding grooves and movable members, it achieves synchronized rotation while maintaining structural stability. The connecting assembly itself becomes a multi-functional component that provides both connection and motion control.
2Ease of operation
If a connecting assembly with movable members and sliding grooves is used to enable synchronized rotation, then ease of operation improves, but device complexity increases
Solution Approach 1:
The connecting assembly employs a nested structure where movable members are positioned within sliding grooves. The sliding grooves are formed on the supporting structures, and movable members fit within these grooves, creating a nested arrangement that guides motion while maintaining a compact overall structure. This nesting reduces spatial requirements while enabling the synchronized rotation function.
3Reliability
If supporting structures are rotated to preset positions for support state, then stable support is achieved, but the switching process becomes time-consuming
Solution Approach 1:
The connecting assembly is pre-configured with sliding grooves and movable members that guide the supporting structures to their preset positions during rotation. The geometric constraints built into the connecting assembly automatically ensure that when the control member is actuated, the supporting structures rotate to the correct preset positions without requiring additional adjustment steps, thereby reducing switching time while maintaining support stability.

AI summary
A workbench is provided. The workbench includes a bearing platform, two supporting structures, a control member and a connecting assembly. The bearing platform includes a bearing surface and a back surface away from each other. The two supporting structures are rotatably mounted on the back surface, respectively. The control member is movably connected to the bearing platform. The connecting assembly is configured for connecting the control member to the two supporting structures. The control member is capable of driving the two supporting structures to rotate via the connecting assembly under the action of an external force. When the workbench is in the folded state, both of the two supporting structures are adjacent to the back surface. When the workbench is in the support state, the two supporting structures are capable of supporting the bearing platform.
