Problem

Existing battery pack charging solutions require separate mobile chargers that occupy space and involve additional wiring, lacking a compact and space-efficient installation option for wall integration.

Innovation Solution

A wall-mounted or wall-installed charging device with a housing part and electronic module that converts mains voltage to charging voltage, featuring a contact arrangement for battery packs, allowing for detachable mechanical connection without tools and utilizing existing building electrical infrastructure for power supply.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate mobile charger is used for battery packs, then the charging function is provided, but additional space is occupied and additional wiring is required

Engineering Contradiction:
Improvecharging functionVSAvoidspace occupation
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The charging device merges the charging function with wall-mounted housing, integrating what was previously a separate mobile charger into a fixed wall installation. This combines the charging capability with the building structure, eliminating the need for separate charger units and reducing space occupation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The charging device transitions from a portable, mobile form factor to a wall-mounted installation, utilizing the vertical dimension and wall surface area. This dimensional change allows the charging function to be embedded in the building structure rather than occupying floor or table space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a separate mobile charger is used for battery packs, then the charging function is provided, but additional wiring is required

Engineering Contradiction:
Improvecharging functionVSAvoidwiring requirements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The charging device merges the power supply connection with the building's existing electrical infrastructure. By integrating the charger into the wall, the device utilizes the building's permanent wiring system, eliminating the need for separate power cords and plugs that would be required for mobile chargers.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The wall-mounted charging device utilizes the building's existing electrical infrastructure to provide power. The system serves itself by tapping into the permanent wiring already present in the building, rather than requiring external power connections for each charging unit.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If battery packs are stored separately, then they are accessible, but space is wasted and organization is reduced

Engineering Contradiction:
Improvebattery accessibilityVSAvoidstorage space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The charging device merges the storage function with the charging function in a single wall-mounted unit. Battery packs are stored in the housing structure and charged in place, combining what were previously separate functions into one integrated system that saves space while maintaining accessibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The wall-mounted housing serves multiple functions simultaneously: it provides structural mounting, houses the electronic module, stores battery packs, and provides charging capability. This multi-functionality eliminates the need for separate storage and charging equipment.

Inventive Principle:
Principle #6Universality (Multi-functionality)
