Power-Supplying Device Assembly Using Preliminary Anti-Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of existing power-supplying devices is complicated due to the need to apply a counterforce against the initial biasing force of the coil spring when attaching the turning member to the support, especially when the sliding door is fully closed.
Innovation Solution
The device includes a support with a primary and secondary shaft, a first-locking section, and an engaged part, allowing the first support and turning member to be moved opposite to the coil spring's biasing direction to establish an engaging condition where the coil spring is elastically deformed, facilitating assembly by maintaining the initial biasing force and enabling easy assembly of the supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the coil spring is assembled in the neutral condition, then the assembly process is simple, but the initial biasing force cannot be applied to the coil spring
Solution Approach 1:
The patent applies preliminary action by pre-deforming the coil spring during the assembly process. The first support is temporarily displaced in the direction opposite to the biasing direction before final assembly, allowing the coil spring to be installed in a deformed state that establishes the initial biasing force. This preliminary deformation action enables the coil spring to exert the required initial force once assembled in the neutral condition.
Solution Approach 2:
The patent employs preliminary anti-action by applying a force in the direction opposite to the biasing direction during assembly. The first support is deliberately moved opposite to the natural biasing direction of the coil spring, creating a counteracting force that allows the spring to be installed without requiring excessive assembly force. This preliminary counter-action eliminates the need to apply force against the initial biasing force during assembly.
2Force
If the coil spring is pre-deformed to apply initial biasing force, then the biasing force is established, but assembly work becomes difficult due to resistance from the biasing force
Solution Approach 1:
The patent applies inversion by reversing the conventional assembly approach. Instead of assembling the coil spring in the neutral condition and then deforming it, the first support itself is deformed in the direction opposite to the biasing direction during assembly. This inverted approach allows the coil spring to be installed in its natural state while the support carries the deformation, eliminating resistance during assembly.
Solution Approach 2:
The patent uses the first support as an intermediary that temporarily carries the deformation. Rather than deforming the coil spring directly during assembly, the first support is displaced to create the necessary deformation condition. This intermediary approach allows the deformation to be applied to the support rather than the spring, facilitating easier assembly while still establishing the initial biasing force.
3Ease of manufacture
If the first support and turning member are assembled in neutral condition, then assembly is easy, but the engaging condition cannot be established
Solution Approach 1:
The patent applies dynamics by making the assembly process sequential and dynamic. The first support is temporarily displaced to establish the engaging condition between the engaged part and engaged portion, and only after this engagement is confirmed does the support return to the neutral condition. This dynamic, sequential approach ensures the engaging condition is properly established while maintaining assembly ease.

Function Achieved in This Case
This configuration enhances assembly workability by maintaining the initial biasing force, allowing the turning member to be supported by the support, and simplifies the assembly process while preventing the restriction portion from interfering with the neutral condition.

AI summary
There is provided a power-supplying device and an assembly method thereof. By causing a first-turning member, which locks with an one end of a coil spring by a first-locking section, and a first support, which locks with the other end thereof by a second-locking section, to rotate relative to each other in the direction that is opposite to the biasing direction, and causing an engaging part and an engaged part to be in an engaged state by engaging with each other, thereby, maintaining the state where the initial biasing force is being imparted to the first turning member, is enabled, and the first support and a second support member are easily assembled to each other to make a turning member be supported, and thus, assembly properties can be made enhanced.
